Galvalumed Steel Coil Characteristics
1. Heat reflective:
GL Galvalumed Steel Coil made in China have a high heat reflectivity, which is twice that of galvanized steel sheets, which are often used as insulation materials.
2. Heat resistance:
The aluminum-zinc alloy steel plate has good heat resistance and can withstand temperatures of more than 300 degrees Celsius. It is similar to the high-temperature oxidation resistance of aluminized steel sheets, and is often used in chimney tubes, ovens, illuminators and fluorescent lamps. Corrosion resistance:
The corrosion resistance of galvanized steel coils is mainly due to the protective function of aluminum and aluminum. When the zinc is worn, the aluminum forms a layer of dense alumina that prevents the corrosion-resistant material from further corroding the interior.
Since the density of 55% of AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is larger than the area of the plated steel sheet by 3% or more in the case where the weight is the same as that of the gold-plated layer.
4. Easy to paint
Excellent adhesion between galvanized sheet and paint, lacquered without pretreatment and weathering.
The coating of the gold-plated zinc-plated steel plate has excellent adhesion. Therefore, without the pre-treatment of the zinc plate such as Weathering, the characteristics of the galvanized plate can be directly coated on the advertising plate and the general plate.
5. Aluminized zinc plated steel has a silvery white ornate surface.
6. Galvanized steel sheets have similar processing properties and spray properties to galvanized steel sheets.
