A chain plate belt, also called a plate link, hinged steel or slat belt, is a conveyor of steel plates carried on rods and chains, used where products are heavy, sharp, hot or need to drain. Because plate pitch and chain pitch are two different numbers, we confirm both — with the sprocket — on your drawing before production.
Chain Plate / Plate Link Belt documents
Documents from our Document Library: the dimensions and options to compare with your current belt, and how the belt is made and inspected at our factory in Ningjin, Shandong.
Hole pattern, pins and the sprocket are built to your approved drawing.
Watch how a chain plate belt is made and inspected at our Ningjin factory.
Plate pitch is the spacing of the plates. Chain pitch is the pitch of the chain that carries them. We confirm both, with the sprocket, on your drawing before production.

Real photos from our Ningjin factory. Every formal belt passes final inspection against your drawing before packing.
Real orders, with customer details withheld.
Repeat order, distributor, Southern Africa. The distributor re-ordered a plate belt we had built for them before, made to the same drawing. Plates with bent edges are bolted to bent attachment plates on the chain, and the 40Mn chain was sourced to specification. Every dimension was photographed, and the inspection report and material documentation were sent before shipment.
| Width | 1,230 mm |
| Plates | Carbon steel, 3 mm, bent edge ≈ 12.7 × 12 mm |
| Chain | 38.1 mm pitch, roller Ø 22.23 mm, inner width 25.4 mm |
| Chain plates | 3.25 × 17.2 mm, pin Ø 6 mm, 40Mn |
| Fixing | Plates bolted to bent attachment plates, 3 holes |
| Finish | Oiled, packed clean and dry |
The questions we hear most, answered from how we actually build and check this belt.
Plates are laser cut and punched in our own workshop in Ningjin, Shandong, and round bar is drawn in-house. Selected stainless chains are assembled on automatic equipment; other chain is sourced to specification and checked.
Plate pitch and chain pitch are two different numbers. We measure and specify them separately on the drawing, so plates are not built to the chain pitch by mistake.
Chain type, attachments and sprocket profile are confirmed together before quoting. Sprockets are made by specialist partners to our specification, and we check the finished parts.
Hole diameter, spacing and layout are set on the drawing, and the first plates are measured before full production.
Plate edges are deburred and checked by hand before assembly. Every rod end is washer welded or cotter-pinned and checked on the semi-finished belt.
Plate alignment, pitch and chain are checked on the assembled belt before packing.
We draw wire and round bar in-house, and each incoming batch is checked for composition and hardness. Buyers often ask for a mill test report (MTR) or mill test certificate (MTC). Tell us which documents your order needs and we confirm them in the quotation.
Clean and dry, in waterproof film and plywood or fumigated wooden cases, with an English shipping list, for sea, air or rail.
It does not go to packing. It is recorded, reworked or remade, and inspected again. A 100% final inspection is not a zero-defect or lifetime guarantee, but you see measured photos and the inspection report of your own belt before shipment.
Lead time is confirmed per order in the quotation. Progress updates are agreed for each order, covering material and tooling status.
A conveyor belt made of steel plates mounted on rods and carried by side chains, also called a plate link belt.
No. Plate pitch (25.4–63.5 mm) and chain pitch (25.4–76.2 mm) are separate values, and both are confirmed on the drawing.
Yes. Plates can be solid or perforated; hole diameter, shape, spacing and pattern are set per project.
From 300 to 4000 mm, or to your drawing.
With welded washers or cotter pins.
Yes. Third-party inspection is supported on request, and customer factory visits are welcome.
Buyers often ask for a mill test report (MTR) or mill test certificate (MTC). Each incoming batch of wire and rod is checked against steel-mill material documentation, with spectral and hardness testing. Tell us which documents your order needs and we confirm them in the quotation. Read more about material documentation.
