Aluminium Diamond plate, also referred to as deck plate or floor plate, is a product that has a raised pattern or texture on one side with the reverse side being smooth. The diamond pattern itself can vary, as can the height of the raised area. Diamond plate is most commonly used on metal stairs to provide increased traction.

The raised bumps on the surface of the plate increase the friction between a person's shoe and the surface of the plate reducing the chance of someone slipping on the walking surface. For this reason, diamond plate is a type of non-slip walking surface. 

Aluminum diamond plate is corrosion resistant. Because of its ability to withstand the elements, aluminum deck plate is often found in outdoor settings such parking lots, loading docks and stairs. It is also used on boats, docks or other marine applications. Because diamond aluminum plate is easy to wash and keep clean, it can be found in kitchens, restrooms and walk-in refrigerators or freezers. Aluminum floor plate can also be used for a decorative purpose and is available in a variety of patterns and finishes.
