The surface of galvanized steel wire is smooth, smooth, without cracks, joints, prickles, scars and corrosion. The galvanized layer is uniform, strong adhesion, durable corrosion resistance, excellent toughness and elasticity. Tensile strength should be between 900 Mpa and 2200 Mpa (wire diameter 0.2 mm-4.4 mm). Torsion times (0.5 mm) are more than 20 times, and repeated bending should be more than 13 times. The thickness of galvanized layer is 250g/m. The corrosion resistance of steel wire is greatly improved.
