The hot-dipped galvanized steel is the most widely used and cost-effective steel in the world. It plays an irreplaceable role in terms of steel corrosion reduction and life extension, which makes it an energy-saving material. Also, it is a high value-added short-term product supported by many countries.
Hot-dipped galvanization is an effective way to prevent the base metal (CRC) from corrosion, and it is mainly used for producing steel structures and industrial facilities. The galvanized steel is produced by immersing the base metal into a molten zinc pot at 450 – 500℃ after removing grease or dust on its surface to adhere the zinc layer to both sides of the sheet surface, and thereby preventing corrosion.
