Versatile Security for Professional Haulers When you need a reliable tie-down solution that balances strength with ease of handling, 5/16″ Grade 70 chains are the top choice for many professional drivers. at Truck Trailer Pro, we supply premium transport chains designed to secure everything from farm equipment to light industrial machinery on flatbed trailers. These chains offer the robust holding power you need without the excessive weight of larger links.
Grade 70 (G70) chain is manufactured from heat-treated carbon steel, specifically engineered for load securement.
Superior Strength: With a Working Load Limit (WLL) of 4,700 lbs, our 5/16″ G70 chains are significantly stronger than standard Grade 43 chains, making them safe for highway transport.
DOT Identification: Recognized by their gold or yellow chromate finish, these chains are instantly identifiable by law enforcement as compliant for commercial tie-down applications.
Transport equipment takes a beating from the weather. That is why our 5/16″ chains come with a high-quality yellow zinc finish. This coating provides essential corrosion resistance against rain, snow, and road salt, preventing rust and ensuring that your chain links remain smooth and fully articulated for years of service.
Your cargo’s safety is our priority. All 5/16″ Grade 70 chains at Truck Trailer Pro meet or exceed NACM and FMCSA standards for cargo control.
Embossed Quality: Look for the grade markings stamped on the links, a guarantee of the chain’s quality and testing.
Proper Application: Always verify that the WLL of your chain assembly meets the requirements of your load before hitting the road.
