Performance and Advantages
Weather Resistance:
PVDF coatings used on the coils have excellent resistance against eco-agents such as acid rain, salty fog, and UV rays ensuring minimal deterioration of appearance or properties over 25 years.Formability:
Thanks to the H32 temper, little springback occurs that allows bending, roll forming, or drawing in various manufacturing processes commonly encountered in roofing or exterior paneling without surface cracking.Easy Fabrication:
Can be welded and riveted effectively after correct surface treatment maintaining structural strength and aesthetics.Light Weight:
Compared to steel sheets, aluminum coils drastically reduce structural load without compromising protection or resistance.
Applications
| Industry | Common Use Cases |
|---|---|
| Construction & Building | Exterior & interior cladding, roofing, façades, soffits, gutters |
