Heavy duty gratings
When correctly dimensioned, Lichtgitter heavy duty gratings are suitable for carrying extremely high loads and are mainly used in trafficable areas.
Pressure-welded gratings are particularly suitable as a heavy-duty grating. Depending on static or dynamic loading, heavy duty gratings can be manufactured for many applications depending on the clear span. We recommend that you allow our experienced structural engineers who are familiar with the product to calculate special load cases.
Characteristics
- high load capacity
- good light and air permeability
- different pitches and bearing bar heights possible
- additional serration on request
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.
