Colored aluminum roofing sheet are the main type of aluminum roofing panel because the coating makes the panel more corrosion-resistant and beautiful, and the main colors of the coating include red, blue and gray. Most aluminum roofing corrugated sheet can be considered as another product of colored aluminum sheets or rolls. Therefore, in general, the price of aluminum roof panels is higher than that of ordinary roof panels. As an economic roofing material, aluminum roofing sheet are more and more widely used in the construction industry.

The main alloys of aluminum roofing sheet are AA3004 and 5052. AA3004 contains aluminum, manganese and magnesium, with medium strength, weather resistance, good stain resistance and excellent technical properties. It is believed that this is the ideal material for designing roofs for half a century or more. If you need a large-span so-called aluminum roof panel, it is best to choose 5052, which has excellent corrosion resistance and can be used as a shipbuilding material.

The coil made of a long-span aluminum roofing sheet has the following characteristics.

1. Large square and low density. The density of aluminum is 2.73 g / m3, which is only one third of that of steel, which means that aluminum roof panels of the same size are much lighter than steel roof panels. This significantly reduces the load on the building and increases the cost of aluminum roof panels.

2. Sheet rolls have better strength and higher hardness than similar products, and by adjusting the composition and processing methods, they become more and more tough.

3. Colored aluminum roofing sheet panels show high corrosion resistance and corrosion resistance in the chemical corrosion environment of acids, alkalis and salts.

4. Thin sheet rolls are suitable for various surface treatment methods, such as anodizing, electrophoresis, chemical treatment, polishing and coating. PVDF and PE coatings are rich in color and have a long service life, and the surface of the board becomes new again after rain.

5. The sheet has good conductivity and low sensitivity to sparks, which can prevent electromagnetic interference and reduce flammability under special conditions.

6. Large-span aluminum roofing  sheet can be conveniently used in construction. The product can be directly nailed, drilled, sawed, planed, leveled, and easy to process special forms of roofs, such as exterior walls and curved windows. Aluminum metal can be connected by riveting, welding, gluing, etc.

7. The coil span of aluminum roofing sheet  board is large, which is convenient for construction. They can be directly nailed, drilled, sawed or planed, and can be connected by riveting, welding, gluing, etc.

8. The sheets are waterproof, windproof and fireproof. It can be used at an angle of 15 to 90 degrees and can withstand strong winds.
