DETAILS

Hot dip galvanized steel is also called hot dip galvanized steel or hot dip galvanized steel. The steel after the rust is immersed in molten zinc around 500 ℃ so that the zinc surface attached to the zinc layer, which played a preservative purpose, suitable for a variety of strong acids, alkali and other strong corrosive environment fog environment.
Hot dip galvanized steel process: I-steel pickling - washing - dipping plating solvent - drying preheating - hanging plating - cooling - passivation - cleaning - grinding - hot dip galvanizing completed. Galvanized steel galvanized layer thickness uniform, up to 30-50um, good reliability, galvanized steel and steel is a combination of metallurgy, a part of the steel surface, the hot dip galvanized steel beam coating Durability is more reliable.
Hot-dip galvanized steel I-beam for the raw materials, so the same classification in the I-beam. According to the process can be divided into hot-dip galvanized hot-rolled steel and hot-dip galvanized cold-rolled steel. Common hot-rolled hot-dip galvanized steel is the market. Hot-dip galvanized cold-rolled steel, generally need to customize with cold-rolled plate according to user needs.
product advantages
1, the processing cost is low: the cost of hot dip galvanized rust paint coating than other low cost;
2, durable: hot-dip galvanized steel with a surface gloss, uniform zinc, no leakage plating, no dripping, strong adhesion, corrosion resistance and strong features in the suburban environment, the standard thickness of hot-dip galvanized rust can be maintained Over 50 years without patching; standard hot-dip galvanized corrosion protection in urban or offshore areas for 20 years without repair;
3, good reliability: galvanized steel and steel is a combination of metallurgy, a part of the steel surface, the durability of the coating is more reliable;
4, strong coating toughness: galvanized layer to form a special metallurgical structure, this structure can withstand the transport and use of mechanical damage;
5, comprehensive protection: Each part of plating can be coated with zinc, even in the depression, sharp corners and hidden places can be fully protected;
6, save time and effort: galvanizing process than other coating method is faster, and can avoid painting the site after installation time required.
