1. Tri axle trailer frame
High strength of high-strength steel: The biggest feature of high-strength steel is its high strength. The yield strength of high-strength steel is twice that of manganese steel and three times that of ordinary steel.
When flatbed trailer manufacturers frame, it bears the same strength. The frame made of high-strength steel uses less material. The upper wing plate, lower wing plate and vertical plate can be made thinner and lighter. Under the premise of charging by weight and standard loading, the advantages are more obvious.
