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.
Characteristics
- Good light and air permeability
- Countless applications
- High load capacity at low weight
- More than 3.500 different pressure-locked grating types
- Various materials possible
All characteistics can be combined. Please contact us to check the producibility of the gratings. Our sales department is always at your disposal.
If a serration class > R10 is required, the bearing bars of the gratings can be punched on the upper side in a special process.
