1100 Corrugated Aluminum Sheet refers to roofing or wall panels made of 1100 aluminum alloy. 1100 aluminum alloy is a corrugated aluminum sheet processed from 1100 pure aluminum, featuring light weight, corrosion resistance, and excellent formability. It is widely used in architectural decoration, industrial equipment, and other fields.
Due to its light weight, seismic resistance, and fireproof performance, it is used for building roofs, wall panels, and decorative purposes. However, its low strength makes it unsuitable for high-pressure applications.
The aluminum content of 1100 aluminum alloy exceeds 99%, making it a relatively low-strength alloy suitable for applications requiring good corrosion resistance and easy machinability but not high strength.

1100 Corrugated Aluminum Sheet Advantages
| Advantage | Description |
| Aesthetic appeal | 1100 corrugated aluminum sheet has a unique visual effect due to its special corrugated structure, making it very popular in decorative applications. The corrugated surface not only enhances the material's three-dimensional and layered appearance but also creates rich reflective effects under different lighting conditions, enhancing its visual impact. Its appearance makes it highly popular for architectural facades, wall decorations, ceilings, partitions, and other designs, especially suitable for modern and industrial-style interiors. Additionally, the decorative nature of the corrugated aluminum sheet makes it an attractive choice for high-end buildings and commercial environments as an exterior element. |
| Lightweight | 1100 aluminum alloy has a low density, making the 1100 corrugated aluminum sheet much lighter than other common metals like steel. This lightweight feature makes it ideal for applications that require reducing the overall structure weight, such as building facades, roofs, and interior wall decorations. Its lightness also makes it easier to handle and install, reducing labor and transportation costs during installation. Furthermore, in applications where structural efficiency and cost savings are important, reducing weight is a very beneficial characteristic. |
| Anti-slip | The corrugated surface of the 1100 aluminum sheet increases friction, improving its anti-slip properties. This feature makes the corrugated aluminum sheet particularly suitable for areas that require anti-slip treatments, such as driveways, walkways, stair platforms, and ship decks. The corrugated structure helps increase the friction coefficient of the contact surface, reducing the risk of slipping accidents. In environments that are wet, greasy, or otherwise slippery, 1100 corrugated aluminum sheet provides additional safety. Therefore, it offers superior safety performance over smooth aluminum sheets in certain applications, such as industrial workshops, warehouses, and outdoor platforms. |
