The gold chromate finish makes it easy for DOT officials to recognize.

Typically used by truckers, loggers, and highway crews for load securement and towing..

Can bolt cutters cut grade 70 chain?

Grade 70 transport chain is a high strength alloy and is very close in toughness, but much cheaper. … The 3/8″ chain size should be impossible to cut with all bolt cutters of common sizes no matter what the conditions.

What chain is hardest to cut?

Pewag chainBy being the toughest chain, we mean the Pewag chain is the hardest chain to cut with bolt cutters. The biggest reason is the hardened steel chain is squared, so it will not allow bolt cutters to cut through it.

What is a 43 grade?

Does grade 70 chain rust?

Grade 70 chains, also known as transport chain or trucker’s chain, are designed as load securement. … G70 chains are made from a higher strength, heat-treated carbon steel and have a load rating approximately 20 percent higher than Grade 43. The gold chromate coating offers them more resistance to rust and corrosion.

What is proof chain?

Proof coil is a general purpose, carbon steel chain. Common uses are for binding or tie down chains, tow chains and logging. This chain comes in galvanized or self-colored and can either be sold by the drum or by the foot. It is not to be used for overhead lifting.

How strong is grade 43 chain?

Grade 43 has a working load limit ranging between 2,600 to 13,000 lbs. Grade 43 is also commonly labeled as High-Test Chain or G-4 chain and is comprised of carbon steel, which is known for its high tensile strength and wear resistance.

Is chain or cable stronger?

Chain is more rugged than a cable..so in rough use a chain is a better choice but for safety sake and pure strength a cable is stronger.

How many chains does it take to secure a load?

The load being tied down must not exceed the combined WLL of all the chains being used. For example, if your cargo weighs 8,000 lbs and you will use 4 chains, each chain must have a WLL of at least 2,000 lbs. Four chains of 2,000 lbs WLL each will equal 8,000 lbs total, enough capacity to secure an 8,000 lb load.

Is cable harder to cut than chain?
