1. Prepainted Galvalnized corrugated sheet introduction:
Prepainted Galvanized corrugated sheet is one of the most corrosion resistant corrugated materials offered
in the architectural roofing and siding panel market. Galvalnized corrugated sheet will give you a great product
that lasts longer than the traditional galvanized finish. The corrosion resistance of this galvanized corrugated
sheet will make this the ideal product for almost any application, by marrying the lightweight aspect and
advantage of zinc coating, with less chance of the material corroding at the normal stress points, and areas
where rusting can start.
2. Prepainted Galvalnized corrugated sheet main structure:
Prepainted Galvanized corrugated sheet is carbon steel sheet coated with zinc coating by a continuous
hot-dip process described in Production Methods. Besides, the raw material could also be galvalume steel
and prepaited steel (GI,GL,PPGI,PPGL).
3. Prepainted Galvanized corrugated sheet application scope:
Prepainted Galvanized corrugated sheet is widely used for commercial, agricultural, and industrial purposes,
however, it is now also being recognized as an excellent form of residential roofing. Galvanized steel sheet
is also known as sinusoidal, corrugated iron or wriggly tin.
4. Prepainted Galvanized corrugated sheet main features:
1)Combine the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc.
2)Preferred product for long-term resistance to atmospheric corrosion
3)The superior corrosion resistance of galvanized steel sheet is achieved by the presence of microscopic
zinc-rich and aluminum-rich areas within the coating.
4)Easy to install, high strength and lower costs
5)Painted Galvanized corrugated sheet is widely used as walls or roofs for factories, warehouses, garages, exhibition centers
5. Prepainted Galvanized corrugated sheet installation tips:
1)Prepare the roof surface by removing any old roofing, rotten wood, and adding roofing felt to the entire surface.
2)Calculate the number of sheets of corrugated metal needed. Divide the area of your roof by the size
of the sheets you will be using. Remember that you will want the metal sheets to overlap.
3)Place your first metal sheet in a corner of the roof, flush against the surface.
4)Nail in the first metal sheet to the wood of the roof. You should use about 20 nails per sheet.
Whenever possible, nail in the valley between the ridges, where the roofing is closest to the wood.
