Metal grating

pressedpress weldedwelded

Product information
The classic press welded grating is manufactured with twisted square bearing bars for improved slip resistance. Where aesthetics are prioritised, smooth round cross bars can be used as an alternative. The smooth-round version is available for the common mesh spacings listed below.

Characteristics / technical specifications

• Product type: Press welded grating with option of smooth round cross bars (alternative to twisted square cross bars).
• Manufacturing method: Press welded (bearing and cross bars welded at intersections).
• Cross bar options: Smooth round bars for aesthetic finish; twisted square bars for greater slip resistance.
• Compatibility: Smooth-round cross bar version possible for the common mesh spacings listed above; some combinations marked * are available with restrictions.
• Standard bearing bar profiles: profiles 25, 30, 35, 40, 45, 50, 60, 70, 80 with thicknesses 2–5 mm as shown.
• Accessories: multiple fixing and clamping systems available (welded-in plates, clamps, butt joints, Hilti clamp).
• Notes: For welded-in plates hole size per customer specification; screws typically by the customer.
