Maximum Security for Heavy Hauling When your cargo weighs tons, you need hardware that inspires confidence. Truck Trailer Pro offers premium 1/2″ Grade 70 chains designed for the heaviest transport applications. Often referred to as “transport chain” or “log chain,” these heavy-duty links are the preferred choice for securing large construction equipment, industrial machinery, and logging loads on flatbed trailers.
Why Choose 1/2″ Grade 70 Chain?
Grade 70 (G70) chain is heat-treated carbon steel engineered for superior tensile strength.
Higher Working Load Limit: Our 1/2″ G70 chains offer a significantly higher Working Load Limit (WLL) compared to standard Grade 43 chains, making them essential for heavy-duty commercial towing.
DOT Recognition: Easily identifiable by its gold or yellow chromate finish, this chain is universally recognized by DOT inspectors as the correct grade for highway transport.
Engineered for Extreme Durability
Heavy hauling exposes your equipment to the harshest elements. Our 1/2″ chains feature a tough yellow zinc finish that provides excellent protection against corrosion, road salt, and abrasion. This ensures that the chain maintains its integrity and flexibility even after prolonged exposure to rain, snow, and mud.
Safety and Compliance
There is no room for error when securing heavy machinery. All our 1/2″ transport chains are manufactured to meet or exceed NACM and FMCSA specifications.
Embossed Markings: Each link is stamped with grade markings to verify authenticity and strength.
Load Securement: Always ensure your chain’s WLL matches the requirements of your load to stay compliant and safe on the road.
