Roof panels are boards that can directly bear the roof load. They are positioned on the roof of a building and are typically made of materials like aluminum-magnesium-manganese or alloys. After assembly on the gable end rafters at the top floor, the flanges overlap to cover the individual box-shaped roof panels, thus avoiding vertical light gaps and creating a cohesive pitched roof.

Roof panel features:
Lightweight; aluminum has a density of 2.73g/cm³, which is only one-third that of steel.
2. High strength; high strength can be achieved through component configuration, processing, and heat treatment methods.
3. Corrosion-resistant; self-antirust capability, the formed oxide layer can prevent metal oxidation and rust, good resistance to acids and alkalis.
4. Variety of surface treatments available, ensuring aesthetic appeal. Processes include anodizing, electrophoresis, chemical treatment, polishing, and painting.
Good moldability, easy to process.
