Posi Joists are parallel chord trusses using stress-graded timber chords, plated together with patented, precision engineered metal webs, EP 1 985 774 A1 – the strongest available on the market.

Posi Joists offers unrivalled lightness, strength, and greater clear span ability.

Developed a decade ago, initially as a total floor solution, the Posi Joists system offers excellent versatility when designing floors, roofs, or walls. You can expect unrivalled performance from minimal material usage, with fewer webs required and up to 20% less timber used.

A great alternative to standard carcassing joists and I-Beams

With excellent spanning and load bearing capacity, Posi Joists can be positioned at any angle between 0 and 90 degrees, in a variety of situations.

Open web construction is ideal for accommodating services, and makes for simpler installation and reduced labour costs for the installation of pipe work, cabling and ductwork.

“the metalweb floor system with a rigid strongback reduces vibration and improves the overall performance of the floor”

High acoustic and fire performance standards benefit party floor construction within multi occupancy buildings.

Beams may be assembled into panel or cassette modules assisting you in attaining a sustainable and defect-free approach to construction.
