Tyre bead wire

tyre bead wire high carbon steel wire brass coated steel wire copper coating wire Our company in the production process, the selection of domestic Baosteel, Shagang, and several well-known high-quality steel wire, the application of advanced environmentally-friendly thermal diffusion of copper plating production lines, the use of sophisticated TB4 Straight and drawing equipment, plated brass GB/T11182-2006 wire strictly enforce standards, the specifications of its production is (0.12-1.2), with which the 0.12-0.4mm package for the Public Works Sub-round (iron axis) packaging, the actual standard weight of 25kg / axis, 0.5 -1.2mm for the flexible packaging (plate silk) packaging, weight of 50kg / wire bundles. Strict implementation of the two products GB C Group tensile strength.

Bead wire is an essential reinforced material for tires on automobiles and aircraft. This product prevents tires from changing shape due to air pressure or external forces , and it safely locks the tire onto the rim to prevent vibration while driving .
