Posi-Strut webs are increasingly being incorporated into roof structures to take advantage of the many benefits on offer.
Posi-Rafters are parallel chord trusses, plated together with Posi-Strut metal webs. As with Posi-Joist floor joists they are designed and manufactured offsite and tailored to the requirements of each individual project. They arrive made to measure and accompanied by full layout drawings for speed of erection.
Posi-Rafters are suitable for both pitched roofs and flat roofs. They are stronger than solid timber rafters and so can span further and require less internal support.
A wide range of depths and end details provide great flexibility in their application, and the need for expensive hangers and metalwork can be eliminated through clever detailing and connections.
The open web construction allows for services and utilities to be easily routed through the rafters with no need for cutting or drilling or battening out.
