Forge-welded Gratings

Forge-welded gratings have a high load-bearing capacity and, due to the twisted crossbars, a high slip-resistance. The forge-welded gratings are produced by Lichtgitter in the most modern and advanced manufacturing facilities. This ensures quality and accuracy of the highest possible standard.

The forge welding process means the loadbearing bars are not weakened, and the twisted or round cross bars are pressed under high pressure in a single operation simultaneously, and fully welded electrically.

The gratings can be delivered in many different materials and dimensions. Gratings can be provided as Offshore gratings, maintaining 20 mm ball requirement according to NORSOK.

We are happy to assist with specialized solutions for your needs. Standard types are available for express production, more information here.

Characteristics

  • Absorption of high horizontal forces by pressing and welding of all intersection points
  • High resistance
  • High bearing capacity, because bearing bars are not weakened by welding of cross bars
  • Good torsional rigidity even with subsequently introduced cut-outs – maintenance of the homogeneous unit
  • Increased step security through twisted cross bars

Available Materials:
Hot Dipped Galvanized Steel (S 355 JR/J0/J2)

Pressure-locked Gratings

Pressure-locked gratings are manufactured from steel, stainless steel and aluminum, and can be delivered in different dimensions. Pressure-locked gratings are both functional and aesthetic. Therefore they are often used in the industrial and construction sector, as well as in architectural projects.

Pressure-locked gratings can be used for stair treads, walkways, entrance ways, etc. In specially slotted bearing bars, stable cross bars are inserted. The high pressure and the slit formation of the bearing bars guarantee a secure connection, so that the Lichtgitter pressure-locked grating achieves a warp-resistant structure.

Standard types are available for express production, more information here.

We offer pressure-locked gratings as heavy duty gratings, for e.g. ferry quays, warehouses or other heavy duty applications.

Characteristics

  • Good light and air permeability
  • Countless applications
  • High load capacity at low weight
  • More than 3.500 different pressure-locked grating variants

Available Materials:
Hot Dipped Galvanized Steel (S 355 JR/J0/J2)
• Stainless Steel
• Aluminum
