The MiTek Posi-STRUT™ system is a light, economical method of providing large clear spans in rafter, purlin and floor joist applications. Frames and supports can be spaced further apart to facilitate open spaces below.
The heart of the Posi-STRUT truss is the Posi-STRUT web. This is a folded metal web with nail plate teeth at both ends. The metal web is pressed onto timber chords to form a parallel chord truss.
We recommend you read the Posi-STRUT manual which contains the necessary design selection, fabrication and construction information sufficient to detail most projects. MiTek New Zealand Limited provides a design service for applications outside this manual.
