Hot dipped galvalume steel coil, Aluminum-zinc alloy

Product Description

Galvalume (GL) Galvalume

   Galvalume Steel Sheet_Aluminum-Zinc Alloy Coated Steel Sheets (GL) are galvanized steel sheets with both zinc and aluminum, and is the ideal combination of anti-corrosion and alkali-resistance of zinc, and the durability, heat-resistance, and acid-resistance of aluminum. The galvanized layer is consisted of *5% of aluminum and *3.3% of zinc and 1.6% of silicon per weight, and *0% aluminum in terms of volume ratio, so while the advantages of aluminum is well preserved zinc prevents the risk of red rust on the surface, a weakness of aluminum, and the product combines the strengths of both materials.

Characteristics

• GLs are 3~6 times more corrosion-resistant compared to GI, but has a similar level of processability and weldability and can replace GIs, and in particular is most suitable when replacing GIs that require thick galvanized layers and high corrosion resistance.
• Only galvanized steel sheet that is used for roofing and walls without painting because of its unique silver spangles and beautiful appearance and high-corrosion resistance, and is used as a cool roofing material because of its excellent heat reflection qualities.
• Can replace aluminum gilded steel sheets because for certain purposes of its ele trical conductivity and its heat-resistance qualities even at high temperatures that do not exceed **5℃.
• Has greater surface hardness than GIs, and is much more wear-resistant.
• Corrosion resistance increased more with resin-coating treatment, which enables roll forming or press forming without the spraying of processed oils.

Purpose

Building exterior roofing and walls, heating panels, boilers, pipes, premium fences, distribution panels, refrigerator back plate, DISPLAY, home appliance parts, and etc.
