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 80 Alloy Chain NACM2010 | Grade 70 AS4344 has lower strength but is specifically designed for transport restraint with AS4344 compliance, while Grade 80 is for general industrial use and may not meet transport standards |
| EN818-2 Grade 80 Short Link Chain | EN818-2 is rated for overhead lifting and has a higher strength grade, but it is not certified for transport use and may not meet AS4344 requirements |
| Galvanized Chain | Yellow chromated zinc plated offers better corrosion resistance than standard galvanizing in transport environments with salt and moisture |
| Plastic or synthetic lashing straps | Chain provides higher strength and resistance to abrasion, UV, and cutting, making it more reliable for heavy or sharp-edged cargo |
Use Guide
How To Use And Inspect Grade 70 Transport Chain AS4344
- Use only within the stamped working load limit; do not exceed the safe working load
- Inspect chain before each use for weld defects, elongation, or surface damage
- Avoid side loading or twisting the chain during tightening
- Do not use for overhead lifting or suspended loads
- Keep chain clean and dry; reapply protective coating if surface damage is found
- Retire chain if the working load limit marking is illegible or if elongation exceeds 3% from original length
