Galvalume Steel Coil
1. High temperature resistance: good performance at temperatures above 300℃.
2. Corrosion Protection: Aluminum layer protects the steel interior.
3. Easy to Paint: Aluminized steel plate with perfect adhesion to give your finish a great look.
Product Introduction
Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600℃. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.
