High Quality Performance of Galvalume Sheets
The galvalume steel sheet is composed of aluminum-zinc alloy, which is formed by solidification of 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C. The whole structure is made of aluminum-iron-silicon-zinc, forming a dense four. Elemental crystal alloy. Aluminized galvanized steel sheet is a new type of steel sheet which is processed by hot dip coating of cold rolled or hot rolled steel sheet. Its corrosion resistance is gradually replacing galvanized sheet widely used all over the world.
Aluminized galvanized steel sheets usually have the following characteristics:
1. Superior corrosion resistance: The corrosion resistance of galvanized steel sheets is 6-8 times that of ordinary galvanized sheets, and it is usually guaranteed to rust for 20 years.
2. High temperature oxidation resistance: The galvanized steel sheet will not be discolored or deformed if it is used continuously in a high temperature environment of 315 °C.
3. High heat reflectivity: The heat reflectance of galvanized steel sheet is higher than 75%, which is about twice that of galvanized sheet. When it is not painted, it can be used as roof and panel to achieve energy saving effect. Processing is easy: Stamping, shearing, bending and other processing.
