Posi Rafter / Flat Roofs

Posi Rafters are parallel chord trusses, plated together with Mitek Posi- Strut webs and manufactured using strength graded TR26 timber.

The Posi-rafter system offers unique design versatility in a wide range of applications, including flat and pitched roofs. Posi-rafters are made offsite and tailored to requirements of each individual project. They can span further, requiring less internal support than traditional rafters. The open web design allows easy installation of services.
