Metal Press Web Posi Joists

We design, engineer and manufacture Posi floor joists and floor / roof cassettes for all building projects, from small domestic builds through to residential developments.

Metal Press Web Posi Joists

The design of our Posi joist combines the lightness of timber with the strength of the Posi-Strut steel web to produce a floor and roof system (Posi Rafters), which allows you to span a far greater distance than would be possible with an alternative timber product.

The benefit of using the Posi joist within your build is that it provides you with easy access for the installation and maintenance of services in the floor zone, as this would not be possible with a solid timber product. 

If you are unsure of whether Posi Joists would fit within your proposed design, please use the MiTek span calculator below:

We offer a complete joist package, which consists of the following items:

  • Metal press web joists
  • Rim boards & trimmers
  • 22mm chipboard flooring & adhesive
  • All metalwork

Fabrication & Transport

  • Manufactured to meet your delivery schedule
  • Packs are labelled to ease the installation process
  • Drawings/layouts to be issued with each delivery
  • Packs are transported so they can be easily offloaded by crane

Floor & Roof Cassettes

Metal press web Posi joist cassettes are becoming a popular choice as they can improve on site safety along with reducing construction time. All cassettes are manufactured through a controlled environment, ensuring consistent quality every time.

Each specifically designed cassette is manufactured with lifting straps attached, which ensures safe lifting for both transportation and site installation.

Should you require something more bespoke, we can offer a tailored solution to meet your specific needs.
