Industrial floors and floorings
Press-welded gratings are used in industrial situations as their manufacture makes them highly resistant and reliable. Manufactured from S235JR steel, press-welded gratings are obtained by affixing twisted squares to bearer bars via electrofusion.
The benefits of press-welded gratings for industrial floors and floorings:
- Solidity and robustness of the works
- Available in standard mesh (e.g. 30x30) and security mesh versions (19x19 30x19, retains bearings of 20 mm).
- Manufacturing in execution possible.
- Easy assembly thanks to clamps.
Custom manufacture:
Our research department is available to handle your technical requirements and your intended layouts, and can advise you on issues up to and including the realisation of your orders.

Load tables
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.
