An aluminum plate is a flat, thin sheet or piece of aluminum, usually of uniform thickness. Aluminum plates have excellent strength-to-weight ratios, which makes them highly desired and commonly used in shipbuilding, automobile manufacturing, military vehicle armor production and many other industries. They may also be used for storage tanks, such as spacecraft fuel tanks. Because aluminum is not weakened by low temperatures, it is especially useful in cryogenic storage applications.Aluminum plates are important utilities in a variety of contexts. In defense contracting, for example, very thick aluminum plates can be used as structural armor in bunker construction, and the same is true in the construction of armored vehicles. Textured aluminum plates are often used as flooring materials, particularly in industrial contexts. For example, in a warehouse loading dock, a strong, chip-resistant surface must be present in truck unloading areas. Such surfaces are often made with ridges or other shapes that increase traction, reducing the risk of worker slippage, injury and product loss. Along with aluminum rods, tubes and sheets, aluminum plates are among the many basic shapes that aluminum suppliers offer to their clients.
