Heavy-duty gratings
Heavy-duty gratings have the strength to bear extreme weight. Their fast assembly over large areas, makes them particularly suitable for vehicle access areas.
Materials According to DIN EN 10025
- S 235 JR (ST 37-2)
- S 255 JR (ST 52-3)
Banding types
Overall height/constructional depth
- 30-60mm T-section band
- 70-120mm Flat/shallow band
Anti-slip versions
Serrated bearing bars, serrated cross bars, serrated bearing and cross bars.
Surfaces
hot-dip galvanized, non-galvanized
Heavy-duty gratings in all sizes.
At GI-RO Technik you can obtain heavy duty gratings for every type of application. Choose your required dimension and version from our range.
Load contact area
The areas affected by a defined load, are referred to as load-contact areas. With vehicle access gratings, the load contact areas are the vehicle’s wheels.
Point load
Fp expresses the point loading situation according to the associated load contact area. The deflection (sag-point) that results from the load effect is represented by f (mm).
Braking Factor (Vibration coefficience)
In order to calculate the brake-load, the point load is multiplied according to DIN 1055-3 with the factor Phi (1,4).
Load arrangement
Please note: Depending on the direction of travel, the load contact area changes position and therefore also the number of load-bearing bars required.
Anti-slip versions
The serration of bearing bars necessary for the anti-slipping function, reduces the load-bearing capacity of the anti-slip grating. Exact load values are available on request.

Load capacity table
Gratings are stable construction elements that can bear heavy loads. The load values are derived from the version and dimension of the grating. You can refer to these values in the load value table.
