US NACM standard G70 Transport Chain

G70 Transport Chain Quick Overview

Thinkwell US NACM & ASTM compliant G70 Transport Chain (also called trucker’s chain) is heavy-duty alloy steel tie-down chain with gold-color zinc-plated finish. Through strict heat-treatment process, G70 chain delivers about 20 % higher strength than Grade 43 High-Test chain, becoming the most widely-used securing chain for flatbed trailers and cargo transportation in North America. Each batch goes through tensile testing. ISO-certified factory with 12-month warranty.

G70 Transport Chain Product Introduction

Our G70 transport chain is constructed from premium alloy steel and processed with precise quenching & tempering heat-treatment, maximizing tensile strength and impact resistance for heavy-load stabilization.

Compared with Grade 43 high-test chain, G70 provides superior strength-to-weight performance. Each chain link is embossed with grade marking for easy identification and traceability. The yellow zinc-plated surface improves anti-corrosion performance in outdoor and transportation environments.

Commonly named “trucker chain”, this welded link chain is the mainstream securement solution for North-American road transport. Besides raw chain lengths, also supplies finished chain assemblies fitted with grab hooks, clevis pear links, triangle rings for ready-to-use tie-down sets.
