high quality galvalumed steel sheet is a kind of corrosion resistant steel grid product which can dip the welded steel grid plate into the molten zinc or zinc alloy and form a zinc coating on the steel surface. Hot dip galvanizing is now the most widely used, cost-effective steel corrosion treatment. Hot dip galvanizing technology can prevent the corrosion of steel products, prolong the service life, saving energy consumption has an irreplaceable role, hot dip galvanized steel is also the development direction of energy-saving society.
The corrosion resistance of high quality galvalumed steel sheet is due to the fact that the standard electrode position of zinc is negative to the standard electrode potential of iron. Therefore, in the presence of water or humid air, the anode zinc layer is sacrificed to protect the steel base and maximize the service life of steel products. Hot dip galvanizing, electric galvanizing, hot spray galvanizing, mechanical galvanizing are commonly used in modern industry, and hot dip galvanizing accounts for about 80 percent of all above.
In recent years, economic development, a large number of projects continue to start, environmental engineering, coal to natural gas, desulfurization and denitrification, Marine engineering, shipbuilding, steel industry transformation, has created a large number of galvalumed steel sheet applications, but also to aluminum and zinc production enterprises have brought a good opportunity for development, should seize the opportunity to quickly strong.
