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 .
