If you are looking for a more economical and easier way to construct long span floor rafters or purlin systems then MiTek’s Posi-STRUT® open web truss system is for you.

Posi-TRUSS® are open web trusses based on a unique "V" shaped steel web with integral teeth, which, when used with timber chords, forms long, strong, parallel chord trusses. This means you enjoy the strength of steel, together with the easy fixing and handling of timber.

Posi-TRUSS® unique open web design means you can duct services like plumbing, electrical and air conditioning between the top and bottom chords, with no need for drilling, notching or construction of extensive bulkheads. This feature alone greatly reduces construction time and costs, and allows you to get your project to completion much faster.

And, the time and cost savings don’t end there.

Because Posi-TRUSS® are 50% lighter than conventional solid timber joists, handling is much faster and easier. They are also manufactured to meet the requirements of your job, so there is no on-site trimming required.

As Posi-TRUSS® use 70mm or 90mm chords, they do not require temporary bracing and floor and ceiling materials can be joined at each truss without doubling up floor joists or using packers.

Posi-TRUSS® also allows you a greater degree of design flexibility. They are strong enough to allow clear spans of more than seven metres, so you can achieve large internal spaces.

Where exact spans cannot be determined prior to manufacture, Posi-JOIST® or Posi-PLUS® with trimmable end panels, can give you all the benefits of Posi-TRUSS® with the flexibility to trim quickly and easily on site to the exact length required.

Posi-TRUSS®, Posi-JOIST® and Posi-PLUS® trusses performance and economy have been proven on many projects around Australia, from houses to multi-residential and commercial properties, so you can be sure that they will provide the best solution for your long span floor.
