Advantages of using aluminum sheets include their lightweight nature, which reduces transportation and handling costs. They are also corrosion-resistant, making them suitable for outdoor applications. Aluminum sheets are recyclable and environmentally friendly, with a high recycled content rate. They are also easy to fabricate and can be cut, bent, and shaped into various forms. Disadvantages include lower strength compared to steel, which may require thicker sheets for certain applications. They can also be more expensive than some other materials, and their light reflection can sometimes be a concern in certain environments.
