LICHTGITTER - Gratings

Many years of experience and continuous performance and quality development, have made Lichtgitter into one of the worldwide leading manufacturers of gratings.

Continuous attention to product development will ensure that the future of Grating types will ensure that Lichtgitter will be among the market leaders in Grating design.


  • Material + Surface treatment
    • The most economical corrosion protection for gratings is hot-dip galvanizing in accordance with DIN EN 1461. Zinc provides very good long-term corrosion protection under normal atmospheric conditions. Other materials such as stainless steel or aluminium require only a passivation to provide long-lasting protection against corrosion. Below, you will find standard anti-corrosion solutions for different metals.

    • 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.
