1. Prepainted Galvanized Metal Roof Tile introduction
It is produced by direct application of a paint (after applying a treatment and, in most instances, primer)
onto steel sheet in a coil-coating line. Coil-line painting can be used to apply a paint coating directly on uncoated steel sheet or on metallic-coated steel sheet. For maximum corrosion resistance, coil-line
painting is often done on metallic-coated steels including galvanized, galvalume and terne coated sheet


2. Prepainted Galvanized Metal Roof Tile application scope
Color steel roofing sheet is most commonly used for commercial, agricultural, and industrial purposes,
however, it is now also being recognized as an excellent form of residential roofing. Galvanized roofing
sheet is also known used as sinusoidal, corrugated iron or wriggly tin


3. Prepainted Galvanized Metal Roof Tile 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) Widely used as walls or roofs for factories, warehouses, garages, exhibition centers


4. Prepainted Galvanized Metal Roof Tile installation tips
1) Prepare the roof surface by removing any old roofing, rotten wood,adding roofing felt to 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 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
