Conveyor Belt Manufacturer Ultimate Guide (2026): Types, Grades and How to Choose

A conveyor belt manufacturer is worth shortlisting only when it can show you the carcass construction, cover grade and test records behind the belt it quotes, not merely a price per meter. We are Ningbo Sinoconve Belt Co., Ltd., brand SINOCONVE, and we have been building belts in Ningbo, China since 1988. Ten production lines — eight for fabric carcass and two for steel cord — with more than 200 employees and over 1,500 industrial customers taught us one uncomfortable lesson: most belt failures are decided long before the belt is spliced. They are decided in the request for quotation.

This guide is written for the people who carry that decision — procurement engineers at mines, quarries, cement plants, ports and EPC contractors, plus the maintenance superintendents who get the phone call at 2 a.m. when a 1,200 mm belt rips at the transfer point. We work through belt types, cover grades, carcass choices, components, supplier selection, pricing, samples, inspection and total cost of ownership. Where we quote industry ranges, we label them as typical and ask you to confirm against the actual duty. Nothing here replaces an approved drawing and a real duty calculation; it should make that conversation shorter and sharper.

01What Does a Conveyor Belt Manufacturer Actually Deliver?

Buyers often think they are buying rubber. You are not. You are buying a composite whose job is to survive a specific duty for a predictable number of hours. That composite has four decisions baked into it: the carcass (fabric plies or steel cords), the cover compound and grade, the edge construction, and the splice method you will use on site.

We run a real conveyor belt factory, which means we control calendering, building, vulcanizing and cutting inside our own walls. That matters to you for practical reasons rather than patriotic ones. When cover compound is calendered in-house, we can change an abrasion-resistant formulation for a specific quarry without waiting for a third party. When the press is ours, a 200 m emergency run can jump the queue on a quiet week. When the lab is ours, we can pull a splice sample and give you a tensile figure before the belt leaves the yard.

What a manufacturer should hand you, as a minimum: a drawing-level specification with ply count, carcass type, cover thickness on both faces, total belt thickness and tolerance; the cover grade with the standard it is tested against; the belt weight per square meter; the recommended minimum pulley diameter; and the tensile strength per unit width at the splice. If a supplier cannot produce those numbers in writing, you are buying a commodity, not a belt.

We also ask questions before we quote. Belt width and troughing angle. Material, lump size, bulk density. Tonnes per hour against design capacity. Centre distance and lift. Drive power, pulley diameters, take-up type. Ambient and material temperature. Whether the belt runs outdoors, in a tunnel, or under a covered conveyor gallery. Whether there is a risk of oil, chemicals or fire. That list is not bureaucracy — it is how we avoid selling you a 4-ply belt where 5 plies with a thicker top cover would have lasted twice as long.

02Conveyor Belt Types: A Practical Field Guide

Every belt catalogue looks similar at first glance. The difference shows up when you match belt families to the mechanism that actually destroys belts in your plant. In hard-rock quarries it is impact and abrasion at the loading point. In cement it is heat and fine, alkaline dust. In ports it is salt, humidity and long centre distances. In food and packaging it is hygiene, oil and washdown. Pick the family first, then the grade.

Ranges in the table are typical and should be confirmed against the actual duty. A 1,200 mm EP belt with 5 plies and an 8 mm top cover is a very different asset from the same width carrying 3 plies and 4 mm of cover, even though both are described on a packing list as "EP conveyor belt".

If you need a broad view of the conveyor belt supplier catalogue before narrowing down, compare families side by side rather than one family in isolation. For general bulk handling with a mix of aggregate, ore and clinker, most of our customers settle on an industrial conveyor belt built on a multi-ply fabric carcass, then choose the cover grade for the material.

03Cover Grades: DIN 22102, RMA, AS 1332 and ISO 340

The cover is the part you can see, so it is the part everyone argues about. Grades describe two different properties that are easy to confuse: wear resistance and flame resistance. A belt can be excellent at one and poor at the other.

Abrasion grades in plain language

Under DIN 22102, rubber covers are graded roughly into wear classes W, X, Y and Z, where W is the most abrasion-resistant and Z the least. RMA grades run on a different scale (Grade I, Grade II) and AS 1332 uses yet another set of categories. Those systems are not numerically interchangeable. A supplier who says "Grade M equals DIN W" is simplifying, and the simplification can cost you money in either direction. What travels with a serious quotation is a compound report: tensile strength, elongation at break, abrasion loss in mm³, and adhesion values between plies and between cover and carcass. Ask for the actual test method, not just the number.

