Hot-dip galvanizing is a process technology in which steel, stainless steel, cast iron and other metals are immersed in molten liquid metal or alloy to obtain a coating. Hot-dip galvanizing is a steel surface treatment method that is widely used in the world today and has an excellent performance-price ratio; hot-dip galvanizing products play an inestimable and irreplaceable role in reducing corrosion and prolonging life of steel, saving energy and saving materials. At the same time, coated steel is also supported by the state. And priority development of high value-added short-term products.
Good anti-corrosion performance, hot-dip galvanizing can effectively prevent steel from corroding in humid and corrosive environments, because zinc has good chemical stability and electrochemical stability, and can form a tight, firm and uniform zinc layer to protect Steel is not affected by corrosion;
Long service life, due to the good anti-corrosion performance of the hot-dip galvanized layer, the service life of the steel has been extended accordingly;
High surface flatness, the steel surface after hot-dip galvanizing treatment has a relatively high flatness, and there will be no defects such as rust spots and oxidation, which improves the aesthetics and use value of the steel;
Low maintenance cost, due to the good anti-corrosion performance of the hot-dip galvanized layer on the steel surface, the maintenance cost is relatively low, and frequent maintenance and maintenance are not required.
