The 3003 aluminum sheet for roofing offers excellent formability, corrosion resistance, and weldability. Common tempers for 3003 roofing sheets include H24 and H26. The tensile strength of 3003 aluminum plate typically ranges between 160 and 170 MPa in the H24 temper, which is about 20% higher than that of the 1060 and 1100 aluminum series. It is considered an aluminum sheet and strip product with relatively low tensile strength among alloyed aluminum plates.

Surface treatment on 3003 aluminum corrugated sheet.
Anti-corrosion treatments
Galvanizing, coating, and anodizing are examples of anti-corrosion treatments that increase corrosion resistance.
Surface Coating
To improve the appearance, weather resistance, and protection performance of aluminum corrugated sheet, the surface can be coated with polyester, fluorocarbon, or polyurethane.
Mechanical Treatment
The appearance and texture of 3003 aluminum corrugated sheet can be improved by polishing, sanding, and brushing.
Printing and Painting
The surface of the aluminum corrugated sheet can be printed and painted to satisfy individual design needs or for advertising purposes.
The 3003 aluminum sheet features a smooth surface, good plasticity, and high pressure resistance, making it suitable for stamping parts, molds, cans, and shells, including battery casings for lightweight vehicles, cookware, food storage equipment, roofing, transportation facilities, tanks, warehouses, and sheet metal pressure vessels and pipelines.
The specifications and pricing of the 3003 aluminum roofing coil are as follows: available in tempers such as H24, H26, and H16, with thicknesses ranging from 0.6mm to 1.3mm and widths between 55mm and 1600mm. It comes in a wide range of colors, typically coated with PE or PVDF paint. Anodized finishes are less common, as the anodizing effect of this alloy is not ideal.
The 3003 aluminum roofing sheet provides numerous advantages, including corrosion resistance, attractive appearance, light weight, high strength, easy processing and forming, and excellent recyclability. It is widely used in airport terminals, aircraft maintenance hangars, train stations, transportation hubs, exhibition and convention centers, stadiums, public buildings, shopping malls, industrial facilities, and residential houses. Increasingly, both construction enterprises and individual users are choosing aluminum roofing for its superior performance.
With a density only one-third that of steel, the 3003 aluminum roofing sheet offers a service life of up to 15 years, whereas traditional iron roofing often begins to corrode after only a few years of use.
