Products Description
Material :PE or PVDF Coated Al alloy 3003 and 3004
Slate grey metal roof panels is a cost-effective roofing and exterior wall material, which has the advantages of corrosion resistance, beautiful appearance, light weight, high strength, and easy processing and molding. In the follow-up, different coating processes will be combined to bring extraordinary visual effects to the building, and at the same time make the anti-corrosion performance of the aluminum alloy itself more excellent.
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.

PE Or PVDF Coated Al Alloy 3003 And 3004 Slate Grey Metal Roof Panels Has Many Advantages As Follows
1. Light weight: the density of aluminum is 2.73KG/M³, only 1/3 of that of steel;
2. High strength: high strength can be achieved through composition configuration, processing and heat treatment methods;
3. Corrosion resistance: with self-rust prevention ability, the formation of oxide layer, can prevent metal oxidation corrosion, good acid and alkali resistance;
4. Diverse surface treatment, beautiful: anodizing, electrophoresis, chemical treatment, polishing, painting treatment;
5. Good plasticity and easy processing;
6. Good electrical conductivity: non-magnetization and low spark sensitivity, can prevent electromagnetic interference and reduce the flammability in special environment;
7. Easy installation: aluminum metal can be riveted, welded, glued and other ways to connect;
8. Environmental protection: 100% recyclable.
RAL 7015 slate grey is a very widely used color, which can be used on the roof or on the wall. It can be combined with different tile structures to show different effects.
