Posi-Joists
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. Below is more information on the system, and when and
how you can use it.
What is a POSI-JOIST?
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.
Posi-Joists are only manufactured by
licensed MiTek Manufacturers and are produced in factory-controlled
conditions ensuring a quality product every time. Manufacturers use the
very latest design and engineering software and create detailed design
drawings with powerful 3D visualisation tools to assist with
installation. Posi-Joists are delivered to site made to measure and can
incorporate a variety of end details to speed up erection and eliminate
costly metalwork.
When to use a POSI-JOIST?
Posi-Joist
can be suitable for use in all buildings, residential, industrial or
commercial, and for both floor and roof applications.
Used in
floor applications, it can span further than alternative systems and
products. Posi-Joists are dimensionally stable; not suffering from
shrinkage or distortion that can lead to squeaky floors. Additionally,
the wide flange gives a wide and stable fixing area for laying the floor
and ceiling deck.
In roof applications,
Posi-Joists are incredibly versatile and can be used for flat, low and
steep pitched roofs. Their strength means they can span greater
distances than other systems and often eliminate the need for beams and
purlins. A wide variety of end details allows for versatility and ease
of installation on site. Attic roof trusses can incorporate a Posi-Joist
bottom chord, to achieve greater spans, as well as all the benefits of
the open service zone.
Benefits of POSI-JOIST
The
main benefit of the Posi-Joist system is the open web construction,
which provides easy access for the installation and maintenance of
services within the floor zone. Pipework, ducting, cabling and other
services can be easily and quickly installed with no need for cutting or
drilling and with no risk of damaging or limiting the performance of
the joist. With the ever-increasing demand for MVHR (Mechanical
Ventilation and Heat Recovery) systems, Posi-Joist provides the perfect
simple solution to accommodate the large and extensive ductwork
required.
The strength of the system means that joists can clear
span substantially further than other products, requiring fewer internal
supports. Along with the time savings offered during service
installation by the service void, site labour costs can be significantly
reduced.
Joists are individually
designed, and factory manufactured to measure for each project, and
their lightweight construction means they are quick to erect and can be
handled with no need for crane hire.
