1.Hot Dipped Galvanized Steel Coil is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective method of metal anti-corrosion, mainly used in metal structural facilities in various industries. It is a process technology for immersing steel, stainless steel, cast iron, and other metals into molten liquid metal or alloy to obtain a coating. It is the most widely used and cost-effective steel surface treatment method in the world today. Hot-dip galvanized products play an immeasurable and irreplaceable role in reducing corrosion and prolonging life, energy saving, and material saving of steel. At the same time, coated steel is also a high-value-added short-term product supported and prioritized by the state.
2. Development History
Hot-dip galvanizing was invented in the middle of the 18th century. It was developed from the hot-dip tinning process and has entered the fourth century. So far, hot-dip galvanizing is still the most common and effective technological measure in steel corrosion protection.
