Offshore gratings
The Offshore gratings is especially for Oil Platforms been developed.
The benefits of offshore gratings
- Notched bearer bars for added stability
- Security : security mesh (19x19 19x40...) available that retains bearings of 20mm
- Quick to assemble with laps of up to 6 metres in length
- Durable, with bearer bars 5mm in thickness

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.
