Diamond plate

As a checker plate is called plates (steel, stainless steel, aluminum, etc.) with diagonal ribbed structure. This serves primarily to improve the slip resistance, also it is used as an ornament.

In the course of time, other forms and structures have been created which fulfill the same purpose.

Most common are the so-called tear sheets, Tread plates, lens plates ( in the picture: 5x lens plate). Depending on the type of sheet steel are the one to five tapered ribs, arranged as a staggered pattern.

The ribbing is applied by high power of forming rollers in the manufacture of the sheet and can not be produced by subsequent stamping.

The checker plate is known historically as a floor covering, often in vehicles. For this, a sheet of aluminum is used for reasons of weight, wherein the tapered ribs on the surface of the slip resistance - especially when wet - increase.

The robust appearance due to the interesting characteristic patterns is, however, used on handbags, table slides and Others in a similar form in the meantime.

Standardization

Checker plate and tears sheets of steel are standardized in Germany in the DIN standard DIN 59220. Checkered plates are called according to this standard in the ordering code with the code letter "R", tread plates with the letters "T". Steel sheets are standardized in a thickness range of three to ten millimeters.

Aluminum sheets with rolled patterns are standardized in the European standard EN 1386. There is a difference between the pattern types " duet ", " Quintet ", " diamond ", " barley grain " and " almond ". Thicknesses here are standardized in the range of 1.2 to 20 mm.
