Metal conveyor belts built to your drawing
The belt families where drum geometry, pitch and drive matching decide whether the line runs correctly after installation. Tap "Add to RFQ" to collect what you need; full specifications in mm and inch are on each product page.
FlagshipSpiral Freezer Belt
For spiral freezers and turning conveyors. Turn ratio, drum geometry and edge structure are reviewed together.
Custom sizes on request
Self-Stacking Belt
Each tier rests on the side stack plates of the tier below, so the belt forms its own supporting stack.
Custom sizes on request
Side Driven Belt
Side-driven, side-guided belt for spiral and turning systems. Stainless side links with a polymer or all-stainless carrying surface.
Custom sizes on request
Spiral variantSpiral Freezer Belt (Small Turning Radius)
Variant of the spiral freezer belt for tight turns where the drum leaves little room.
Custom sizes on request
Eye Link Belt
Open eye-link structure on cross rods, with reinforcement, flights or side plates as the project needs.
Custom sizes on request
Flat Wire / Honeycomb Belt
Flat strips on cross rods for an even, open carrying surface in baking, cooling and processing lines.

How YIYI Mesh Belt builds your belt
In our own workshop, from raw wire to the finished belt. Each step is checked before the next.
1Wire and round-bar drawing
In-house stainless wire drawing, and round-bar drawing from 12 mm raw material.
2Spiral forming
First piece checked before the batch runs.
3Belt assembly
Assembled and straightened to your drawing.
4Robotic welding
Rod-to-link welds by robot; 9 robots in the workshop.
5Inspection
Every belt measured before packing.
Selected specialist processes, such as some chains, sprockets, pickling, electropolishing and heat treatment, are sourced to the project specification and checked against finished-product requirements.

How do I order a custom metal conveyor belt to my drawing?
Send your drawing, or the dimensions you have, with the application and quantity. YIYI Mesh Belt confirms the drawing with production suggestions, makes a trial piece when needed, and starts production only after your approval.
Can you make a replacement conveyor belt from an old belt without a drawing?
Yes. Photos and measured dimensions support a preliminary quotation; for formal replacement we use the physical old belt, any drawings and the equipment information, because a worn belt can differ from the original design.
How do I measure an old metal conveyor belt?
Measure pitch with a tape over 10 pitches and divide by 10, wire and rod diameter with a caliper in three places, then record the edge type, overall width and, for spiral belts, turn direction and drum diameter. The spiral page shows the four steps with photos.
Which metal conveyor belts does YIYI Mesh Belt manufacture?
Spiral freezer belts, self-stacking belts, side driven belts, small radius spiral belts, eye link belts and flat wire (honeycomb) belts, plus balanced and compound weave, chain-driven and other metal belts, with matched sprockets and spare parts.
Do you provide material documentation for stainless steel conveyor belts?
Yes. Incoming wire and rod are checked for composition with an alloy analyser, material is traceable to each order, and material documentation can be provided for your order.
What happens after I place an order?
Drawing approval with suggestions, a trial piece when you send a sample, production after your approval, progress updates agreed for each order, an order record of every requirement, a turning or running test where relevant, and measured photos plus an inspection report before shipment.
What is the lead time for a metal conveyor belt?
Lead time is confirmed with each quotation. We keep regular raw-material stock and draw stainless wire and round bar in-house; finished spiral freezer belt capacity is approximately 350–400 m per day. Capacity is not a lead time.
What does 100% final inspection mean?
Every completed formal belt is inspected before packing, including pitch, width, length, flatness, welds, structural dimensions and drive matching where applicable. It is not a zero-defect or lifetime guarantee.
