Colorful Iron Roofing Sheet/Prepainted Galvanized Metal Roof Tile

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. It will give you a great product that lasts longer than the traditional galvanized finish. The corrosion resistance of this corrugated sheet will make this the ideal product for almost any application, by marrying the lightweight aspect and advantage of zinc coating and painting, 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 and painting 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. It 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 zinc coating and painting.

2)Preferred product for long-term resistance to atmospheric corrosion

3)The superior corrosion resistance is achieved by the presence of microscopic zinc-rich and painting-rich areas within the coating.

4)Easy to install, high strength and lower costs

5)Prepainted Galvanized corrugated sheet is widely used as walls or roofs for factories, warehouses, garages, exhibition centers etc.


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.

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.
