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 |
|---|---|
| Grade 43 transport chain | Grade 70 offers higher tensile strength and better impact resistance, suitable for heavier loads and dynamic applications |
| EN 818-2 Grade 80 chain | Grade 70 has lower strength but is more cost-effective; Grade 80 offers higher working load limits but at a higher price |
| Galvanized chain | Yellow chromated zinc plating offers better corrosion resistance than standard galvanizing in salt and moisture environments |
| Overhead lifting chain | Not rated for overhead lifting; Grade 70 transport chain is designed for tie-down and towing, not vertical lifting |
Use Guide
How To Use And Inspect Grade 70 Short Link Transport Chain ASTM A413
- Never exceed the stamped working load limit on the chain
- Inspect the chain before each use for wear, deformation, or surface damage
- Avoid side loading or sharp bends that can reduce strength and cause failure
- Use only with compatible hardware such as shackles and tensioners
- Replace the chain if the link shows visible stretching, cracks, or if the finish is compromised
- Store in a dry, covered area to maintain the zinc plating and prevent rust