Two field notes. First, a harder cover is not automatically better — very hard compounds crack under repeated small-radius flexing, which is why a belt that wears like iron on a straight run can fail on a small pulley. Second, grade comparisons across DIN, RMA and AS 1332 should always be confirmed against the actual duty and the approved drawing, because the test conditions behind each standard differ.

How we match grade to a real application

For a granite quarry with 900 mm lumps dropping 2.5 m onto the belt, we usually propose an abrasion grade at the top of the range with a thicker cover — 8 mm rather than 6 mm — and we accept the extra belt weight. For a cement plant moving clinker at 120–150 °C, we shift money from abrasion resistance into a heat-resistant compound and add a heat barrier if the temperature spikes. For an underground coal mine, flame resistance under ISO 340 stops being a preference and becomes a pass/fail condition, and we will not start production until we see the tender clause. Getting this wrong is the most expensive mistake in belt sourcing, because the belt itself may only be 20–30% of what a premature failure costs once you add labour, crane time, spillage cleanup and lost production.

04Carcass Selection: EP vs NN, Ply Count and Belt Thickness

The carcass carries the tension, so it decides whether your take-up sits where it should after six months. Polyester warp with nylon weft (EP) has low elongation and good dimensional stability; nylon warp with nylon weft (NN) stretches more and absorbs impact better. That single difference explains most of the arguments we referee between plant engineers.

What is the right number of plies?

Ply count is not a quality ladder. More plies does not mean a better belt; it means a thicker, stiffer belt that needs larger pulleys and is harder to splice. The right ply count is the one that delivers the required tensile strength per unit width at your actual working tension with an acceptable safety factor, while still wrapping the smallest pulley in the drive without exceeding the belt's allowable fatigue. A common mistake in reordering is copying the old nameplate. If the conveyor was uprated — higher tonnage, faster belt speed, a different drive — the old ply count may now be marginal. Send us the current duty and we will recalculate rather than reprint history.

Thickness follows from two decisions you can measure on site: carcass construction and cover thickness on the carrying side and the pulley side. Buyers frequently over-specify top cover and under-specify the bottom cover, then wonder why the belt tracks badly and wears at the edges. The pulley-side cover protects the carcass from idler and pulley contact, and on a long conveyor with many return idlers that surface matters as much as the one you can see from the walkway.

We publish belt structures and a full rubber conveyor belt specification route so that you can compare ply and cover combinations before requesting a price. If your plant has both heavy and light duty conveyors, our engineers can also review the EP conveyor belt specification in detail and flag where a single standardised belt width and ply count would simplify your warehouse without compromising safety.

05Steel Cord Conveyor Belts for Long-Distance Duty

Above roughly 1,000 m of centre distance, or when a single lift exceeds what fabric can hold at a sensible ply count, steel cord becomes the rational choice. A steel cord conveyor belt puts the tension into brass-coated cords laid parallel in the belt direction, giving very low elongation and very high breaking strength in a relatively thin profile.

The trade-offs are real. Steel cord belts do not tolerate a badly aligned structure: they need well-squared pulleys, correct crown, proper training and a splice done by trained hands, typically using a press with controlled temperature and pressure. Cord corrosion is the hidden killer. Water entering through a damaged cover or a poorly sealed edge will attack cords long before the belt looks worn out, which is why we inspect edge damage seriously and recommend edge repair rather than "we will watch it".

On our two steel cord lines we produce belts for long overland conveyors, downhill regeneration duty and high-lift applications. Typical strength ranges run from the low hundreds up to several thousand N/mm, but the figure that matters is the one your conveyor calculation requires — confirm it against your approved duty and drawings. For long-distance mining projects, cable-belt or steel cord is often part of a package where the owner also needs idlers, pulleys and a delivery schedule tied to construction milestones.

06Specialty Belts for Heat, Fire, Oil, Cold and Steep Incline

Once the mainstream belts are settled, the headaches usually come from the awkward conveyors. Clinker at 150 °C. Coal dust and a flame-resistance clause. Sunflower seed and oil mist. A freezer warehouse at −25 °C. A 35° incline inside a building with no room for a longer conveyor. Each of these has a belt family that fits, and choosing wrong is expensive.

