The Industry Standard for Flatbed Trucking If there is one piece of equipment every flatbed hauler needs, it is the G-70 3/8 Chains. At Truck Trailer Pro, we supply the high-performance chains that keep America’s freight moving. Striking the perfect balance between manageable weight and immense tensile strength, our 3/8″ chains are the go-to solution for securing heavy loads, from steel coils to agricultural machinery.
Why G-70 3/8 Chains is the Pro’s Choice
Grade 70 (G70) chain, manufactured from heat-treated carbon steel, is roughly 20% stronger than High Test Grade 43 chain.
Optimal Strength: With a Working Load Limit (WLL) of 6,600 lbs, a 3/8″ G70 chain provides the holding power needed for interstate transport without being overly heavy to handle during rigging.
Easy Identification: Per DOT regulations, our chains feature the signature gold or yellow chromate finish, making them instantly recognizable to inspectors as safe for highway transport.
Built for the Long Haul
Your equipment faces rain, snow, road chemicals, and constant vibration. Our 3/8″ transport chains are finished with a durable yellow zinc coating that resists corrosion and rust better than standard painted chains. This protective layer ensures your chain links remain flexible and free of structural damage, season after season.
Safety and DOT Compliance
Hauling heavy cargo comes with serious responsibility. All our 3/8″ Grade 70 chains are rigorously tested to meet or exceed NACM and FMCSA specifications.
Embossed Links: Every few links, you will find a grade stamp indicating the chain’s quality, a requirement for DOT inspections.
Reliable Performance: Whether you are using lever binders or ratchet binders, our chains are designed to hold tension securely, preventing load shifts.
