The fastest manufacturing leadtime for roof trusses & metal web joists in the UK

Floor Joists

Posi-Joist combines the lightness of timber with the strength of the Posi-Strut steel web allowing you to span far greater distances than would be possible with alternative timber products. Furthermore the exceptional strength characteristics result in much firmer floors with far less ‘bounce’ when compared to I-beams or alternative floor systems.

This gives you unequalled design freedom across a wide range of applications for both floor and roof in domestic, industrial and commercial applications. The Posi-Joist allows a variety of internal room layouts within an external shell due to its clear spanning capabilities.

Easy access for the installation and maintenance of the services in the floor zone is the clear advantage of the Posi-Joist system, and with the ever increasing need for MVHR (Mechanical Ventilation and Heat Recovery) systems, Posi-Joist provides a perfect and simple solution that just isn’t possible with alternative solid timber products.

Whilst an initial linear metre cost comparison with solid joist alternatives may suggest otherwise, Posi-Joist’s ability to span greater distances than its timber competitors, coupled with its open web design gives the contractor several important cost saving advantages. The installation of services and utilities is far simpler and quicker with Posi-Joists, reducing both labour costs and build-up time on site.

Joists are manufactured in a controlled offsite environment ensuring a quality product, and are delivered ‘made to measure’ allowing for speedy erection. What’s more, Posi-Joists will often eliminate the need for load-bearing intermediate walls, dramatically cutting overall building costs.
