Lichtgitter was founded in 1929 by Carl Martin and Allan Norman Kennedy as a company specialising in the production of gratings.

The company is now run by the family in 3rd generation and is still 100% owned by the founding family Martin.

Continuous performance and quality development as well as innovative manufacturing techniques, combined with prudent and market-driven corporate orientation have made Lichtgitter a leading manufacturer of pressure-locked gratings, forge-welded gratings and perforated metal planks with subsidiaries and joint ventures throughout the world.

Today's portfolio also includes GRP gratings, chequer plate blanks, spiral staircases, stair treads, ladder rungs, galvanising as well as steel service. For all these products, we also offer a comprehensive service package.

  1. 1929

    Lichtgitter GmbH is founded in 1929 as a company specialising in the production of gratings.

    An English entrepreneur looks for a good production site for his business idea to develop floor coverings which are permeable to light and where dirt and grime can fall through. By chance, he is alerted to an empty production facility in Stadtlohn which belongs to the Martin family. 

    The production initially focuses on the production of patented welding gratings with honeycomb mesh.

  2. 1945

    Complete destruction of the production facility in 1945 during World War II. Reconstruction follows in the next few years.

  4. 1956

    The production expands. The manufacture of plug grating is added.

  5. 1961

    In 1961 the improved construction of the pressure locked gratings was added to the production. This product is today a fixed element in the production.

  6. 1966

    Start of production of forge-welded grating. This technique, developed largely by Lichtgitter-Gesellschaft brought the largely automated production of forge-welded grating products to a new level of development.
