Galvanized steel coil is cold-rolled steel sheet as raw material, after cleaning, annealing, hot galvanizing, polishing, tension leveling, passivation process, the final coiled coil of steel. 聽 What are the uses of galvanized steel coil? Galvanized steel coil is widely used because of its good anti-corrosion function. Galvanized steel coil is mainly used in the construction industry, such as: manufacturing as if industrial or civil building roofing panels, roof grids, etc. Galvanized steel coil are also used in light industry, such as the manufacture of home appliance casings, civil chimneys, kitchen utensils, etc. Galvanized steel coil can also be used in the automobile industry, such as the manufacture of corrosion resistant parts for cars. Galvanized steel coil is also often used to do grain storage and transportation, meat and aquatic products frozen processing equipment. In addition, galvanized steel coil is often used in materials storage and packaging appliances. 聽 What's the difference between hot galvanizing and cold galvanizing? Hot dip galvanizing is to melt the zinc ingots, dip the metal parts into the galvanized groove, make the metal parts attached with a layer of zinc layer, the adhesion and hardness of the galvanized layer is better, so as to play the purpose of anti-corrosion, so the corrosion resistance of hot dip galvanizing is stronger. Cold galvanizing is electric galvanizing, with less zinc, which is attached to the surface of the metal parts with a layer of metal film, which can play the role of anti-corrosion and wear resistance. Hot dip galvanizing is a chemical reaction. Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and the coating of the two combination. The surface of hot galvanizing and cold galvanizing is different. The zinc layer of hot galvanizing is thick and the surface is rough. The zinc layer of cold galvanized is thin, but the zinc layer is delicate and bright, and the zinc layer is uniform. The price of hot galvanizing is relatively high, and the price of cold galvanizing is relatively low. 聽China Steel Coil factory website:http://www.lumeisteel.com/steel-coil/
