Grade 70 Transport Chain With Grab Hooks
Product Description
Grade 70 Transport Chain With Grab Hooks
Thinkwell Grade70 Transport Chain Assembly fitted with clevis/eye grab hooks on both ends, manufactured from high-strength alloy steel 20Mn2, fully quenched & tempered heat-treated. Yellow zinc-plated golden finish for quick visual inspection, complying with ASTM80, NACM90, NACM96 standards and ISO9001:2015 quality system. Widely used for flatbed cargo tie-down, truck towing, logging, trailer safety securing and oil rigging. Not suitable for overhead lifting. G70 chain delivers approx 20% higher working load than Grade43 high-test chain, it is the most popular trucker transport chain across North-American cargo transportation industry.

Grade 70 Transport Chain Key Features & Advantages
✅ High-Strength Alloy Steel & Full Heat-Treatment
Raw material 20Mn2 alloy steel, quenched & tempered heat-treatment process to achieve excellent tensile performance. Minimum Breaking Load(M.B.L) equals 4 times Working Load Limit(W.L.L), safety factor 4:1 for heavy-duty load securement.
✅ Yellow Zinc-Plated Anti-Corrosion Finish
Distinctive golden-yellow zinc plating surface treatment, easy identification during highway cargo inspection; alternative hot-dip galvanizing available upon request, good rust-resistance for outdoor harsh working conditions.
✅ Dual-End Grab Hook Assembly
Complete chain assembly pre-fitted with clevis grab hooks on both terminals. Drop-forged grab hooks match chain grade perfectly, secure quick connection for load binders, trailers and towing jobs. Multiple inch sizes & lengths in stock.
✅ Strict Batch-by-Batch Quality Testing
Every production batch conducts mandatory tensile proof-load test, all chain links stamped with G70 grade marking for traceability. ISO-certified factory, 12-month product warranty.
