RFQ Details

CGL dip the raw metal after surface pretreating, into liquid metal or alloy, which owns low melt point, during the process, the metal could get a protection layer, specially, the coated layer can form a metallurgy alloy with basic metal. The raw metal is always low carbon steel, alloy steel, cast iron, stainless steel. For coating melted metal, we always adopt zinc, aluminum, lead, tin or nonferrous, among these, zinc is most popular uses, for largely output, various specifies and widely uses. During whole processing, cold and hot rolled steel after processes 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, cold, 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 ideal corrosion resistance, easily moulding and coating, as well as its costly and good looking specialties, mainly apply for on construction, automobile, electrical appliances, now it is 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, furthermore, it enjoys more excellent electrical chemical protection, thicker and more density and good basic adhesiveness of coating layer, 600g/m2 zinc content of finished coating steel can ensure 30 years serviceable life, and no need to maintain it during using time. Addition to steel coil, for 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 high efficiency, competitive to other surface coating ways. Otherwise, for normal uses on compositional pieces, the cost of hot galvanizing method is far lower than other ways. So we appreciate to your best choices.
