G70 Chain
Product Description:
G70 chain is made of heat treated carbon steel without any alloying elements added. With a gold(zinc yellow) chromate finish, G70 chain owns better capability resisting corrosion from continuous exposure such as to the rigors of highway use. Its load ratings are approximately 20% higher compared with G43 chain, according to ASTM & NACM specifications. G70 chain is not intended for overhead lifting.
Features of G70 Transport Chain:
• Material: heat treated carbon steel;
• Standard: ASTM & NACM;
• Finish: chromated,black painted, galvanized;
•Packing: drums, pails or customized;
•Purpose: safe tie downs in trailer, logging and oil rigging;
• Not for overhead lifting.
