Diamond metal plate can be made in one of two ways – by stamping or by being hot rolled. Both methods use a combination of heat and pressure.

With stamping, room temperature metal is passed between a series of large rollers. One roller is smooth and the other roller features the diamond pattern. The pressure of the metal passing between the rollers allows the diamond pattern to be transferred to one side of the metal. Stamping is commonly used to make aluminum diamond plates.

With hot rolling, the metal is flash heated above its recrystallization temperature using an electronic thermal machine before being passed through the rollers. The molten metal than cools into the diamond plate shape. Heating the metal helps prevent flaws from occurring and is often used to make steel diamond plates.
