DWB POSI-JOISTS You simply can't afford to ignore the advantages of the Posi-Joist™ system designed and fabricated by DWB.

To start with, because Posi-Joist™ combines the lightness of timber with the strength of the Posi-Strut™ steel web, you can span far greater distances than would be possible with alternative timber products.

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.

Exceptional floor performance from a minimum 72mm wide fixing surface makes flooring easy, controls shrinkage, and with precision engineering it all reduces those tiresome return visits and remedial work.

More benefits such as the unique open web design provide an area in which Plumbers and Electricians will find it easy and convenient to work. The job's done far more quickly and the contractor makes worthwhile savings.

Even on long spans, no herring-bone strutting is necessary with the Posi-Joist system. If the span exceeds 4m, a strong-back is installed at mid-span.

The Posi-Joist™ does not just joist floors it can adequately span for flat and pitched roofs. Its span capability and timber flanges make it the more desirable alternative to all steel systems.

Posi-Joist™ standard details are published along with the DWB/Mitek World Of Floor Technology, available in the download area of this site.
