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

4. Details for Main applications
The prepainted steel sheet for construction is an attractive substitute for wood and other materials owing to its advantages, including excellent and fast color, good durability performance, chalking resistence, good corrosion resistence, etc, it is an efficient construction material, with energy saving, preventing pollution and good economic effect. At the same time, various colors , surface structures and coatings provide products with great flexibility and option.
2) Electrial Appliance
The prepainted steel sheet for household appliances often takes electro-galvanized, hot-dip zinc-coated and color rolled steel sheet as its base metal, which is widely applied in manufacturing refrigerators, large-scale air-conditioning systems, refrigerating cabinet, bread maker, furniture,etc.
5. Advantages of HANKE PPGI:
1) Such as: fast color, good durability performance,chalking resistance, etc.
2) Minimized the maintenance cost.
3) Various colors, surface structures and coatings provide such products with great flexibility and option.
In China, more than 90% color coated sheets are applied in construction.
