Forge-welded Gratings

Continuous development at Lichtgitter has resulted in the most modern and advanced manufacturing facilities, ensuring the quality and accuracy of forge-welded Grating products are 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.

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:
• Carbon Steel S 355 JR/J0/J2

Pressure-locked Gratings

Apart from the use in the industrial and construction sector, Lichtgitter gratings are also increasingly used in architectural applications. Pressure-locked gratings are manufactured from steel, stainless steel and aluminium.

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.

The gratings can be delivered in many different materials and dimensions.

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:
• Carbon Steel S 355 JR/J0/J2
• Stainless Steel
• Aluminium
