Tire Cord Steel
Tire cord steel is mainly used for the production of tire cord used as the framework materials of meridian tire for car, truck and planes, with very high tensile strength, outstanding heat resistance and impact resistance performance. As framework materials, it is widely used in rubber products including tires, rubber hose, transportation, etc. The product size is Φ 5.5 ~ 6.5 mm of hot-rolled wire rod, and it is mainly used for production of tie cord wire for meridian tire, outer woven wire and wire winding, hose, bead wire, etc.
