1. Product Characteristics


The vehicle steering system consists of handle and wheel. The handle axle and the wheel are connected together with a drive shaft. Should this connection break down, it will bring about a serious and fatal accident. Undoubtedly, the drive shaft is the most essential safety equipment in a vehicle.  We have made a substantial headway in advancing technology to make safe, low-weight, low-cost, highly fuel-efficient cars.  Hot-rolled steel sheet with excellent abrasion resistance and ductility is used to make uncompromising drive shaft pipes (this replaces existing bar type shafts).
