Transport Chain G70

Electron transport chain is also referred to as a tie-down chain, or binder chain with increased hardening ability and improved resistance to wear which allows greater chain strength to weight ratio than Proof Coil Chain Grade 30 and High Test Chain Grade 43.

Stamped with “G70” on the link for easy identified and finished by zinc plated or yellow chromate. The yellow chromate finish offers better corrosion protection than other commercial link chains.

Grade 70 Transport Chain v.s. Grade 43 High Test Chain

  1. There are two main grades of chain for tie-down applications
  2. Grade 43 high test chain is used for stationary, non-transport tie downs.
  3. Grade 70 transport chain is for objects being transported on a flatbed or other moving vehicle.
  4. The G70 transport chain is a tractor tie-down chain for trailer ratchet cargo purposes, feature both high tensile strength and resistance to wear than ordinary low carbon steel grade 30 chain and high test chain G43.
  5. The transport chain is an ideal choice for load binding applications. It is also well suited for tie-downs, truck load binding application and for use in towing, construction, truckers chain towing, hi tie trailer tie system, container security, and safe working load(chain towing and logging chain). It is approved for truck tie-downs used for interstate transport.
  6. See our post “Which Grades of Chain Should I Choose?” for more about “chain grades“.
