Graepel Gratings

for safety underfoot

Metal profile gratings are C-profiles canted from metal sheet cuts with structured surface. Metal profile gratings offer the highest load capacity and a low dead weight. This gives them significant advantages over open mesh flooring in steel construction because less substructure is required due to the load capacity in the longitudinal direction. Metal profile gratings are available in steel, galvanized steel, stainless steel and aluminum.

Intelligent design of fastening solutions ease the connection of gratings and to substructures.


Metal profile gratings provide underfoot safety. They are ideal as coverings for walkways and platforms, stairways, ladder rungs and steps. Architects are increasingly discovering the aesthetic charms of the perforations and their durability. Metal profile gratings can also be used as enclosures and covers for machinery.

In order to make it easier to select the specific perforation for the intended purpose, we have renamed some of our perforations. The previous names are given in brackets on the corresponding sub-pages.


Graepel metal profile gratings have the following characteristics:

  • Slip resistance is realized by upward embossment.
  • Drainage is possible through downward perforation.
  • The change between upward and downward beads creates different surface patterns – hereinafter referred to as “perforations”.
  • Stability in longitudinal direction is created by the C-profile. The possible loads are dependent on edge height, inner edges, perforation and the chosen material. The lateral load capacity of the gratings is determined by material thickness and perforation.
  • By default, the metal profile gratings have a system perforation (edge perforation) on the long side of the beveled edge which facilitates the mounting of the gratings.
  • Even gratings with unperforated edges on one or both sides are possible.
  • Some of the Graepel perforations are program controllable. This means that unperforated areas are also possible in the surface pattern where holes or cut-outs can be placed later. Program control also allows an adjustment of the perforations to a contour.
  • All Graepel metal profile gratings are also available as flat cuts without folded edges. These plates have a slightly curved finish.
  • We are at your disposal for further technical queries.

We distinguish perforations for 3 fields of application:

Public sector

Industrial sector

Special perforations

We have grouped 7 perforations together which are especially suitable for indoor/outdoor use in public areas.


These gratings can also be used in the industrial sector where smaller hole sizes and consequently a smaller open area are required.

  • Holes with a maximum diameter of 8 mm
  • Perforations extended only a few millimeters upwards
  • Accessible with finer shoes, some gratings are suitable for barefeet
  • Slip-resistant surface
  • Lower risk of injury or abrasions
  • Durable
  • Easy to maintain
