MiTek’s Posi-Strut enables efficient, reliable floor and roofing solutions, built on strength and quality
The construction industry must undergo constant evolution in a bid to meet the needs of increasingly demanding clients in relation to quality and cost-effectiveness. One such unique innovation is MiTek’s Posi-Joist, which combines the lightness of timber with the strength of the Posi-Strut steel web to produce a floor and roof system that allows you to span far greater distances than would be possible with some alternative timber products.
This gives architects unequalled design freedom across a wide range of applications for both flooring and roofing in domestic, industrial and commercial applications. Due to its clear-spanning capabilities, the Posi-Joist enables a variety of internal room layouts within an external shell.
Easy access for the installation and maintenance of services in the floor zone is the clear advantage of the Posi-Joist system, and with the ever-increasing need for mechanical ventilation and heat-recovery systems, Posi-Joist provides a perfect and simple solution that just isn’t possible with alternative solid timber products. Posi-Joist has been used in countless projects across the UK, US, Australia and New Zealand, with great success.
With the ability to span great distances and coupled with its open web design, MiTek’s Posi-Joist system affords contractors and architects unique advantages. The installation of services and utilities is far simpler and quicker with Posi-Joists, reducing both labour costs and build-up time on site.
Joists are manufactured in a controlled off-site environment ensuring a quality product and are delivered ‘made to measure’, allowing for speedy erection. What’s more, Posi-Joists often eliminate the need for load-bearing intermediate walls, all of which can cut overall building costs. MiTek is very confident that Posi-Joist will have a huge impact on the SA market once introduced.
Exceptional floor performance from a wide fixing surface makes flooring easy, controls shrinkage and, with precision engineering, those tiresome return visits and remedial work are reduced. More benefits such as the unique open web design provide an area in which plumbers, electricians and mechanical ventilation and heating contractors will find it easy and convenient to work. The job’s done far more quickly and the contractor makes worthwhile savings.
Design flexibility is inherent in the concept of the Posi-Joist. The depth, length and width can all be adjusted to produce an enormous number of different specifications, each with clearly defined performance criteria. In addition, end details of the Posi-Joist can be altered to offer a variety of support conditions. Posi-Joists can incorporate a trimmable end by integrating a solid timber block that can be engineered to provide up to 130 mm allowance at each end for trimming on-site.
Posi-Rafters are becoming increasingly popular in roof applications. As with Posi-Joist floor joists, they are designed and manufactured off-site and tailored to the requirements of each individual project. They arrive made to measure and accompanied by full layout drawings for the speed of erection. Posi-Rafters are suitable for both pitched roofs and flat roofs. They are stronger than solid timber rafters and so can span further and require less internal support.
Implementation of the Posi-Strut system is supported by PAMIR, industry-leading design software that combines layout, engineering, output and 3D tools into a single fully integrated application. Developed by MiTek’s European software-development team, this powerful and versatile alternative to traditional programmes ensures a much higher level of accuracy, as users can clearly see how different elements of a design interact.
