1. PPGI Corrugated Roofing/Color Steel Roof Sheet introduction:
Prepainted Galvalnized Steel Roof sheet is one of the most corrosion resistant corrugated materials offered in
the architectural roofing and siding panel market. Prepainted Galvalnized Steel Roof sheet will give you a great
product that lasts longer than the traditional galvanized finish. The corrosion resistance of this Prepainted
Galvalnized Steel Roof sheet will make this the ideal product for almost any application, by marrying the light
weight 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.PPGI Corrugated Roofing/Color Steel Roof Sheet main structure:
Prepainted Galvalnized Steel Roof 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 Galvalnized Steel Roof sheet application scope:
Prepainted Galvalnized Steel Roof 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. PPGI Corrugated Roofing/Color Steel Roof 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)Prepainted Galvalnized Steel Roof sheet is widely used as walls or roofs for factories, warehouses,
garages, exhibition centers
5. PPGI Corrugated Roofing/Color Steel Roof 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.
5)Place the second metal sheet alongside the first with an overlap of 3 to 4 inches (10 cm). Secure the
sheets together using hex screws and washers. Whenever possible, line up the ridges of each metal sheet,
creating a tighter roof and make it easier to drill in the screws. Screw in the spaces between where you
nailed the first sheet to the wood.
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. Follow the same method as when installing metal sheets:
Overlap the ridge caps both with each other and with the sheets, using hex screws and washers where the
metal overlaps and nails where the ridge caps attach to wood. You will use 40 nails for each length of ridge cap.
9)Test roof for any loose spots or places where water can seep in. If any roofing is sticking up, secure it as
much as possible with nails or screws if attaching it to other metal sheets.
10)Paint the corrugated roof, if desired.