Heat resistant belts use compounds that resist hardening and cracking; they are matched to a temperature range and a lump size, because a 400 mm lump of hot sinter transfers heat differently from a bed of fine hot ash. Our heat resistant conveyor belt range and the accompanying heat resistant belt test reports are the two documents procurement usually asks for first in cement and steel projects.

Fire resistance is a compliance topic, not a marketing topic. Underground coal and enclosed tunnels typically require belts tested to ISO 340, often with additional surface resistance criteria, and we recommend refusing any offer where the certificate is described verbally rather than attached. Oil-resistant and chemical-resistant covers protect the compound from swelling; abrasion-resistant covers protect it from wear; cold-resistant covers stay flexible where a standard compound would crack. Chevron and sidewall belts solve geometry rather than chemistry — they let you run a steep incline in a short footprint, provided the cleat pattern, pitch and base belt are specified together rather than as an afterthought. On every one of these families, treat catalogue ranges as indicative and confirm against the actual duty.

07V-Belts and Transmission Belts: The Other Half of the Machine

Most belt-driven equipment on a bulk handling site is not a conveyor at all. Crusher drives, screens, fans, compressors, pumps and the small conveyors around a batching plant run on V-belts. Plants that buy conveyor belting from one source and drive belts from a local shop often end up with mismatched quality, and the drive belt failure stops the same production line as a belt rip.

As a transmission belt manufacturer as well as a belt maker for conveying, we supply wrapped classical belts, narrow section belts, raw-edge cogged belts for small pulley diameters, banded belts for pulsating loads, ribbed belts and synchronous belts. The selection logic is mechanical rather than commercial: pulley diameter and speed decide whether a cogged belt is needed; shock load decides whether a banded set is safer than three loose belts; the required synchronous position decides whether a timing belt replaces a friction belt entirely. Our V-belt manufacturer programme covers industrial and automotive profiles, and we match length tolerance and branding to the drawing when a distributor needs private label stock.

For maintenance teams, the practical wins are boring ones. Keep matched sets matched. Check sheave wear before blaming the belt. Store belts flat or on a large-radius hook, away from sunlight and ozone sources. And when you convert a drive to a new belt section, recalculate rather than guess, because a small change in sheave diameter changes belt life substantially.

08Conveyor Components: Where Uptime Is Really Won

We have never met a maintenance manager who blamed a bearing for a good day, but we have met plenty who lost a week to one. Conveyor components decide whether your belt reaches its rated life. Belts do not usually fail from tension; they fail from mistracking, seized idlers, sharp-edged loading and belt-to-structure contact.

The basics we ship alongside belts: troughing idlers, return idlers, impact idlers at the loading point, garland idlers for flexible catenary runs, training and self-aligning idlers, pulleys, and the brackets that hold them all in alignment. Our conveyor rollers range covers steel rollers with labyrinth sealing for dusty and coastal environments, where moisture ingress rather than dust is what kills bearings.

Three details separate a component order that works from one that creates callbacks. First, sealing. In a port or a wet quarry, a multi-stage labyrinth with a grease-filled chamber buys years compared with a simple shield. Second, concentricity and wall thickness. Cheap rollers run out of true, and runout becomes belt mistracking. Third, matching the idler spacing to the belt and load — too wide a spacing and the belt sags between idlers, which changes the troughing shape and, on long conveyors, adds running resistance.

If you are an EPC contractor or plant builder assembling a package, buy belt and components from one supplier when you can. Single-source responsibility removes the argument about who owns a tracking problem, and it usually shortens the spare parts list you have to carry.

Buying Rollers, Idlers and Frames Alongside the Belt

Most premature belt failures we are asked to look at start somewhere else on the structure. A mining conveyor rollers supplier that cannot show you the bearing seal arrangement, the shell wall thickness and the shaft tolerance is selling a consumable, not a component. A mining conveyor rollers manufacturer that can show you all three, plus the test method behind them, is usually the one whose idlers are still turning when the belt is replaced for wear rather than for damage.

The practical test is simple: ask for the roller drawing number and the seal type before you ask for the price. If the answer is a catalogue page instead of a drawing, you already know how the next five years will go. We quote conveyor rollers and frames on the same sheet as the belt so the interfaces — pulley crown, idler spacing, transition distance — are fixed by one set of numbers rather than three.

09How Do You Choose a Conveyor Belt Manufacturer You Can Rely On?

