High test chain (grade 43) is an alloy steel chain to the NACM 90 standard. It is stronger than proof coil chain of the same size and is a common choice for transport and general duty work.
Where G43 High Test Chain Is Used
Used for transport, towing, logging and general purpose applications where a higher strength-to-weight ratio than proof coil chain is needed. It is not a grade-marked overhead lifting chain.
Material and Surface Finish
Alloy steel, self color or polished. Grade 43 is the American standard high test grade; grade 30 proof coil and grade 70 transport chain are also available.
Sizes and Ordering
Standard sizes run from about 6.5 mm to 16 mm diameter, with working load limits from about 1,180 kg to 5,220 kg. Tell us the working load of your application and we will confirm the size.

Frequently Asked Questions
What is grade 43 high test chain?
It is an alloy steel chain to the American NACM 90 standard, stronger than grade 30 proof coil chain of the same size. It is a common choice for transport and general duty work.
How does grade 43 differ from grade 30 and grade 70?
All three are American general duty grades: grade 30 (proof coil) is the commercial grade, grade 43 (high test) is made from alloy steel for more strength, and grade 70 (transport) is the load securement grade. None of the three is a grade-marked overhead lifting chain.
What sizes and working load limits do you supply?
About 6.5 mm to 16 mm diameter, with working load limits from about 1,180 kg to 5,220 kg. Choose the smallest size that covers your load with a margin - a larger chain is heavier and more expensive than you need. Tell us the working load and we will confirm the size.
What is 'self color' finish?
It is the natural, uncoated finish - no plating or painting. Choose it where you want the chain as manufactured; polishing is available if a brighter appearance is wanted.
Is grade 43 chain suitable for overhead lifting?
No. It is a general duty and transport chain, not an overhead lifting chain. For overhead lifting use a grade 80 or grade 100 lifting chain matched to the load.
