One of the major challenges in construction is working in a limited space beneath the floor, or in the roof, to allow for various services and pipework. MiTek’s Posi-Joists system is the ideal solution.
Posi-Joists and Posi-Rafters are revolutionary in the construction industry, combining the versatility of timber with the strength of steel webs to produce a floor and roof system with numerous benefits. The main advantage is the service void created by the open web design, allowing for services and pipework to be easily installed. The steel webs also create a massively strong joist, capable of clear spanning far greater distances than alternative systems. Posi-Joists are lightweight and easy to handle; they are delivered to site, made to measure allowing for speedy installation, and being factory-manufactured offsite, you can be sure of a quality product.
Posi-Joist technology is a metal web joist system that can be used for floor and roof structures. Posi-Joists are designed and manufactured to suit each project and can be specified in a wide range of widths and depths to satisfy individual project requirements. The clear span capabilities can eliminate the need for load-bearing walls or steel beams, offering increased design freedom.
The Posi-Joists and Posi-Rafters system combines the lightness of timber with the strength of the Posi-Strut steel web for strong floor and roof systems. Posi-Joist enables designers to span far greater distances than would be possible with alternative timber products. The depth, length and width can all be adjusted to produce countless different specifications, each with clearly-defined performance criteria.
“The unequalled design freedom is what continues to set this system apart in the industry. From the ability to design creative floors and roofs in domestic, commercial and industrial applications, to the variety of internal room layouts that a clear span offers – there are many benefits to using Posi-Joist,” says Hennie Viljoen, marketing manager of MiTek.
Posi-Joist also allows easy access for the installation and maintenance of services in the floor zone. With the ever-increasing need for Mechanical Ventilation and Heat Recovery (MVHR) systems, this solution can streamline the construction process. Posi-Joist has been used in countless projects across the UK, Australia, and New Zealand with great success.
“Posi-Joists and Posi-Rafters are revolutionary in the construction industry, combining the versatility of timber with the strength of steel webs to produce a floor and roof system with numerous benefits.”
While an initial linear metre cost comparison with solid joist alternatives may suggest otherwise, Viljoen says that Posi-Joist’s ability to span greater distances than its timber competitors, coupled with its open web design to accommodate services, gives contractors several important cost saving advantages.
“The span capabilities mean that Posi-Joist can often allow for increased joist centres when compared to alternative systems, reducing material content. The installation of services and utilities is far simpler and quicker with Posi-Joists, reducing both labour costs and build-up time on site,” says Viljoen. MiTek is very confident that Posi-Joist will have a huge impact on the South African market once introduced.
Joists are manufactured in a controlled offsite environment ensuring a quality product that is delivered ‘made to measure’, allowing for speedy erection.
So far, we have received great interest for Posi-Strut systems in SA, and we will most likely introduce it to the SA market during the 1st half 2021.
“Exceptional floor performance from a wide fixing surface makes flooring easy and controls shrinkage. Precision engineering reduces those tiresome return visits and remedial work so that the job is done far more quickly, and the contractor achieves worthwhile savings,” concludes Viljoen.
