Metal profile grating


Graepel-Open is a C-shaped, canted metal profile grating. Its surface is dominated by large, debossed holes (d = approx. 36 mm) that are surrounded by small embossed holes (d = 4 mm). The perforation extends only slightly upwards. The open area is approx. 50 %. Graepel-Open offers an extremely wide displacement space and excellent drainage; a certain slip resistance is also provided. The maximum embossed field is 810 mm.


Graepel-Open perforation has been designed for catwalks on containers and cars. The large open area ensures a good discharge of precipitation. Slip resistance ensures underfoot safety for the people on service and inspection platforms. Graepel-Open can be used as an alternative to open mesh flooring and provides an additional slip resistance.

Program-controlled Perforations
  • This perforation is program controllable. Thus, individual embossings can be created.
  • The standard edge perforation may be omitted.
