Galvalume Aluzinc Steel Coil Manufacturers

Qingdao Sino Witop Steel Co.,LTD are a leading manufacturer and supplier of Galvalume Aluzinc Steel Coil in China. Witop Steel have two galvalume steel production lines with annual capacity of 200000 tons, which can produce JIS G 3321, EN 10215 and ASTM 792 standard. Galvalume Aluzinc Steel Coil have been exported to more than 100 countries and regions including Africa, the European Union, South America, Middle East, Southeast Asia, and Central Asia. Galvalume Aluzinc Steel Coil have gained wide acceptability throughout South America due to its versatility and performance.

Hot-dip aluminum-zinc-silicon steel coil, Galvalume (GL for short), is a steel sheet made of hot-dip aluminum(Al55%), zinc (Zn43.5%), and silicon (Si1.5%) alloy on both sides. Galvalume Aluzinc Steel Coil have proven its superior performance as a corrosion resistant building material in a diverse range of environments. Galvalume Aluzinc Steel Coil also have heat resistance and oxidation resistance, excellent and superior processing performance.

Galvalume Aluzinc Steel Coil has more advantages than galvanized steel coil.
1. Heat reflectivity:
The heat reflectivity of Galvalume Aluzinc Steel Coil is very high, which is twice that of galvanized steel coil. So people often use it as the material for heat insulation.
2. Heat resistance:
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is often applied in chimney tubes, ovens, luminaires and fluorescent lampshades.
3. Corrosion resistance:
The corrosion resistance of of Galvalume Aluzinc Steel Coil is due to the protective function of aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.
4. Economical and practical:
The density of 55% AL-Zn is lower than that of Zn by weight, the area of the of Galvalume Aluzinc Steel Coil is more than 3% larger than that of the galvanized steel sheet with the same weight and the same coating.
5. Easy to paint
The aluminum-zinc steel coil has excellent adhesion to the paint and the paint can be coated without treatment.
6. Galvalume Aluzinc Steel Coil has a gorgeous silver-white surface.
