GEI can manufacture made-to-measure full gratings to meet your requirements (layout, size, etc.). Gratings can also be powder-coated if required.
Our research department is available to handle your technical requirements, and can advise you on issues up to and including the realisation of your orders.
The mesh spacing is defined in accordance with the standards and loads that must be respected:
- BB thickness of 2, 3, 4 and 5 mm
- The BB spacing is typically a multiple of 11.
- The IB spacing is typically a multiple of 11.1.

GEI press-locked grating is characterized by transverse, cross bars inserted under high pressure into pre-existing notches in the bearing bars. This grating is produced in “flat” or “T”-shaped sections, welded into place and then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. For situations with an increased risk of slipping, anti-slip grating can be produced, where the upper surface of the bearing bars and/or the transverse bars can be given anti-slip serrations. GEI press-locked grating is typically manufactured from EN 10025 standard S235JR steel, which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.
