A. C. Roof Trusses Ltd was one of the first in the UK to introduce the Mitek Posi-Joist system. Posi-Joists combine 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 a 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.  

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.

The unique open web design makes installation of services and utilities far simpler and quicker resulting in a reduction in both labour costs and build time on site.
