Frequently Asked Questions
What is grade 70 transport chain used for?
It is the American standard chain for load securement - tying down cargo on trucks, trailers and flatbeds, and for towing.
Why is grade 70 chain yellow?
The yellow zinc chromate plating is the recognised colour code for grade 70, which makes the grade easy to identify on site. It also gives good corrosion protection for outdoor use.
What sizes and working load limits are available?
From 7 mm to 16 mm diameter, with working load limits from about 1,430 kg to 7,170 kg. Tell us what you are securing and we will confirm the size and fittings.
Is grade 70 chain suitable for overhead lifting?
No. It is a transport and load securement chain, not an overhead lifting chain. Use a grade 80 or grade 100 lifting chain for overhead lifting.
Do you also supply other American standard grades?
Yes - grade 30 proof coil and grade 43 high test are available alongside grade 70. Tell us the application and we will recommend the grade.
