Product Description
PPGI:
1, Introduction: Color coated steel coils(sheets), i. E. PPGI, also called prepainted steel coils(sheets), are made of galvanized steel coils(sheets) with polymer coatings as surface. It's a new enclosure material and building board with characteristics of light-weighted, heat preserved&insulated, easily installed with bright colors.

2, Production Process: Pretreatment(Degreasing)_Drying_Chromating_Paint Basic Oil_Cooling_Drying_Color Coating_Cooling_Film-covering_Rolling Up

3, Characteristics:
Good at corrosion resistence. Besides zinc coating of the basic plate of galvanized steel sheet, the color coating as the surface has double lifetime to ensure better anticorrosion effect.

With excellent cold bending molded manufacturablity, PPGI products can be processed or directly used as final product. As being light-weighted and conveniently transported, they're widly used to replace wood to save energy.

There're thousands of colors can be chosen as per different application. Any color plays well in decoration.

No pollution with high recycling rate, PPGI coils and sheets are strongly recommended as enviroment-friendly products by the government.

4, Appliance: Thanks to the above characteristics, color coated steel coils and sheets are widly used in construction, furniture industry, transportation industry, ect.

5, eye bands and 4 circumferential bands in steel, galvanized metal fluted rings on inner and outer edges, galvanized.

CUSTOMER: What price is this product?
Us: It is according to the size, quantity and surface treatment. The thickness of the thinner, the more expensive, the zinc layer is thick, more expensive.
CUSTOMER: How many grams of largest zinc layer?
Us: The zinc coating is 30-275g/m2. The cheapest is 30g/m2.
CUSTOMER: Can you produce it with spangles?
Us: Yes. We can produce big spangles, regular spangles and small spangles.
CUSTOMER: What is the difference price between spangles?
Us: The big spangles price is expensive 10USD/Ton than small spangles. If the quantity is big, we can give you the same price.
CUSTOMER: Can you produce galvalume steel?
Us: Yes, we can. By 55% aluminum, 43% zinc and 2% silicon at 600 º C high temperature solidification and composition.
