Conveyor belts fall into a handful of core types, defined either by how the belt is built or by the material it is made from. The main construction types are flat, modular plastic, cleated, and wire mesh belts. The main material types are rubber, PVC, polyurethane, and metal. Which one is right depends on the weight and shape of the load, the operating temperature, hygiene requirements, and whether the belt runs flat or on an incline.
Below is a practical breakdown of the belt types used in industrial material handling, how their materials differ, and how to match a belt to the job. The same principles apply whether the belt feeds a production line or moves scrap into a baler or compactor.

Conveyor belt types by construction
Conveyor belts are grouped by construction into four everyday types: flat belts, modular plastic belts, cleated or incline belts, and wire mesh belts. Each handles a different combination of load, angle, and environment.
Flat belts
Flat belts are the most common type. A continuous loop of rubber, fabric, or thermoplastic runs over rollers or a slider bed to move light to medium loads horizontally. They are inexpensive, easy to install, and versatile across the food, automotive, and packaging industries. The limitation is angle: loose or unsecured items can slide off once the belt climbs, so flat belts stay near horizontal.
Modular plastic belts
Modular belts are built from interlocking plastic modules made of polypropylene, polyethylene, or acetal. Because a damaged module can be swapped out on its own, these belts are durable and cheap to maintain, and they handle sharp edges, wet conditions, and washdown well. That makes them a standard in food processing, beverage, and heavy-duty handling. Modular belts also turn corners and change elevation more easily than a single-piece belt.
Cleated and incline belts
Cleated belts add raised ribs, walls, or buckets across the surface so material stays in place on a slope. They are the answer whenever a line has to lift product between two heights, for example loading a hopper, feeding an elevated machine, or carrying loose material up an incline. Sidewall corrugated belts extend the same idea to steep angles, close to vertical, without spilling the load.
Wire mesh and metal belts
Wire mesh belts are woven from stainless or carbon steel wire, leaving an open surface that lets air, heat, and liquid pass through. They suit drying, cooling, baking, and washing lines, and they tolerate temperatures that would destroy a rubber or plastic belt. Solid metal belts add high tensile strength and corrosion resistance for the most demanding heat and abrasion duties.
Conveyor belt materials and where they fit
Belt material decides traction, temperature range, hygiene, and chemical resistance. Four materials cover most industrial use: rubber, PVC, polyurethane, and metal. The table below summarises how they compare.
| Material | Key properties | Common uses |
|---|---|---|
| Rubber | High traction and abrasion resistance, flexible, wide temperature range | Bulk handling, mining, recycling, aggregates, construction |
| PVC | Lightweight, smooth, easy to clean, low cost | Light assembly, packaging, general food handling |
| Polyurethane (PU) | Strong wear resistance, resists oil and grease, hygienic and non-porous | Food contact, pharmaceutical, packaging |
| Metal / wire mesh | Very high heat and corrosion resistance, open surface for airflow or drainage | Drying, cooling, baking, high-temperature and heavy-duty lines |
Rubber remains the workhorse by volume. Multi-ply rubber belts with a polyester carcass carry the majority of aggregate, mining, and bulk material, which is why they show up in scrap and recycling yards. PVC and PU take over wherever hygiene and easy cleaning matter more than raw toughness, and metal belts handle the temperature extremes the other three cannot.
Comparing the main belt types
The quickest way to shortlist a belt is to match its strength against the job. This comparison covers the four construction types side by side.
| Belt type | Best suited for | Main limitation |
|---|---|---|
| Flat belt | Light to medium loads on horizontal runs | Loses grip on inclines |
| Modular plastic | Washdown, sharp edges, curves and elevation changes | Higher cost than a plain flat belt |
| Cleated / incline | Lifting loose material between heights | Cleats can trap fine debris |
| Wire mesh / metal | Heat, drying, cooling and drainage | Not suited to small or fine parts |
Conveyor belts in metal and recycling operations
In a recycling or scrap operation, the conveyor is what keeps a baler or compactor fed at a steady rate. Heavy rubber or steel-reinforced belts move cardboard, plastic, and metal offcuts from the sorting area to the machine, so the belt has to survive abrasion, sharp edges, and constant loading. Getting the belt right here is a throughput question: a belt that slips or tears stalls the whole line.
This is why belt selection sits alongside the machine itself when planning a line. For a wider view of how conveying, sorting, and baling fit together, see our guide to industrial metal recycling, and browse the conveyor systems we build for feeding balers and compactors.
What types of conveyor belts are used in automotive manufacturing?
Automotive plants use several belt types depending on the station. Flat and modular plastic belts move light parts along assembly and quality-control lines, roller and chain conveyors carry heavier components such as engine blocks and chassis sections, and steel or piano-hinged belts handle metal stamping scrap and hot, heavy parts. Twin-belt or sandwich conveyors grip parts from both sides to keep them stable on inclines. The common thread is matching belt strength to part weight and to the abrasion of metal contact.
How to choose the right conveyor belt
There is no single best belt. The right choice comes from working through a few concrete factors before you look at price.
- Load: weight, size, and whether items are boxed, loose, or bulk.
- Environment: dry, wet, dusty, oily, or subject to washdown.
- Temperature: the cover material sets the safe operating range.
- Hygiene: food and pharmaceutical lines need PU or PVC and easy cleaning.
- Angle: any incline points toward cleated or modular belts.
- Maintenance: modular belts are repaired module by module, single-piece belts as a whole.
Work through those in order and the shortlist usually narrows to one or two belts. When it does not, the material table above is the tie-breaker.
Frequently asked questions
What is the most common type of conveyor belt?
The flat belt is the most common type across industry. It is inexpensive, simple to install, and flexible enough for light to medium loads on horizontal runs, which covers a large share of everyday material handling. By material volume, multi-ply rubber belts are the most widely used in bulk and heavy-duty work.
What is the difference between rubber and PVC conveyor belts?
Rubber belts offer higher traction and abrasion resistance and handle a wider temperature range, so they dominate bulk, mining, and recycling work. PVC belts are lighter, smoother, and easier to clean, which suits packaging and general food handling. In short, rubber is chosen for toughness and PVC for hygiene and low weight.
Which conveyor belt material is best for food processing?
Polyurethane is the usual choice for direct food contact because it is non-porous, resists oils and fats, and cleans easily. PVC also serves lighter food-handling duties. Both beat rubber on hygiene, while wire mesh belts handle baking and cooling stages where airflow through the belt matters.
What temperature can a conveyor belt handle?
The safe range depends entirely on the cover material. Standard rubber and PVC belts work in everyday ambient conditions, specialist high-heat rubber compounds extend that range, and metal or wire mesh belts handle the highest temperatures found in drying, baking, and heat-treatment lines. Always match the belt rating to the hottest point on the line.
