LICHTGITTER - Perforated metal planks
Quality prevails

Perforated metal planks are C-shaped profiled and bent construction elements. Perforated metal planks are manufactured on CNC punching machines and roll formers. The application options of perforated metal planks are varied. Perforated metal planks are used as work platforms, ramps, façades, grandstands and much more. They are also used as walkways and supply routes, as well as extensive protection mats for workspaces below of conveyor systems.


  • Bridging of large spans
  • Cost reduction on substructures
  • High slip resistance
  • Stable and safe walking and standing areas
  • Different surface profiles
  • Fast and simple installation
  • Considerable production lengths up to 10 m
  • Production
    • Perforated metal planks are manufactured in the following production steps:

      After an examination, the material supplied on coils is fed to the production line.

      • With modern presses and tools, the desired surface profiles are punched and cut the gratings are cut to length.
      • A CNC-controlled roll former rolls the die-cut sheets to the characteristic C-profile shape with the desired height and width.
      • Any necessary notches are inserted according to customer specification and usually edged with an edging in perforated metal plank height.
      • The perforated metal planks are galvanized as standard DIN EN ISO 1461.

  • Material + Surface treatment
    • The most economical corrosion protection for perforated metal planks is hot-dip galvanizing in accordance with DIN EN 1461. The galvanizing is carried out in the groups own galvanizing plants in Stadtlohn, Sulz and Heek. Further surface treatments such as, e.g. powder coating are also possible.

    • Hot-dip galvanizing
    • The term hot-dip galvanizing specifies the process where a zinc coating is applied by immersing the pretreated parts in molten zinc. The zinc coating adheres so firmly to the surface that it does not peel off or crack under normal mechanical stress, e.g. as during transport, walking or even driving on it.

    • Galvanized and bituminised
    • Bitumen dipping is often used in acidic environments because bitumen (Inertol) offers very good resistance to such media. The galvanizing provides an excellent primer for the coating of bitumen, thereby increasing the life of our products even in highly loaded areas.

    • Galvanized and powder-coated
    • "Two is better than one!" applies to a special extent to our duplex special process for the protection duration of our products. Galvanizing and powder coating - the combined corrosion protection properties of both technologies offer a much longer effective system than the respective corrosion protection properties of each individual solution. Life expectancy can be increased in the range 1.2 to 2.5 depending on the system. This increased solution is invaluable for external applications such as facades etc.

    • Pickled
    • Stainless steel is resistant to corrosion through an invisible passive layer. To counteract contamination from mechanical machining and to achieve an effective passive layer, a chemical surface treatment, pickling, is applied.

    • Anodized
    • The anodising process is a method of surface technology for producing a protective oxide layer on aluminium.

      Anodising is typically used in decorative areas to give the aluminium a uniform appearance. Moreover, different colour shades can be achieved according to the EURAS colour fans.

  • Slip resistance
    • When selecting a suitable floor covering, the issue of "anti-slip" must not be disregarded under certain framework conditions.

      The Institute of Occupational Safety (IfA) has described performance criteria for work areas with increased danger of slipping in the BGR 181 instruction sheet. Already in the planning phase, the correct rating group should be established for a floor covering.

      The majority of our products are tested at regular intervals by the IfA and assigned an anti-slip rating group in accordance with the BGR 181.

      We are able to offer you a suitable product for all the rating groups listed in the BGR 181 using various profiles, shapes and coatings.
