Bead Wire
Bead Wire, is a kind of steel wire plated with bronze, copper or brass as reinforcement of bead on Tyres. The Bead ring woven by the bead wire and the insulating rubber makes the outer tire tightly and firmly fixed on the tire rim, and bears the forces of tension, compression, torsion and centrifugal force during car driving.
As one of bead wire suppliers, Yusheng’s bead wire material has high tensile strength, high toughness, good fatigue resistance, remarkable adhesion to rubber.
