1. Descprition about base metal
Galvalume is the result of an ideal alloy of aluminum and zinc. It consists of aluminum(55%), zinc(43.4%), and silicone(1.6%).
Characteristics of Galvalume:
1) Corrosion resistence:
At verious enviromental conditions, GL shows better corrosion resistence than GI if the thickness is same, its service life is 2 to 6 times than ordinary galvanized steel. The corrosion resistence in the machining parts is much better than that of hot-dip galvanized due to micro cracks demormation parts of aluminum zinc plate is smaller than hot-dip galvanized.
2) Heat resistence:
GL plate can be used for a long time even if under 315℃.
3) Heat reflective
The reflection coefficient is double than that of hot-dip galvanized steel, which can reduce the inner tempeture in summer
