Diamond Pressed/Checker Plate/Diamond Embossed Roll for Corrugated Roofing

Product Description

1. Diamond Embossed Corrugated Roofing Sheet brief description
Diamond Embossed Corrugated Roofing Sheet is also called pre-painted panel roofing, which is formed by cold roll forming machine, using the color steel coil or aluminum steel as the base materials. It is featured with easy installation, high strength, more economic, (low lost ). It is widely used as the wall or roof of factory, warehouse, garage, exhibition center, cinema etc.

2. Diamond Embossed Corrugated Roofing Sheet raw materials
Galvanized steel, Galvalume Steel, Galvalume Pre-painted sheet and aluminium sheet

3. Diamond Embossed Corrugated Roofing Sheet technical parameters
1. Light weight: 10-14 kg/square meters, equivalent to 1/30 of the brick
2. The coefficient of thermal conductivity: λ < = 0.041 w/mk.
3. High strength: The colorful steel can be made as structure bearing plate because it has good subtractors of bending resistance and outer pressure resistance, so generally, the prefab house don't use the beam column.
4. Bright color: The prefab house don't need the surface decoration, the color sheet has good anti-corrosion layer, which can use at least 10-15 years.
5. Installation flexibility: Construction period can be reduced by more than 40%

4. Diamond Embossed Corrugated Roofing Sheet main features
1) Can prevent roof from the damage of excessive moisture and strong winds.
2 It is attached to wood or metal trusses with steel nails or screws that have character of heat-resisting, corrosion resisting and ageless.
3)Light, strong, corrosion-resistant, and easily transported
4)High percentage of recycled material, can reach 90%.

5. Diamond Embossed Corrugated Roofing Sheet packing details
1)water proof paper covered with steel sheet on the top of products; Bundle by steel strip with iron pallet.
2)water proof paper covered by whole steel sheet; Bundle by steel strip with iron pallet.

6. Diamond Embossed Corrugated Roofing Sheet installation instruction
1)Prepare the roof surface by removing any old roofing, any rotten wood, and adding roofing felt to the entire surface.
2)Calculate the number of color metal roofing sheet 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 (or 10 cm). Secure the sheets together using hex screws and washers. Whenever possible, line up the ridges of each metal sheet. This will create 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.
