perforated metal sheet for ceiling

Hot dip galvanizing of steel plate is also called hot dip galvanizing. Zinc ingots are melted in the tropics and some auxiliary materials are added in hot dip galvanizing. The steel grid parts are then soaked in a galvanizing tank and a galvanizing layer is attached to the steel plate. The strength of hot dip galvanizing depends on its corrosion resistance, and the adhesion and hardness of galvanized sheet are better. The amount of galvanized steel plate after galvanizing. So this is the general amount of zinc.

Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

The color of powder coating is divided into: razor wire blue, grass green, dark green, yellow. Plastic-sprayed blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out of sharp knife sheet, high tension galvanized steel wire or stainless steel wire as core wire combination of resistance devices. Because the shape of the barbed rope is not easy to contact, so it can reach an excellent protective barrier effect. The primary raw materials of products are galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, plastic coated, plastic spraying) wire, blue, green, yellow and other colors.

Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with electrogalvanizing, hot galvanizing has lower production cost and less impact on the environment than electroplating.
