WOLFA Gratings

We manufacture our pressure-locked gratings according to DIN 24537 and hot-dip them against corrosion according to the DIN 50976 standards. They are made at our Görschen site on our state-of-the-art computer-controlled production lines. The cross bars are force-pressed into the grooved bearing bars. The bearing bars guarantee the carrying capacity while the cross bars maintain the mesh structure and assure uniform load distribution. The pressing and hot-dipping processes render the encased gratings extremely robust and stable. The pressure-locked gratings are available in a variety of mesh sizes, installation heights and material strengths to fit all areas of application. You can choose from:

The innovative WOLFA pressure-locked grating provides very specific advantages over other grating systems.

  • the optimized grating frame profile guarantees perfect stability
  • notches and cutouts do not affect the strength of frame or bearing bars
  • the specially developed, rounded frame profile enhances the bearing bar load capacity
  • the grating frame profile is absolutely free of folded edges; the gratings remain clean, dirt cannot deposit and cause corrosion
  • the WOLFA grating system comes in all heights and sizes and can be ordered with or without casement

*all dimensions in mm. Listed sizes = outer casement dimensions. The grating is approx. 10 mm smaller than the outer casement dimension. The smaller dimension is the bearing bar direction. For permanently high loads, e.g. pedestrian traffic, we recommend mesh size 30/10. Special dimensions upon request.

Special gratings

We also customize our gratings to our clients’ individual requirements. Please provide the following information in your inquiry:

- exact dimensions (length x width or bearing/cross bar dimensions)
- grating height (20, 25, 30 or 40 mm)
- bearing bar dimensions if the bar needs to be larger than the cross bar
- mesh size 30/30 or 30/10
- information on load capacity (for pedestrians, for cars),
If possible, surface load per square meter or
single load on load surface 200 x 200 mm
- smooth or non-slip design
- grating bearing side

Maximum grating sizes:

Bearing bar up to 1000 mm: 1000 x 2000 mm
Bearing bar up to 1500 mm: 1500 x 1800 mm
Larger bearings are produced in several parts
