Different from balanced weave belt consisting of alternating left-hand and right-hand spiral coils chain link conveyor belting is constructed by unidirectional coils. For a friction driven belt, the belt features alternating sections of left-hand then right-hand. To counteract the tracking issues caused by the unidirectional coil pattern, cross rods are inserted across the belts - one is right-hand woven and the other is right-hand woven.

Apart from the standard rod reinforced chain link belt, there is also duplex Link Belt With Rod Reinforced, which has double interwoven spiral wires. This duplex version chain belt has smaller open area and more strength. Compared with universal chain link belt, rod reinforced chain link belt has wider applications because of its relatively heavy load ability, open area and economical cost.

Edge Availability

chain link conveyor belt are available in different edge styles including welded, knuckled and chained. Other special edge finish is available on request.

Chain Link Conveyor Belt Welded Edge Finish Detail

Welded Edge

At the belt edges the coil wires are looped together and welded. This is the most common and economical edge finish. This type of edge finish allows for relatively smooth finish to the belt edge and is the most economic version of this belt style.

Chain Link Conveyor Belt Knuckled Edge Finish — U-Shaped Interlocked Wire Ends

Knuckled Edge

The end of each coil wire is bent back into a ‘U’ shape and then interlock with the adjacent coil. The ‘U’ form is then closed securely to form a permanent link with the next coil. This formation also allows greater flexibility of the belt edges and minimises stress build up at these positions.

Chain Link Belt Chain Edge with Side Roller Chain Drive

Chain Edge

Along with the mesh edge finishes these meshes can be driven by side chains using cross rods which are located through the mesh coils and then through chains at the edges of the mesh.

Chain Link Conveyor Belts - Frequently Asked Questions

Common questions about chain link conveyor belts, conventional weave belts, and wire mesh conveyor belts for drying, cooling, and food processing

Q1. What is a chain link conveyor belt?

A chain link conveyor belt — also known as a conventional weave belt or conventional mesh belt — is a wire mesh belt made of interlocked spiral wire coils forming a flat, open mesh structure. Individual elements consist of alternating right-hand and left-hand round wire spirals joined across the belt width.

For friction-driven belts, the coil sections alternate left-hand then right-hand to counteract lateral tracking drift. Rod-reinforced versions insert cross rods through the interconnecting coils to add tensile strength and dimensional stability.

The open mesh structure allows excellent airflow through the belt surface, making chain link belts well suited to processes that rely on air or fluid circulation:

• Drying ovens — heated air circulates freely through the mesh, improving drying efficiency and reducing energy consumption.
• Cooling conveyors — chilled air flows through the open structure to rapidly lower product temperature.
• Frying facilities — oil drains freely through the belt; stainless steel resists cooking oils and repeated cleaning cycles.
• Annealing furnaces — high-temperature alloy grades rated to 1150°C are available for metal heat-treatment applications.

Compared with other wire belt types, chain link belts offer the most economical structure for light-duty conveying applications.

Q2. What are the three types of chain link conveyor belts?

PFM Screen manufactures three chain link belt configurations:

• Standard chain link belt (without rod reinforced) — the simplest and most economical design. Lateral coil wire pitches range from 5.08 mm to 25.4 mm, combined with a variety of wire diameters and longitudinal pitches. Best suited to very light loads and low-speed conveying where minimal belt strength is required.

• Rod reinforced chain link belt — cross rods are inserted through the interconnecting spiral wires across the full belt width. The rods add tensile strength, improve tracking stability, and allow the belt to carry greater loads than the standard version. Typical specifications: lateral coil pitch 16.93–25.4 mm, coil wire diameter 2.03–3.25 mm, cross wire pitch 16.93–19.05 mm, cross wire diameter 2.64–4.06 mm. This is the most widely used chain link belt configuration due to its improved load capacity and competitive cost.

• Chain duplex link belt with rod reinforced — uses double interwoven spiral wires with cross rod reinforcement. The duplex construction produces a smaller open-mesh area and provides greater tensile strength than the single-coil rod reinforced version. Typical specifications: lateral coil pitch 5.08–8.47 mm, cross wire pitch 10.16–19.05 mm. Preferred where a higher mesh density is required alongside cost efficiency.

Q3. What edge styles are available for chain link conveyor belts?

Three edge finishes are available for chain link belts:

• Welded edge — coil wire ends at the belt edges are looped together and welded. This is the most common and economical edge finish, providing a relatively smooth, stable edge suitable for most conveyor system configurations. Welded edges are specified for the majority of drying and cooling applications.

