The Benefits of Metal Web Joist Systems


What are Metal Web Joists?

Metal web or Posi joists are a combination of timber chords and pressed metal webs that connect together to form something called an ‘open-web’ joist.


When should you use open web joists?

When spans are greater than 5m, open web joists (aka Posi or metal web joists) suddenly become a very cost effective choice. Open web joists also have the added benefit of easier installation of electrical, plumbing, and ventilation services. They are also much better suited for future building modifications.

What are the advantages of using open web joists?

The metal web joist system provides so many benefits, including offering customers better value for money. Open web joists (Posi-joists) are composite timber and steel joists, forming an open and web formed design.

The open web designs mean that they’re lightweight, durable, strong, simple to install, and available in long lengths. The open web design means that using the joists offers a flexible solution for any future internal building layout modifications. In addition to this, they eliminate the time performing cutting and drilling exercises when installing services or incorporating modern ventilation and heat recycling systems.

Open web joists are engineered to be lightweight, dimensionally precise, and are supplied along with metalwork and timber materials, like metal connectors, temporary bracing, decking and additional timbers.

Where is best to use open web joists?

Aber Roof Truss’ open web joists allow for much longer clear spans, or for shallower depths than that which might be found on other engineered timber joists. They are absolutely perfect for floors or flat and mono-pitched roofs. 


Are open web joists eco-friendly?

Open web joists are an ‘eco-choice’ because of the fact that they cater for thicker insulation and mechanical heat recovery and ventilation systems, assisting with creating more energy-efficient buildings. Open web joists are suitable for all kinds of applications, including but not limited to domestic, industrial and commercial applications.


Are open web joists quick to install?

Yes, web joists are purposefully manufactured to size to provide fast and simple installation. The open web design also means that there is no more timely and untidy drilling or notching for electrical and plumbing services.

Save your time and money as different trade routes work simultaneously.

Remember that all buildings are different and require individual attention, some will require trusses, and others will require rafters.
