Conveyor belts move product through nearly every stage of modern production. Yet two lines carrying similar products can require completely different belts. Belt material, belt surface, open area, strength, and cleanability all shape how a belt performs once it’s running.
Understanding the main types of conveyor belts helps engineers and plant managers match the belt to the process. This guide covers how belt conveyors work, the most common conveyor belt types used in material handling systems, and where metal designs such as flat wire and wire mesh belts fit best.
A belt conveyor system runs a continuous loop of belting around a drive pulley at one end and tail pulleys at the other. An electric motor, usually paired with a gear motor or reducer, powers the drive. Bend pulleys help route the belt and maintain wrap around the drive, while the conveyor bed supports the belt between terminals.
Belt tracking is critical. A belt that drifts to one side can wear edges, damage product, and interrupt material flow. Positive drive designs, where sprockets engage the belt directly, help the entire belt run straight and reduce tracking adjustments.
Conveyor belts differ from power transmission belts, which drive machinery rather than carry product. In belt conveying systems, the belt itself becomes the product-handling surface.
Flat belt conveyors are among the most widely used conveyor systems in manufacturing environments. A continuous flat belt, often made from natural or synthetic materials such as polyester, provides a smooth, flat surface for small, soft, or irregularly shaped items. These systems appear frequently in packaging lines, distribution centers, and assembly lines, including slow assembly lines where workers handle parts directly on the belt.
Modular belt conveyors use interlocking segments rather than a single continuous belt. Modular plastic belts are common in packaging equipment and some food applications. Damaged sections can be replaced individually, and many modular belt designs can navigate curves.
A cleated belt includes raised sections along its length. Each cleat stands perpendicular to the belt surface, helping inclined conveyors move loose materials up steep inclines without rollback. Cleats also maintain spacing between items. Some incline applications use a rough surface belt instead to improve grip.
Roller bed conveyor belts run over a series of rollers rather than a slider bed. The rollers reduce friction, which helps move heavier loads over longer distances. Airport baggage handling is a familiar example. Roller conveyors without a belt, including pallet conveyors and systems with motorized rollers, are often used for boxes, totes, and pallets.
Curved belt conveyors guide product around corners while maintaining orientation and spacing. Wire Belt Flex-Turn® conveyors are available in 45° and 90° configurations, with some models available in 180°, helping facilities fit conveyor solutions into tight layouts.
Bulk conveyor belts carry loose bulk material such as grain, aggregate, or waste materials. Troughed belts cradle product for heavy-duty transport, and enclosed conveyors help contain dust. Magnetic conveyor belts separate or move ferrous parts, and screw conveyors or an elevator belt with buckets are often chosen when bulk material handling involves vertical movement or highly abrasive materials.
Metal belts fill a distinct role among different types of conveyor. Stainless steel construction handles high temperatures, freezing conditions, and repeated washdowns, while open designs let air, heat, and liquid pass through the belt.
Flat wire belts are built from flattened wire strips joined by round rods. Flat-Flex® has more than 85 years of trusted performance, with up to 86% open area, very low belt mass, and positive drive for accurate tracking. Small diameter end and drive rolls support tight transfers. Standard material is 302 stainless steel, with 316 stainless steel and other materials available across more than 5,000 configurations. C-CureEdge® technology, available for most Flat-Flex® belts, helps prevent edges from catching and tangling.
Ladder-Track™ is a simple ladder-style belt most commonly found in bakeries. It is lightweight, positively sprocket driven, and offers a flat, uniform surface for gentle handling in straight-running applications. High tensile rods resist permanent distortion, and the belt is easy to assemble and disassemble.
TC-327™ is engineered specifically for tortilla processing and cooling.
Wire mesh belts are known for withstanding extreme temperatures. Grid designs take a more open approach while still supporting small items.
Compact-Grid® supports smaller and more delicate products. The 10 mm mesh offers approximately 70% open area, and the 15 mm mesh offers approximately 73%. With no welded joints where residue can build up, it works well for snack foods, crackers, chips, and frying.
Versa-Link® serves light- to medium-duty food processing. Patented Advanced Link Rods allow joining in as little as 30 seconds without special tools, and Forged Edge Technology creates a flush, weld-free edge. Open area reaches up to 81%.
Eye-Flex® is a heavy-duty modular metal belt built for heavy loads and rugged operation. Drive options include cage rollers, positive drive sprockets, and chain edge drive. Spring spacer configurations improve dimensional stability in heating or freezing, and flights and side guards can be added.
Sanitary conveyors are designed for frequent cleaning, and they often rely on flat wire belts for open access to product-contact surfaces. Flat-Flex®, Compact-Grid®, and Versa-Link® are USDA Accepted, and Flat-Flex® and Compact-Grid® feature clean-in-place designs. Good drainage and fewer catch points support sanitation programs built around HACCP and FSMA requirements.
Material handling requirements should drive the decision. Consider:
Matching these factors improves material handling efficiency and operational efficiency over the life of the line.
No single belt fits every process. With more than 100 years of industry knowledge, Wire Belt Company helps customers evaluate product, load, temperature, and layout before recommending a configuration. Calls are answered by real people, and our Technical Sales Specialists work directly with your team. Contact our team to discuss your conveyor belt applications.
Common types include flat belts, modular belts, cleated belts, roller bed belts, and metal belts. Metal belts are preferred where heat, cold, airflow, or frequent washdowns are part of the process.
Flat wire belts use flattened strips joined by rods, creating a very open surface with low belt mass. Grid and mesh belts use a tighter pattern that supports smaller products while still allowing drainage.
Cleated belts work well when inclined conveyors need to move loose materials or keep items evenly spaced. The cleats prevent product from sliding back on steep inclines.
Eye-Flex® is designed for rugged, high-load applications and offers multiple drive options. Talk with a Technical Sales Specialist to confirm the right configuration for your load.
Look for stainless steel construction, open design, good drainage, and easy cleaning access. USDA Accepted belts such as Flat-Flex®, Compact-Grid®, and Versa-Link® are built for these environments.
Advanced Link Rods allow Versa-Link® to be joined in as little as 30 seconds with no special tools, helping maintenance teams return lines to production quickly.
