Galvalume Steel Roofing Sheet
●The galvalume steel roofing sheet is made of galvalume Steel coil and processed by a roll forming machine.
●The anti-fingerprint galvalume steel roofing sheet is coated with anti-fingerprint liquid on the galvalume sheet and plays a role in anti-rust. It is mainly exported to Southeast Asia.
1) The corrosion resistance of galvalume steel roofing sheets is 3 to 5 times that of corrugated galvanized steel sheets, and the more severe the corrosion, the greater the difference. Therefore, in the construction roof, corrugated galvalume steel sheets AZ150 should be preferred.
2) AZ150 is about 10-20% more expensive than Z275, but its corrosion resistance is 3~5 times.so corrugated galvalume steel sheets has excellent performance and cost performance.
Corrugated Galvanized Steel Roofing
●The corrugated galvanized steel roofing is made of galvanized steel coil and processed by a roll forming machine.
●According to the difference of galvanizing, it is divided into big spangle and zero spangles. According to the production method, it can be divided into hot-dip galvanized steel, electro-galvanized steel, and alloy-galvanized steel.
●African customers mainly purchase 0.13*665 length, with zero spangles corrugated galvanized steel roofing.
●Among them, we mainly sell corrugated hot-dip galvanized steel sheets because the production of electro-galvanized steel sheets will pollute the environment.
●The logo can be customized on the surface of the corrugated galvanized steel sheet according to customer requirements.
The corrugated galvanized steel roofing has a double-sided coating weight of 20-700 g/m2 according to ASTM test. The most commonly used corrugated galvanized steel sheets for building applications are Z275 and Z450, and the galvanizing amount is 275 g/m2 (the minimum thickness of the single-sided coated of the steel sheet is 19 μm) and 450g/m2.