This is the question the rest of this guide exists to answer. Our honest position: technical capability can be verified, and so can commercial reliability. Neither can be judged from a website. Here is the sequence we recommend, in the order that saves the most time.

Step 1 — Ask for the belt structure, not the brand

Request a structure table with ply count, fabric type, cover thickness, total thickness, weight per square meter and recommended pulley diameter. A real factory answers within a day; a trader forwards a catalogue page. If the reply arrives with no ply count and no cover thickness, you already have your answer about how the technical conversation will go for the next five years.

Step 2 — Ask what they will refuse to supply

We decline orders when the duty data does not support the requested belt — for example, a customer asking for a thin cover on a conveyor that drops 300 mm granite. Suppliers who never push back are usually optimising for the order, not for your uptime.

Step 3 — Test the quote against a real RFQ

Give two or three suppliers the same data sheet and compare what comes back. Do not compare prices alone; compare the specification behind the price. Our conveyor belt RFQ guide lists the fields that make quotes comparable, and our quality assurance page shows the inspection stages a belt passes before dispatch. If a supplier cannot say what they test and when, assume they test nothing.

Step 4 — Verify the factory, not the office

Video call from the production floor, not the meeting room. Ask to see the press, the calender, the slitting line and the lab. Ask how many production lines run and how many people work there. We have ten lines in Ningbo and more than 200 employees, and we are happy to walk a buyer through them live because that is faster than any brochure. A conveyor belt factory audit checklist turns that call into a structured exercise.

Step 5 — Check the boring numbers

On-time delivery rate, warranty position, response time to a complaint, spare parts availability and whether they will provide a second belt in an emergency. We publish over 95% on-time delivery internally and we work to 30-day standard lead times with 15–20 days for urgent runs, but you should test whatever number a supplier gives you against their own past shipments.

Step 6 — Start small, then scale

Place a modest first order, measure it, then scale. Our low MOQ belt manufacturer article explains why a small first order is a legitimate way to qualify a factory, and how MOQ structures usually work once you move to container volumes.

10Manufacturer, Distributor or Trader: Who Are You Actually Buying From?

All three can be the right answer, depending on what you need. The problem starts when you think you are buying from one and you are buying from another. Our manufacturer vs distributor comparison sets out the trade-offs, and the short version is this: a factory gives you specification control, custom width and splice advice; a conveyor belt distributor gives you local stock, same-day availability and someone who will drive to your site on a Sunday. Large plants with a maintenance budget usually need both, and mature buyers deliberately split spend between a primary factory and a regional stockholder.

How to tell them apart without being rude: ask which machine makes the belt, ask for the factory address, and ask for a phone number at the plant. Then ask a question that only production knowledge answers — for example, what happens to cover adhesion if the press is opened early on a 1,200 mm wide splice. Traders are often perfectly honest about what they are. The risk is the one that is not.

Comparing Conveyor Belt Manufacturers and Conveyor Belt Suppliers on One Sheet

Buyers often collect quotes from several conveyor belt manufacturers and several conveyor belt suppliers and then try to rank them on unit price per metre. That ranking is meaningless unless the specification block is identical. Normalise width, ply or ST grade, cover class, edge construction, splice type, length tolerance, packing and Incoterm first; only then compare the number at the bottom.

A rubber conveyor belt manufacturer and a reseller can both quote the same figure, but only one of them can tell you the batch number of the compound that went into your belt. When we send a quotation we attach the same comparison sheet we use internally, so you can see which lines are ours and which lines are bought in. If you are running that exercise now, our notes on comparing mining conveyor belt manufacturers cover the scoring we would use.

11What Should a Real Quotation Contain?

A quotation that says "EP belt, 1000 mm, price 12 USD/m" is not a quotation; it is a starting position for a dispute. Here is the structure we send, and the structure we recommend you demand from anyone you compare against.

Header data: our name and contact, your reference and date, validity period. Technical column: belt type and carcass, ply count, fabric specification, cover grade with standard, top and bottom cover thickness, total thickness with tolerance, width with tolerance, length, edge construction (moulded or cut), belt weight per square meter, recommended minimum pulley diameter, and maximum recommended working tension. Quality column: tests performed, test method, and whether a mill test report or third-party inspection is included. Commercial column: price per meter, total price, packing method, roll length and maximum roll weight, port of loading, lead time from deposit, payment terms, warranty period, and the validity of the offer.

