On the basis of the two steel corrosion control method of hot dip galvanized steel sheet and hot-dipped galvalume steel sheet, galvalume steel sheet is developed based on their advantages. The cladding material of hot-dipped galvalume steel sheet has a series of advantages that the zinc coating does not have. And its use is more and more widely.
According to CAMELSTEEL know, the occasions that galvanized steel sheet can be used, galvalume steel sheet also can be used. And in most of the occasions, the aluminum plate can also be replaced by galvalume steel sheet.
1. Replace galvanized steel sheet to use in the occasions that has high corrosion resistance. The resistance to atmospheric corrosion and resistance to wet gas corrosion of galvalume steel sheet is better than galvanized steel. And it can be used for a variety of materials and components of internal and external building.
2. Replace galvanized steel sheet to use in the occasions that has high processability. Its processing performance is same with galvanized steel sheet, they all have good bending formability, excellent unidirectional ductility and weldability. It also can cold-formed, stamping and welding into parts with various shapes.
3. Replace aluminum steel sheet to use in the occasions that has high heat resistance and inoxidizability. Galvanized steel can be used for the high-temperature environment which can only use aluminum steel sheet but not galvanized steel. Such as the oven, dryer and cooler of household appliances, tail pipe, muffler, heat shield and so on.
4. Replace galvanized steel sheet and aluminum steel sheet to use as the substrate of color coated steel sheet and patterned sheet. Galvalume steel sheet has small crystal, and the same with aluminum steel sheet and galvanized steel sheet with small spangle or zero spangle, it has strong adhesion to coating. It also can be used as a color coated substrate and printed substrate.
5. It has a lower cost of production than galvanized steel sheet and aluminum steel sheet, and has good economical efficiency. Galvalume steel sheet not only saves a lot of high price aluminum, and compared with the galvanized steel sheet with the same weight, thickness and width, the unrolling length of the coil is about 5% longer. That bring s the lower production costs and higher prices, also can increased economic efficiency of enterprises.
