400mm (depth) but, Robert advises, consultation with a MiTek fabricator to get the right size for your job is recommended. The trusses come in lengths of up to 12 metres and can span 7.9 metres, meaning large open areas can be easily achieved. PosiTrusses can be fully customised and specifically engineered for any project and can accommodate a range of applications with special support conditions, eliminating the need for cutting on site. Created from kiln-dried timber, the PosiTrusses have consistent depth, which helps to provide a flat floor or ceiling every time MiTek’s 20/20 engineering software lays the structure out automatically and the trusses are then engineered with the specific support requirements for each application. ‘The trusses are then created in precision jigs for accuracy either straight or with a camber,’ Robert explains. Created from kiln-dried timber, PosiTrusses have consistent depth, which helps to provide a flat floor or ceiling every time. Kiln-drying also means shrinking problems commonly seen with the use of green hardwood joists are reduced or eliminated. Benefits of PosiTrusses • Plumbing, electrical, and heating and cooling systems can be run between chords and webs for easy access to services • Quick and easy to install, lightweight and easier to handle • Top chord support speeds up installation and reduces the need for fixings and brackets • Minimised construction time reduces construction costs • Greater spans can be achieved to create large open areas and increase design possibilities • Internal load-bearing walls to stumps and bearers can be reduced or eliminated • No need to straighten or pack on site • Reduced floor bounce and squeaking.
