Two surfaces are available: slotted-smooth and anti-skid. Anti-skid is the ideal choice when safe walking conditions are important. Die-formed teeth in the transverse ribs give you 360°'s of shoe gripping traction even when the grating is wet, oily, muddy, or icy.

Product Features:

  • Exclusive anti-skid design provides 360° of slip resistance
  • Superior ultimate-load performance tested in accordance with AISI standards
  • All sections made from structural grade steel
  • Roll-formed design provides superior strength
  • Optional heel-toe side and end plates
  • Open design prevents build-up of water, grease, oil, and small debris

Project Versatility:

  • 6" and 9" plank widths allow design in 3" increments
  • Standard lengths of 20', 24' and special lengths up to 30', provide excellent design flexibility
  • Choice of smooth or anti-skid surfaces
  • Three leg heights, and material gauges meet a wide range of load, space and budget requirements.
  • Planks are lightweight and install fast by one person. Another advantage is that planks are corrosion resistant galvanized steel.
