Punching net anti-skid plate after galvanizing can increase the anti-skid plate corrosion resistance, can effectively improve the punching net anti-skid plate life. Galvanized punching net anti-skidboard is divided into cold galvanized and hot galvanized two, in recent years, with China's awareness of environmental protection more and more aware of our policy has been introduced cold galvanized has been listed , And hot-dip galvanizing technology is the country to promote the use of. To tell you what is hot galvanized, what is cold galvanized.

Hot-dip galvanizing technology is the use of molten metal and iron matrix produced by the reaction of the alloy layer, so that the iron matrix and zinc coating combined with a technology. Hot-dip galvanizing is to now the steel plate for pickling procedures, which is to remove the surface of the steel plate of iron oxide, so that later the fusion can not be destroyed by iron oxide. After pickling, the steel plate is impregnated with ammonium chloride, an aqueous solution of zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride for cleaning, and then heated into a hot-dip zinc bath so that zinc can be plated. Hot galvanized with a uniform coating smooth, strong adhesion and long service life advantages.
