Cardboard gratings in the E-Invest range carry heavy loads, with variable directions, and retain their original shape. They owe their solidity and strength to supporting flat bars with perpendicular notches, in which only the connecting elements are placed. Cardboard grating has a wide range of practical applications, and thanks to its availability in various equipment versions, it becomes versatile in use. A distinction can be made between steel gratings with angles, with a frame, or with a support element higher than a flat bar, and plates with anti-slip strips. There are gratings made of stainless steel or acid-resistant sheet metal.

Most often cardboard gratings are used for:

  • arranging emergency routes,
  • construction of ceiling grids of elevations,
  • suspension of ceilings,
  • covering facades of buildings,
  • filling balustrades, railings or balconies,
  • creation of sun screen,
  • making ceiling grid, facade grid,
  • building laser or waterjet cutting machines.

Cardboard gratings are folding gratings, in which the supporting and transverse flat bars are of equal height and thickness. They can be used in the form of bridge gratings, wema gratings or stair treads.
