Grade 70 is extremely strong for its light weight and is used primarily for load binding in the transportation industry. However, it is also used extensively on farms, in lumbering, towing and construction. Grade 70's high strength to weight ratio is achieved by special heat treating. It resists wear because of its exceptional hardness properties.
MATERIAL - Carbon steel.
FINISH - Matte Grey Finish or Yellow Dichromate.
ATTACHMENTS - Can be supplied in assemblies with forged clevis grab hooks on each end and other attachments as required.
Grade 70 is approved by the Department of Transportation for truck tiedown use. Dominion Chain Grade 70 meets all applicable Provincial requirements.
TEST CERTIFICATE - All Grade 70 chain is proof tested. Proof test certificates are furnished on request.
