Manufacturing Process
How This Product Is Made
1Cutting steel wire to length based on nominal size and pitch
2Welding each link end to form a continuous chain with consistent joint strength
3Straightening and sizing the chain after welding to maintain dimensional accuracy
4Applying surface finish—self-color, zinc plating, or hot dip galvanizing—based on order
5Proof load testing on production batches to verify strength and joint integrity
6Marking working load limit and chain type on the chain body for traceability
Quality Control
Quality Control On Every Batch
- Proof load testing on production batches to confirm minimum breaking force
- Dimensional tolerance check against published size table for pitch and width
- Visual inspection of welds for cracks, porosity, or incomplete fusion
- Breaking strength validation to ensure 2.5:1 design factor is met
- Surface finish thickness and adhesion checked for zinc and galvanizing layers
- Material Test Certificate to EN 10204 3.1 supplied with orders
Documentation
Certification And Documentation Supplied
- Material Test Certificate to EN 10204 3.1 supplied with orders
- Working load limit and chain type stamped on the chain body
Customisation
Customisation Options
- Custom tonnage stamping on the chain body for traceability
- Private label and OEM marking available for brand-specific packaging
- Finish to order: self-color, zinc plated, or hot dip galvanized
- Custom link style (straight or twist) based on application needs
- Packing configuration tailored to carton count and pallet pattern for warehouse or retail use

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 |
|---|---|
| Standard welded chain without DIN specification | DIN5685A/C chains have defined pitch, width, and strength ratios, ensuring interchangeability and predictable performance |
| Forged chain | Welded chain is lighter and less expensive but lacks the impact resistance of forged chain; not suitable for dynamic or high-impact loads |
| Galvanized chain with no DIN standard | DIN5685A/C chains have certified dimensions and strength, while non-standard galvanized chains may vary in load capacity and geometry |
| Overhead lifting chain | This chain is not rated for overhead lifting and lacks the 4:1 design factor required for lifting applications |
Use Guide
How To Use And Inspect DIN5685A
- Do not exceed the stamped working load limit under any circumstances
- Use only in non-lifting applications such as tie-downs, barriers, or mechanical linkages
- Inspect the chain regularly for weld defects, corrosion, or deformation
- Avoid sharp bends or side loading that can stress the welded joints
- Choose twist link for reduced snagging in moving or dragging applications
- Replace the chain if the surface finish is damaged or the marking is no longer legible

Answers
DIN5685A FAQ
Is this chain suitable for overhead lifting?
No. This chain is not rated for overhead lifting and does not meet the 4:1 design factor required for lifting applications. It is intended for general-purpose, non-lifting use only.
What is the design factor for this chain?
The design factor is 2.5:1, meaning the minimum breaking force is 2.5 times the stated working load limit. This is appropriate for non-lifting applications.
Can I get a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order. It confirms the material composition and mechanical properties of the chain.
What finishes are available?
Available finishes include self-color, zinc plated, and hot dip galvanized. Choose based on environmental exposure and corrosion resistance needs.
Can I order custom link style or length?
Yes. Both straight and twist link styles are available. Custom lengths can be built to order with specified end fittings or splicing.
How is the chain packed for export?
Standard packing is plastic reel + carton + steel pallet. We can configure carton count and pallet pattern to match your warehouse or retail requirements.
What sizes are available?
The chain is available from 2 mm to 13 mm nominal size, with corresponding working load limits from 20 kg to 800 kg. Full size table is available in the product data sheet.
