Galvanized 3 Mm PPGL Steel Coil For Metal Roofing Zinc Aluzinc Coated

Manufacture PPGI PPGL Zinc Aluzinc Coated galvanized steel coil For Metal Roofing

Prepainted Galavalume Steel coils 

Shandong Fulilai Steel Group has delivered high-quality, long-lasting pre-painted galvalume steel sheet and steel coils with a high-grade finish that is uniform in color, gloss, texture and thickness. The strength of steel, the protection against corrosion and the beauty of color combine into a ideal product for you. Our prepainted steel products are available in a variety of material thicknesses, widths, and lengths as we offer multi-blanking and slitting services.

The surface of the galvanized steel sheet has a unique smooth, flat and gorgeous star flower, and the base color is silver white. The coating compositions consisted of 55% aluminum, 43.4% zinc, and 1.6% silicon, respectively, by weight. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, and it is a continuous molten coating process.
The galvanized steel sheet with 55% Al-Zn alloy coating has superior corrosion resistance compared with the galvanized steel sheet of the same thickness when both sides are exposed to the same environment. The galvanized steel sheet with 55% aluminum-zinc alloy coating not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.

heat reflective
The thermal reflectivity of galvanized steel sheet is very high, twice that of galvanized steel sheet, and people often use it as a thermal insulation material.

heat resistance
Aluminum-zinc alloy steel plate has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is very similar to high-temperature oxidation resistance of aluminized steel plate.

Corrosion resistance
The corrosion resistance of galvanized steel coil is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.

economy
Because the density of 55%AL-Zn is lower than that of Zn, the area of ​​the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet under the same weight and the same thickness of the gold-plated layer.

Easy to paint
The galvanized sheet has excellent adhesion to the paint and can be painted without pretreatment and weathering. Because the density of 55%AL-Zn is lower than that of Zn, the area of ​​the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet under the same weight and the same thickness of the gold-plated layer.
Galvanized steel has a silvery white ornate finish.
Galvalume steel and galvanized steel have similar processing properties and spraying properties
