Press-welded gratings for balustrades and fencing
Press-welded gratings for fencing or solid balustrades are manufactured from galvanised steel, with a powder-coated finish to RAL standard if required. They are quick to assemble and offer good resistance. Whether in stadiums, factories, airports or by private individuals, press-welded gratings for fencing are used in a variety of different contexts.

Custom manufacture
Depending on the layout and dimensions you require, several different meshes and cross-sections can be manufactured. For use as a balustrade, the NF P01-012 (paragraph 2.3.2) standard imposes a maximum horizontal gap in the mesh of 50mm). (Please give details when ordering).
We can also manufacture posts made from square or flat tubing sealed directly or with prepierced connectors exclusively for fencing (No swing bag test has been carried out.).

Assembly
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.
Step 1 :
