Checker plate
When checker plate is referred sheets (steel, stainless steel, aluminum or the like) with diagonal ribbed structure. This is primarily used to improve slip resistance , and it is also used as an ornament . The corrugation is in the manufacture of the sheet by high strength of metal forming rolls applied and can not be produced by subsequent stamping.
Over time, other shapes and structures have been created that serve the same purpose. So-called teardrop plates, checker plates, lens plates (in the picture: 5-fold lens plate) are very common. Depending on the type of sheet metal, these are one to five tapered ribs, arranged as an offset checkered pattern.
Checker plate is known historically as a floor covering, often also in vehicles. Aluminum sheet is used for this because it is lighter. The tapered ribs on the surface increase the slip resistance, especially when wet. Because of its slip resistance and robustness, checker plate is also suitable for building ramps and stairs.
Because of its robust appearance, the characteristic pattern is now also used in a similar form on handbags, table foils and other items.

Checker plates and checker plates made of steel are standardized in Germany in the DIN standard DIN 59220. According to this standard, checker plates are identified in the order information with the code letter "R", checker plates with the code letter "T". Steel sheets are standardized in the thickness range from three to ten millimeters.
Aluminum sheets with rolled-in patterns are standardized in the European standard EN 1386. A distinction is made here between the pattern types “duet”, “quintet”, “diamond”, “barley grain” and “almond”. Sheet metal thicknesses are standardized here in the range from 1.2 to 20 millimeters.
