Manufacturing Process
How This Product Is Made
1Cutting of low carbon steel wire to specified diameter
2Forming of links into long-link shape using precision dies
3Welding of each link joint with consistent bead profile
4Heat treatment to relieve welding stress and improve ductility
5Surface finishing by zinc plating or hot dip galvanizing as ordered
6Proof load testing on production batches
7Packaging on plastic reels, then into cartons and steel pallets
Quality Control
Quality Control On Every Batch
- Proof load test conducted on each production batch at minimum a proportion of the working load limit
- Dimensional inspection of inside length and width against published values
- Visual and weld integrity check for consistent joint quality
- Surface finish thickness verified for zinc plating and galvanizing
- Working load limit stamped on each chain section for traceability
- Material Test Certificate to EN 10204 3.1 supplied on request
- Third-party inspection accepted at the Qingdao warehouse before shipment
Customisation
Customisation Options
- Custom tonnage stamping on chain links
- Private label and OEM marking available
- Finish selection: self-color, zinc plated, or hot dip galvanized
- Custom packaging configuration including carton and pallet layout
- Chain length or reel size built to a drawing or specification

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Short link chain | Long link chain reduces surface wear and snagging in restraint systems but has lower tensile strength per unit length |
| Galvanized chain from a third-party supplier | Direct manufacturer supply ensures consistent NACM2010 compliance and traceable material testing |
| Non-welded chain | Welded construction provides stronger joint integrity and consistent alignment in repeated use |
| Overhead lifting chain | This chain is not rated for overhead lifting and lacks the design factor and certification for that use |
Use Guide
How To Use And Inspect Straight Link Coil Chain - NACM2010
- Do not exceed the working load limit stamped on the chain
- Inspect the chain before each use for weld cracks, deformation, or finish loss
- Use only in static or low-motion restraint applications, not for overhead lifting
- Choose finish based on environment: zinc plating for indoor, galvanizing for outdoor or wet areas
- Keep chain free from debris and lubricate if needed to prevent seizing
- Replace chain if the link shows visible deformation or the stamping is no longer legible
- Store on plastic reels to prevent kinking and surface damage
