Product Description

Description for Hot Galvanizing Plate Hot galvanizing , is to dip the raw metal after surface pretreating. During the process, the metal could get a protection layer, consequently, the coated layer can form a metallurgy alloy with the raw metal.Usually, low carbon steel, alloy steel, cast iron, stainless steel is used as raw metal. For melted coating metal, we always adopt zinc, aluminum, lead, tin or nonferrous. Among these, zinc is most popular choice. General process goes as follows: uncoil, shear, welting, electro or alkali cleaning, entry storage loop, heating annealing and deoxidizing, hot dipping galvanizing, thickness controlling by air blade, spangle dealing, cooling, skin pass mill, leveller, passivation, exit storage loop, electrolytic oiling, shear and coiling, finally, the finished product is hot galvanized steel strip/coil. For this zinc coated steel plate possess features like its ideal corrosion resistance, easily moulding and coating, as well as good looking specialties, it is applied extensively in construction, automobile, electrical appliances, now it’s one of the fastest steel industrial within the whole steel improvement. Comparing to electrical potential of normal steel, chemical potential of hot galvanized steel is better. It enjoys more excellent electrical chemical protection, thicker and more density and good basic adhesiveness of coating layer. **0g/m2 zincon finished coating steel can ensure *0 years serviceable life, and no need to maintain it during using time. Additionally, thanks to its good applicability on steel shape, sizes, or dimension, this galvanizing technology also could be widely used in steel tube, wire or compositional pieces, with higher efficiency, thus more competitive than other surface coating ways. Otherwise, for normal uses on compositional pieces, the cost of hot galvanizing method is much lower than other ways.
