Galvanized steel wire surface smooth, bright and clean, there is no crack, the joint, from the thorn injuries and rust, zinc coating uniformity, strong adhesion, corrosion resistane and lasting strength, excellent toughness and elasticity. tensile strength should be between 900Mpa-2200Mpa (wire diameter 0.2mm-4.4mm). To reverse the number (0.5mm) im more than 20 times, repeatedly bending in more than 13 tmes.