• Knuckled edge — each coil wire end is bent into a U-shape and interlocked with the adjacent coil, then closed securely to form a permanent link. Knuckled edges allow greater flexibility at the belt margins and minimise stress concentration at the edges during operation. Preferred where edge fatigue under repeated flexing is a concern.

• Chain edge — cross rods extend through the mesh coils and connect to roller chains running along the belt edges, enabling positive chain-driven conveyor systems. Chain-edge belts deliver accurate belt speed control and can accommodate side and centre baffles to prevent product spillage during conveying.

Q4. What materials are available and what temperature can chain link belts withstand?

Chain link belts are available in a range of wire materials. The table below shows each material's maximum continuous operating temperature:

Wire Material	Max. Operating Temperature (°C)
Carbon Steel	550
Galvanised Mild Steel	400
Chrome Molybdenum (3% Chrome)	700
304 Stainless Steel	750
321 Stainless Steel	750
316 Stainless Steel	800
316L Stainless Steel	800
314 Stainless Steel	1120
37/18 Nickel Chrome	1120
80/20 Nickel Chrome	1150
Inconel 600	1150
Inconel 601	1150

For food processing and general industrial use, 304 or 316 stainless steel is most commonly specified. For high-temperature furnace applications such as annealing and heat treatment, 314 stainless steel, 37/18 Nickel Chrome, 80/20 Nickel Chrome, or Inconel alloys are required. Please specify your required material grade when requesting a quotation.

Q5. What industries and applications are chain link conveyor belts used in?

Chain link belts are suited to light-duty conveying where the open mesh structure delivers a direct process advantage. Key application areas include:

• Drying ovens — the open mesh allows heated air to circulate freely through the belt and around the product surface, improving drying efficiency and reducing energy consumption. Widely used in food product drying, ceramic component drying, and industrial parts drying.

• Frying facilities and food processing lines — stainless steel chain link belts withstand cooking oils, high operating temperatures, and repeated food-grade cleaning cycles. The open mesh structure allows oil to drain freely below the belt during operation.

• Cooling conveyors and frosters — chilled air or refrigerant flows through the open mesh to rapidly lower product temperature. Used in meat processing, confectionery, frozen ready meals, and baked goods production lines.

• Cleaning machines and washing lines — the open mesh allows wash water, detergent, and rinse water to penetrate fully around the product during automated washing and rinsing cycles. Common in automotive component cleaning and food-grade wash systems.

• Annealing furnaces and heat treatment — high-temperature alloy grades (314 SS, Inconel 600/601, 80/20 Nickel Chrome) rated to 1120–1150°C are used in metal annealing, normalising, and continuous heat-treatment furnace systems.

• Refrigeration and frozen food facilities — 304 and 316 stainless steel chain link belts are used for low-temperature conveying in cold stores and IQF (individual quick freeze) tunnel systems.

Q6. How do I specify and order a custom chain link conveyor belt?

The required specification parameters vary by belt type. Downloadable enquiry forms for each belt type are available on this page.

For standard chain link belts (without rod):
Provide belt width, working length, lateral coil pitch (A, mm), longitudinal coil pitch (B, mm), and wire diameter (C, mm).

For rod reinforced chain link belts:
Provide belt width, working length, lateral coil pitch (A, mm), coil wire diameter (B, mm), longitudinal cross wire pitch (C, mm), and cross wire diameter (D, mm).

For all belt types, also specify:

• Edge style — welded, knuckled, or chain edge.
• Wire material — and required maximum operating temperature.
• Drive type — friction-driven or chain-driven.
• Baffles — whether side baffles, centre baffles, or other special features are required.
• Quantity and lead time — required belt quantity and delivery timeframe.

Custom specifications outside the standard size ranges listed are accepted. Contact PFM Screen at [email protected] or via WhatsApp at +86-15369679157 for a quotation.

Q7. How does a chain link belt compare to a balanced spiral conveyor belt?

Both belt types are built from interconnected spiral wire coils but differ in construction, load capacity, and cost:

Feature	Chain Link Belt	Balanced Spiral Belt
Coil direction	Unidirectional sections, alternating L/R groups	Fully alternating L/R coils throughout
Load capacity	Light to medium (rod reinforced / duplex)	Medium to heavy
Tracking stability	Good (with rod reinforcement)	Excellent (inherent by design)
Typical pitch range	5.08–25.4 mm lateral coil pitch	Wider range; tighter mesh options
Cost	Lower	Higher
Best suited to	Light-duty drying, cooling, frying, washing	Medium-to-heavy loads, high-speed lines

If your application involves light-duty conveying with low product weight and an economical wire belt solution is a priority, a chain link belt is the appropriate choice. For heavier loads, higher conveying speeds, or applications requiring tighter dimensional stability, a balanced spiral belt or compound weave belt should be considered.
