Sun shadings
Sun-breaker gratings are an aesthetic element used to define spaces and surfaces, allowing light to illuminate the area naturally whilst creating an interplay of shapes. For added creativity in the visual appearance of a building, you can enhance the façade with press-locked facade boarding with aligned meshes.

Moderne Architektur
Manufactured mainly from press-locked gratings, sun-breaker boarding is also available as boarding with slanted struts, as half-iron boarding, in stainless steel and in aluminium.


Custom Manufature
GEI can manufacture made-to-measure pressed sun-breaker boarding to meet your requirements (layout, size, etc.). 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.
Mesh

Load tables
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.
