Timber Frame Floor Systems

Metal / Open web joists are typically used in the construction of intermediate floors (and roofs) in either domestic or non-domestic buildings. They are manufactured by combining structural timber for the top and bottom flange with the strength of v-shaped steel webs, making the product very lightweight, strong and versatile.

Deeside design and manufacture metal web joists and are proud to partner with Mitek (Pamir) offering the Posi-Joist system. For more information, please view or download our brochure.

One of the key benefits of metal web joists is the ‘open’ web which enables quick and simple installation of the mechanical, plumbing and electrical services. In addition, by combining the lightness of timber with the strength of the Posi-Strut Steel Web, it creates a joist which can span far greater distances than would be possible with alternative timber products.

• Engineered Value – Posi-Joist’s ability to span greater distances than its timber competitors, coupled with its open web design offers a number of important cost saving advantages:
  • The span capabilities allows for increased joist centres, 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.
  • Joists are manufactured in a controlled offsite environment ensuring a quality product, and are delivered ‘made to measure’ allowing for speedy erection.
  • Posi-Joists can be utilised as part of a wider structural engineering appraisal in order to reduce (or eliminate) the need for load-bearing intermediate walls, all of which can dramatically cut overall building costs.
• Acoustic Performance – exceptional sound performance to comply with UK building regulations.
• Fire Performance – fully compliant with BS and EN fire resistance standards for both intermediate and separating floors.

Posi-Joists are designed for manufacture and assembly using Mitek’s PAMIR software, during this process an accurate 3D drawing is created which can be shared with sun contractors and customers to ensure all aspects of the project are correct. Posi stuts are produced by Mitek at their metalwork factory in Dudley and delivered to Deeside where each joist is the fabricated using our AV Birch Uni-Roll 750.

Deeside are responsible for the design and manufacture of our metal web floor systems. Our combined knowledge and experience in partnership with Mitek’s technical and software support put us at the forefront to deliver a wide range of solutions. 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 give a variety of support conditions.
