Our posi struts and posi trusses utilise an open metal web system enabling easy access, installation and concealment of plumbing, electrical and heating services.

The open web system ensures the structural integrity of our posi struts and posi trusses as modifications such as drilling, notching or cutting through timber joists to accommodate services is not required.

Posi strut open webs combine the flexibility of wood with the strength of steel, enabling large, clear spanning compared to conventional flooring trusses and joists.

Posi struts are up to 50% lighter than conventional joists resulting in easy handling and quick installation.

More effective load sharing compared to conventional floor joists.

Strongback bracing significantly dampens vibrations, increases floor stiffness and reduces bounce and movement in the flooring system.