Then the part most buyers skip: what happens next time. Ask for the price of the second and third order, and for the lead time on a repeat item. A factory that cannot hold a specification across repeat orders is a factory you will have to re-qualify every year. Our factory direct pricing article breaks down what actually moves the number, and the supplier quote comparison guide shows how to normalise offers that look different but are not.

12Price, MOQ, Lead Time and Payment Terms

Nobody likes talking about this and everybody needs to. Our commercial terms are deliberately simple, because obscure terms create disputes that cost more than they save.

If you buy in container volumes, the wholesale conveyor belts route explains how pricing tiers and packing are usually structured for distributors and importers. Our shipping and packaging guide covers how a 1,400 mm roll is protected, strapped and marked so that it arrives without crushed edges, and the supporting payment terms FAQ answers the questions banks ask most often.

13Samples, Testing and Third-Party Inspection

Samples are cheap insurance, and we treat them as part of the technical discussion rather than a courtesy. For a new specification we send belt sections in 2–5 days so your team can check cover hardness, ply adhesion and edge quality by hand. If you are re-sheeting a conveyor after a failure, tell us why the old belt failed and send a section of it. Reading a failed belt tells us more in ten minutes than a specification sheet does in ten pages: worn cover at the skirt line, cracking along a cleat root, or cords exposed at the edge all point at different root causes.

On inspection, you have three tiers. Internal: we test cover tensile strength, elongation, abrasion loss and adhesion on our own lab equipment and issue a mill test report with the shipment. Third party: an inspector nominated by you can attend during production or at the loading point, and we schedule around it. Pre-shipment: dimensions, roll count, marking and packing are verified against the packing list before the container is sealed. If your project requires witnessed testing, tell us at order stage — a test requested after vulcanising cannot change the belt, only the paperwork. Our laboratory test options and factory testing guide list what we can run and what has to be sent out, and the traceability and inspection records page shows how a batch is linked back to its production date and shift. We hold ISO 9001 quality management certification; certificates that apply to a specific project are confirmed in writing at quotation stage rather than promised verbally.

14OEM, Private Label and Custom Dimensions

A large share of what leaves our yard does not carry our name. Distributors and equipment builders order under their own brand, and we support OEM and ODM programmes with logo printing on the belt surface, custom widths, custom thicknesses, custom colours and private label packaging. Two practical constraints are worth knowing before you plan a launch.

First, branding and marking have to be placed so they do not interfere with the splice zone or the load profile. We will ask for your artwork position and confirm the marking strip location on the approved drawing. Second, custom width affects yield from the master roll, and yield affects price. A width that divides efficiently out of a standard slab costs less than one that leaves large offcuts, and we will say so rather than quietly absorb it. Our custom belt drawing and tolerance article explains how we set dimensional tolerances for bespoke widths, and the private label conveyor belt overview covers packaging, barcode and documentation requirements for retail-facing distributors. If you are sourcing a mixed programme that also includes drive belts, the V-belt wholesale guide covers length tolerance matching and branding in the same way for the power transmission side.

15Installation, Splicing and After-Sales Support

A good belt installed badly still fails. We have seen a correctly specified belt destroyed in a week because the splice was cured at the wrong temperature, and we have seen a mediocre belt run for years because the crew did the small things right.

What we offer beyond the belt itself: splice recommendations matched to belt type and site conditions, either vulcanised or mechanical; a plain-language installation sheet; belt storage and handling guidance, since a roll that has been left on the ground and stood on all winter will not track straight; and technical contact through the production and commissioning period. For project work we align delivery with your construction sequence so that belts arrive when the structure can accept them rather than when our press is free. Our service page lists the support steps, and if a problem appears after commissioning our first move is to ask for photographs, belt running hours and the splice record rather than to assign blame. The flame resistant belt verification guide exists because after-sales arguments in this industry are usually about documents, not physics.

16Why Do Belts Fail Early, and Who Should Pay for It?

Early failures cluster into a handful of causes, and separating them is what a warranty conversation should actually be about.

Mistracking is the most common, and its root cause is rarely the belt alone. Off-square structure, failed training idlers, uneven loading, material build-up on a pulley or simply a return idler that has seized will push any belt into the structure. Belt failure at the loading point is second: an impact that exceeds what the carcass can absorb, a chute that discharges onto a stationary belt, or a skirt rubber that has hardened into a scraper. Third is heat and chemical attack, where the wrong compound betrays you over months rather than days. Fourth is splice failure, which usually traces back to preparation, cure temperature, pressure or moisture.

