Graepel-Metric is a C-shaped, canted metal profile grating. Its perforation is a variant of Graepel-Universal: The hole diameters are the same (upward d = 7 mm and downward d = 14 mm), the lengthwise divider is 30 mm (40 mm with Graepel-Universal). The grating width can be realized in stages of 25 mm (30 mm with Graepel-Universal). This smaller hole spacing gives this perforation a different look, functionality and properties. It looks light and transparent and with 32 % at the maximum embossed field of 475 mm, it has also a larger open area than Graepel-Universal. Graepel-Metric has also high anti-skid values as well as a good drainage effect.
The denomination follows the primary use in the industrial sector: Due to their width divider, metal profile gratings of Graepel-Metric perforation are especially suitable to cover surfaces that have at least one metric side length with standard gratings. There are no fitting gratings required which must be specially manufactured as special gratings for other perforations.
Ladder rungs are also available in Graepel-Metric perforation.
