Heavy-duty gratings –
for high-impact tasks

GI-RO heavy-duty gratings are the right choice for all areas experiencing car, lorry, construction machinery or forklift traffic. During the manufacturing process, we can control the dimensioning and thus the load-bearing capacity of the gratings as required to suit your application.

Ideal in settings where heavy loads are moved, such as pit covers, car wash halls and covers for entrances and access roads.

Heavyweight champion!

  • Extremely high load-bearing capacity
  • Can be driven on
  • Air, light and water permeability
  • Durability and weather resistance

Technical information

Structure of a GI-RO heavy-duty grating

Heavy-duty gratings consist of parallel bearing bars into which flat steel crossbars are pressed during the manufacturing process.
For a grating height of up to 60 mm we use our T-profile; for a grating height of 70 mm and more, we use flat steel as edging.

Bearing bar and crossbar types and mesh pitches

Cleverly combined: All features mentioned can be combined to a certain extent. Would you like to know which gratings we can produce for you? Then please contact us. Our sales team is looking forward to meeting you.

Bearing bar and crossbar types
Bearing bar thicknesses (mm) Bearing bar heights (mm)
4,0 / 5,0 30-60 (in 5 mm intervals)
5,0 70-120 (in 10 mm intervals)
Maximum production lengths
Bearing bar (mm) Crossbar (mm)
3000 1500
Mesh pitch
Bearing bar spacing (mm) Crossbar spacing (mm)
18,00 17,00
And we also offer multiples of this pitch, but not exceeding 72.00 x 85.00 mm

Materials and surface finishes

Depending on the intended use, our gratings are made with different materials and are delivered with various surface finishes. As standard, the heavy-duty gratings are manufactured in S235JR steel and are hot-dip galvanised in accordance with DIN EN ISO 1461. For quantities of 25 m² or more, these can also be made in the harder S355JR steel grade.

Slip resistance

Dirt, oil, grease or water on floor coverings that can be walked on or driven over always means an increased risk of slipping. Thanks to our gratings with special slip resistance, you can still enjoy reliable grip in all situations. Our heavy-duty gratings offer high slip resistance by means of varying recesses in the bearing bars and/or crossbars. Depending on the profile, our gratings thus meet the requirements of the  R10 to R11 rating classes.

Load values

Heavy-duty gratings are extremely stable construction elements that can bear very heavy loads. The respective load values depend on the design and the clear span. The load-bearing capacity can be adjusted according to your wishes by changing the bearing bar spacing and the bearing bar type. You can look up the load values for cars, trucks or forklifts in the load tables, which you can download here: Download Load Table
