Checker plate is a type of lightweight metal with a regular pattern of raised diamonds or lines on one side, with the reverse side being featureless. Steel checker plate is usually made by hot rolling, although some manufacturers also make a raised and pressed diamond design.
The added texture reduces the risk of slipping, making checker plate a solution for stairs, catwalks, walkways, and ramps in industrial settings.Its non-skid properties mean that checker plate is frequently used on the interior of ambulances and on the footplates of firetrucks. Additional applications include truck beds and trailer floors.
Checker plate can also be used decoratively, particularly highly polished aluminum variants.
