Metal profile grating


This perforation has a closed surface. The perforation owes its name to the upwardly embossed stepped cones (diameter of 10 mm at the base). They are arranged in staggered rows, extend approx. 4 mm upwards, and therefore offer a higher displacement than Graepel-Perl. The maximum embossed field is 580 mm.



Metal profile gratings of Graepel-Spikes perforation are especially suitable as covering for surfaces and platforms in public and industrial areas where closed surfaces are required. They are for example used for coverings capable of being walked on, where nothing should drop through, or as cover with optically attractive surface.

Program-controlled Perforations
  • This perforation is program controllable. Each stepped cone can be left out and thus individual embossings can be created.
  • The standard edge perforation may be omitted.
