Hot dip galvanizing is heated in the melting zinc liquid dip coating, production speed, coating thickness but not uniform, to allow the market to a minimum thickness of 45 microns, up to a maximum of 300 microns above. The darker color, consumption of zinc metal, and the metal substrate is formed into layers, good corrosion resistance, the outdoor environment can be maintained for decades of hot dip galvanizing

because the coating thicker than galvanized, hot galvanized have better protection performance, so it is to be used in harsh working environment protection coating on steel parts. Hot galvanized products in chemical equipment, oil processing, marine exploration, metal structure, electricity, shipbuilding and other industries are widely used in agricultural fields, such as pesticide spray irrigation, greenhouse as well as the construction industry such as water and gas transportation, wire casing, scaffolding, bridge, highway guard rails and other aspects, in recent years has a lot to be used.
