Cardboard grilles

Cardboard grilles

The advantage of cardboard gratings is that they carry loads with variable directions. These are grilles in which both supporting and transverse flat bars have the same height and thickness. Each flat bar is notched halfway, and then the flat bars are inserted between each other and welded at the joint points.

They are used among others:

  • At storage yards, production halls, warehouses, seaports and airports,
  • In manufacturing plants as bases for water jet or laser cutting
  • in other cases according to individual architectural solutions

We manufacture box and half box gratings (gratings with a lower cross flat bar) from hot-dip galvanized steel, stainless steel and acid-resistant steel.

Cardboard gratings carry heavy loads with variable directions. They are made of load-bearing flat bars with perpendicular notches, in which the connecting elements are placed: flat bars or split bars. The gratings are available in the following versions: with a frame welded to the periphery, higher than the supporting flat bar (the so-called bortices), with angles or anti-slip strips. Also available in stainless steel 1.4301 (304) or acid-resistant 1.4404 (316L) according to DIN 24537.

Cardboard gratings the most common application:

  • Storage yards, in production halls and warehouses,
  • At seaports and airports.
  • Fillings for balustrades, railings or balconies,
  • covering of building facades,
  • Ceiling nets, elevations,
  • suspended ceilings,
  • emergency roads,
  • gratings for the substructures of waterjet or laser cutting machines.

Material – hot-dip galvanized steel (grades S235, S355), stainless steel, acid-resistant steel (grades 1.4301 and 1.4404)
