Press-welded gratings for shelving

JK Technic press-welded gratings for shelving can be used for pallet racks and grating cantilevers, for storing heavier loads without the need for increased load absorption by the butt joints. Gratings for shelving are manufactured from S235JR steel and are also available with a pressed finish.


Gratings for shelving offer numerous benefits:

  • Provide excellent rigidity and stability for items stored
  • Allows better visibility of items stored
  • Light can get through
  • Water can get through
  • Easy and quick to assemble

Finishes available :

  • Untreated
  • Galvanized
  • Power-coated steel

Depending on your requirements, 4 models can be manufactured:

Corner flap

This grating is particularly suitable for shelving with reduced-width shelves. Load absorption will be limited.

Flanged edge

This grating is suitable for various types of shelving and offers numerous advantages, the most important of which is its cost of manufacture. The butt joint between the two edges provides greater load absorption and safety, and the flanged edge locks the grating in place on the racks.

Flat edge

This grating offers good adherence and stability thanks to the contact between the lips on the underside and the racks.

Notched edge

The butt joint between the two edges provides greater load absorption and the flanged edge provides safety.

Press-welded grating is obtained by electrical welded transverse bars, which are usually square and twisted (but can be round and straight) into the bearing bars. The grating is produced with “flat” banding, and then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. For an optimised anti-slip surface, it is possible to produce serrated press-welded grating, with serration on the bearing bars only. It is typically manufactured from EN 10025 standard S235JR steel which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.
