Posi-Joist combines the lightness of timber with the strength of the Posi-Strut steel web to produce a floor and roof system allowing you to span far greater distances than would be possible with alternative timber products. 

"You simply can’t afford to ignore the advantages of the Posi-Joist system."

The benefits of Posi-Joist


The installation of services and utilities is far simpler and quicker with Posi-Joists, reducing both labour costs and build-up time on site.


Exceptional floor performance from a wide fixing surface makes flooring easy, controls shrinkage and with precision engineering it all reduces those tiresome return visits and remedial work.


Posi-Joist can adequately span for floors and for flat and pitched roofs, often allowing for increased joist centres when compared to alternative systems.

Material Savings

Tested by TRADA, included in ETA 07/0161 and accepted by NHBC, staggered Posi-Strut webbing reduces the material content of the joist providing economic and environmental savings.

You simply can’t afford to ignore the advantages of the Posi-Joist system.

Posi-Joists have many advantages over timber engineered joists. We manufacture all our joists to strict tolerances and specific designs to give the most economical but structurally sound floor. 

We provide full on site detailed drawings to ensure the fitting time is kept to a minimum.
