Pressure-locked gratings

Apart from the use in the industrial and construction sector, Lichtgitter gratings are also increasingly used in architectural applications .

Pressure-locked gratings are manufactured from steel, stainless steel and aluminium. Pressure-locked gratings are bound either with flat material, two stiffening corrugations or T-profile. On our flexible production plants, we can manufacture the most varied pressure-welded grating types.
