Metal profile grating


This perforation has a closed surface. It owes its name to the diamond-shaped upward perforations which extend only a maximum of 4 mm upwards. The staggered rhombuses look like flat pyramids and have a size of 24 x 14 mm. They form a visually attractive surface since the light is reflected differently on all four sides of the rhombus. The maximum embossed field is 740 mm.


Metal profile gratings of Graepel-Rhombus perforation are especially suitable as covering for surfaces and platforms in public and industrial areas where closed surfaces are required. Especially recommended is the indoor use. Graepel-Rhombus allows no view through it. It is ideal for places where nothing should drop through and where finer (non-industrial) shoes are worn.

Graepel-Rhombus is, like Graepel-Perl, also suitable for barefoot walking.
