Long Span Aluminium Roofing Sheet

Long span aluminum roof sheets are a lightweight, high-strength roofing material widely used in modern buildings. They not only provide good waterproofing, heat insulation and soundproofing, but are also the choice for many large-scale construction projects because of their light weight and high corrosion resistance. Due to the lightweight and high-strength properties of aluminum, aluminum roof sheets can be designed for longer spans, reducing the number of supporting structures and simplifying the installation process.

Long span aluminum roofing sheets mainly include aluminum-magnesium-manganese alloy sheets, aluminum-zinc alloy sheets and other types. Among them, aluminum-magnesium-manganese alloy sheets are widely used for their excellent corrosion resistance, strength and plasticity. Its design and material properties enable it to withstand long-span structures with good waterproof, heat insulation and corrosion resistance.

- Aluminum alloy grades: Commonly used are 3003, 5052, 6061, etc. Different grades of aluminum alloys have different strength and corrosion resistance.

- Thickness: The common thickness ranges from 0.5mm to 2.0mm, depending on the load bearing capacity and usage environment.

- Width: usually between 500mm and 1200mm, the specific size can be customized according to customer needs.

- Length: generally can be customized according to the actual demand, common 6m, 9m, 12m and other standard lengths.

- Coating type: PVDF (polyvinylidene fluoride), PE (polyethylene), SMP (silicone-modified polyester), etc. Different coatings have different weather resistance and corrosion resistance.

- Color: A variety of colors can be selected to meet the needs of architectural appearance design.

- Wave distance: i.e. the distance between the crest and the wave, common ones are 210mm, 300mm, 350mm, etc.

- Wave height: the height of the wave crest, common 25mm, 35mm, 50mm, etc.

- Rib height: i.e. the height of reinforcing ribs, which is used to increase the rigidity and bearing capacity of the board.

Features of aluminum sheet long span for roofing:

- Corrosion resistance: Aluminum metal has good corrosion resistance and can resist the erosion of many chemical substances.

- Aesthetics: Aluminum roofing sheets are available in a variety of colors and textures to meet different architectural styles and aesthetic needs.

- Light weight: Compared with other metal materials, aluminum roofing sheets are lighter in weight, making them easier to transport and install.

- High strength: Aluminum roofing sheets have high strength and rigidity and can withstand large loads and wind.

- Easy to process: Aluminum roofing sheets are easy to cut, bend and weld, and can meet the needs of various complex shapes and sizes.

Long span aluminum roofing sheets are widely used in the roofs of various large buildings, such as airport terminals, railway stations, large shopping centers, stadiums, conference and exhibition centers. These buildings usually have large roof areas and complex structural requirements, which can be met by long span aluminum roof sheets that provide good waterproofing, heat preservation and aesthetic effects.

Long-span aluminum roofing sheets are an ideal building material for construction projects that require large space, light weight and aesthetics. The application of aluminum roofing sheets will become more and more widespread as the construction industry continues to improve material performance and environmental requirements. Choosing the right aluminum roofing sheets can effectively enhance the performance and longevity of a building while meeting the aesthetic demands of modern architecture.
