Products Description
Aluminum Corrugated Roofing Sheets
Aluminum Corrugated Roofing Sheet is a very cost-effective roofing and exterior wall material. Aluminum alloys are widely used in the construction industry, and play an important role in the development of modern buildings in the direction of comfort, lightness, durability, economy, and environmental protection.
These aluminum roofing sheets are used PE roller coating. The advantage of PE roller coating is that the film hardness is higher, and the price is cheaper than fluorocarbon coating. But the durability is slightly worse than fluorocarbon coating, but it is also much longer than color steel plate. If the climate environment is not so harsh, or it is used indoors, PE roller coating is also a good choice.

Corrugated roofing sheets is a very cost-effective roofing and exterior wall material. Aluminum alloys are widely used in the construction industry, and play an important role in the development of modern buildings in the direction of comfort, lightness, durability, economy, and environmental protection.

The reason why slate grey metal roof panels has such excellent durability is that when the aluminum plate is in contact with the atmosphere, a layer of aluminum oxide film will be formed on the surface of the aluminum plate, and this oxide film will protect the inner aluminum plate from further corrosion. This oxide film has good chemical resistance and is therefore suitable for industrial buildings, areas with high air pollution or marine climates.
Advantages Of PE Or PVDF Coated Al Alloy 3003 And 3004 Corrugated Roofing Sheets:
1: Strong corrosion resistance, the aluminum plate itself has self-rust resistance, the formed oxide layer can prevent metal oxidation and corrosion, and has good acid and alkali resistance. Combined with the paint coating, the service life is greatly increased;
2: Good plasticity and easy processing;
3: Light weight, can reduce the problem of large load bearing roof structure
4: Good electrical conductivity. Non-magnetization and low spark sensitivity can prevent electromagnetic interference and reduce flammability in special environments. :
5: Low comprehensive use cost and environmental protection, 100% recyclable;
PVDF is fluorocarbon paint which is a high-performance two-component coating with excellent physical and chemical properties. Fluorocarbon paint has the advantages of weather resistance, self-cleaning, corrosion resistance, solvent resistance, color retention and gloss retention, etc. The paint film has various colors , including solid paint and metallic flash paint. The fluorocarbon paints we use are all high-quality paints higher than 70% fluorocarbon.
