LICHTGITTER - Perforated metal planks
Quality prevails

Perforated metal planks are C-shape profiled and bent construction elements. They are manufactured on CNC punching machines and roll formers. The application options of perforated metal planks are varied. They can be used as work platforms, ramps, façades, grandstands, 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 installations

  • Considerable production lengths up to 393 11/16"


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.

Material + Surface treatment

The most economical corrosion protection for perforated metal planks is hot-dip galvanizing. Further surface treatments such as, e.g. powder coating are also possible.

Hot-dip galvanizing

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

Galvanized and bituminized

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 durability of our products even in highly loaded areas.

Galvanized and powder-coated

"Two is better than one!" especially applies 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. The life expectancy can be increased in the range of 1.2 to 2.5, depending on the system. This increased solution is invaluable for external applications such as facades etc.


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.


The anodizing process is a method of surface technology used to produce a protective oxide layer on aluminum.

Anodizing is typically used in decorative areas to give the aluminum a uniform appearance. Moreover, different color shades can be achieved according to the EURAS color fans.

Slip resistance

Under certain framework-conditions, the issue of "anti-slip" should not be disregarded when selecting a suitable floor covering.

The correct anti-slip protection for the floor covering should already be established in the planning phase.
