1. Prepainted Galvalnized Steel Roof Sheet introduction:
It is one of the most corrosion resistant materials offered in the architectural roofing and siding panel market. It will give you a great product that lasts longer than the traditional galvanized finish. The corrosion resistance of it will make this the ideal product for almost any application, by marrying the lightweight aspect and advantage of zinc coating and the paint, with less chance of the material corroding at the normal stress points, and areas where rusting can start.
2. Prepainted Galvalnized Steel Roof Sheet main structure:
It is carbon steel sheet coated with zinc coating and paint 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. Application scope:
It 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. Main features:
1)Combine the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc and paint.
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)It is widely used as walls or roofs for factories, warehouses, garages, exhibition centers
5. 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.
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.
5)Place the second metal sheet alongside the first with an overlap of 3 to 4 inches (10 cm).
6)Nail the second metal sheet to the roof.
7)Continue with the other sheets, overlapping on every side of each sheet except for at the edges of the roof.
8)Secure ridge caps to the bottom lip of the roof.
9)Test roof for any loose spots or places where water can seep in.