Our position on responsibility is straightforward. If a belt fails because the delivered product does not match the approved specification, that is ours to fix. If it fails because the conveyor was uprated without re-specifying, because the splice was made in the rain, or because an idler was seized for three shifts, we will say so — and we will still help you solve it, because the goal is throughput, not a debate. We honour the warranty period stated on our quotation and our claim policy explains how a claim is evaluated, including the evidence we ask for. Setting up a proper second source before you need one is also sensible risk management, and our second source supplier article covers how to do that without confusing your inventory.

17Total Cost of Ownership: The Numbers Buyers Forget

Purchase price is the easiest number to compare and the least useful one. A belt that costs 15% more but delivers 40% more hours per dollar of maintenance is cheaper, and the arithmetic is not complicated once you list what a failure actually costs.

Build a simple model with five lines. Belt purchase cost amortised over measured service hours. Installation and splicing labour, including crane or winch time. Production lost per hour of unplanned stop, multiplied by the hours a belt change consumes. Cleanup and material recovery after a spill or rip. And the secondary damage — a ripped belt often takes out a pulley lagging, a set of skirt rubber or an idler frame. On most bulk terminals and quarries, line three dwarfs lines one and two by a wide margin, which is why we argue against shaving cover thickness to save a few percent on the invoice.

There is a second, quieter saving: consistency. Standardising on fewer belt specifications reduces the number of items you hold, makes reordering faster and cuts the risk of a maintenance team fitting a belt from the wrong shelf. If you run twenty conveyors across three plants, that standardisation exercise is worth more than any single negotiation. And when you do want volume pricing, the honest way to get it is to consolidate specifications and lengths into one order so the factory can plan one campaign instead of five.

18Frequently Asked Questions

What is your minimum order quantity, and can we start with a trial order?

Our minimum is about 50 m per specification, which is low enough for a genuine trial. We would rather you run a small order on one conveyor, measure the hours, and then scale than place a container order based on a catalogue page. Trial orders are also the fastest way to test our documentation, packing and communication, which matter as much as the belt itself.

How long is your lead time, and can you handle an emergency?

Standard lead time is roughly 30 days from deposit and approved drawing. Urgent orders can run in 15–20 days when the press schedule allows, so tell us your shutdown window at enquiry stage rather than after the order. Samples take 2–5 days. If a conveyor is down and you need a belt before a scheduled maintenance window, say that in the first email — it changes how we sequence production.

Do you support OEM, private label and custom specifications?

Yes. We produce under customer brands with logo printing, and we build to custom width, thickness, colour, cover grade and ply count. Send an approved drawing or a sample plus the duty data and we will confirm the tolerances before production. We do not put a customer logo on a belt until the marking position and artwork are approved on the drawing.

What payment terms do you accept?

T/T with 30% deposit and the balance of 70% before shipment, or L/C. For repeat customers we discuss terms that reflect the actual order pattern. If you plan to use an L/C, share the draft wording with us during quotation so that any point requiring correction is resolved before the bank charges you for an amendment.

Can we arrange third-party inspection before shipment?

Yes. An inspector appointed by you is welcome during production or at pre-shipment, and we will schedule around the inspection so that the belt is available in its final form rather than half-built. Witnessed testing needs to be agreed at order stage, because a test requested after vulcanising can only document what was made, not change it.

Which belts do you make in-house, and how do you control quality?

We run ten production lines in Ningbo — eight for fabric carcass belts and two for steel cord — covering rubber conveyor belting, PVC and PU lightweight belting, V-belts and timing belts, plus idlers, rollers and pulleys. Quality control runs from incoming rubber and fabric checks, through in-process checks on cover thickness and ply alignment, to final dimensional checks and laboratory tests on cover strength, elongation, abrasion loss and adhesion. We operate an ISO 9001 quality management system and maintain over 95% on-time delivery across more than 1,500 industrial customers. Any specific certificate or test value for your project is confirmed in writing against the approved drawing.

How do we contact you about a requirement?

Email us at sales@sinoconve.com with the belt width, material handled, tonnes per hour, centre distance, lift, pulley diameters, belt speed and temperature range — or just send the existing belt nameplate and a photo. If your information is incomplete, we will ask the missing questions. For wider background on our plant, customers or compliance paperwork, the FAQs and technical blog answer most first-round questions before you spend time on an enquiry.
