Heavy-duty pressure-locked grating
This product has no standard stock sheet — dimensions and price depend on the drawing or the outline of the structure. Send a DXF/DWG to receive an item-by-item bill and quotation.
NON-STANDARD SIZE
We cut it from a 1000 × 6000 mm sheet with edging and cut-outs for columns. Send a DXF — you will get a bill of materials and a price.

Load-bearing calculator
Permissible load for the selected bearing bar, support span and bar pitch.
Fv — permissible uniform load
31.0 kN/m²
Fp — permissible concentrated load
0.5 kN
Governing criterion: stress. Z = 800.0 mm³, I = 16,000.0 mm⁴.
Simplified version — a simply supported beam model for a single bar, steel E = 210 GPa, permissible stress 160 MPa, deflection limit L/200. An indicative preliminary calculation that does not replace a structural design — the selection is confirmed when quoting.
Questions and answers
Which steel grating for a 1500 mm support span?
For a 1500 mm span and pedestrian loading of 5 kN/m², a 40 × 2 mm or 40 × 3 mm bearing bar in a 33 × 33 mm mesh is used. For forklift loads, individual calculations are required.
How much does 33 × 33 mm steel grating weigh?
Welded grating made of 30 × 2 mm bars in a 33 × 33 mm mesh weighs about 19.5 kg/m². A 1000 × 1000 mm panel is therefore about 19.5 kg, and a 1000 × 6000 mm sheet about 117 kg.
What is the difference between hot-dip and electrolytic galvanizing?
Hot-dip galvanizing gives a 70–85 µm coating and a service life of 25–50 years in corrosivity category C3. Electrolytic coating is 5–15 µm and is suitable only for dry indoor environments.
Do you cut gratings to size with edge banding?
Yes. Cutting to size, flat-bar edging and cut-outs for columns and pipes are made from DXF, DWG or PDF files. The standard lead time is 5–7 working days.
