Purlins and girts are horizontal support beams that provide essential strength to the roof and wall panels. These components, shaped like Zs with reinforced edges, ensure stability and load distribution.

Eave struts are angled beams connecting the roof and walls at the building corners. Featuring an asymmetrical C-shape, these beams follow the roof slope on the top side, while the bottom is broader for enhanced strength, complete with reinforcing lips for extra durability.

Bracings are diagonal rods or cables strategically placed across the roof and wall frames to ensure structural integrity. They provide essential resistance against wind forces, cranes, and seismic activity, helping maintain stability during dynamic conditions.

These lightweight yet strong beams support roof or floor decks, transferring weight efficiently to the mainframes. Open steel web joists offer a cost-effective and reliable solution for building roofs and floors while maximising performance and minimising material use.
