Galvanized silicon (GL) product is hot dip aluminizing (Al55%), zinc (Zn43.5%) and silicon (Si1.5%) alloy on surface of the strip steel with excellent corrosion resistance performance.
Hot-dipped gavalume alloy is successfully developed on the basis of hot-dip aluminizing and hot galvanizing. It does not only have the excellent resistance to the atmospheric corrosion, heat resistance and oxidation resistance, it also has the excellent electrochemical protection of the galvanized steel product, these make the incisions and scratches difficult to get corroded and rusted.;
Its main advantages are as follows:
(1) It has smooth surface with excellent resistance to atmospheric corrosion, its corrosion resistance life is 2-6 times longer than the hot-dipped galvanized steel sheet;
(2) It has good heat resistance and oxidation resistance, it can have long-term unchanging color at 300 ℃, it can be used over a long period of time at about 500 ℃, it has good resistance to water and soil corrosion, its water corrosion resistance is better that of the hot dipped galvanized steel sheet and hot-dip aluminized plate, the soil corrosion resistance is better than that of the hot-dipped galvanized steel sheet, and it is the ideal material for production of corrosion resistant components including automobile muffler, exhaust pipe, grain dryer, water heater and other corrosion resistant components; In addition, heat reflection factor of the product is higher than 75%, which is twice as that of galvanized sheet;
(3) It has excellent coating property and good processability. It also has strong binding force with organic materials, and it is the best choice for organic coated steel sheet. Its processability and weldability are similar with those of the hot galvanized plate, cold bending and stamping can be carried out. Furthermore, it also has good appearance.
