Using a ground-breaking system that combines open web steel and timber to produce super-light beams with excellent structural integrity, Space-joists are the perfect choice for all floor applications. Unlike traditional steel or all-timber floor joists, metal web joists utilise the strengths of both materials by bringing together the strength of metal with the lightness of wood.  This results in a system which is lighter than an all-steel equivalent, has a cleverly built-in access for services, and overall performs much better than traditional all-timber joists.

The open web joists themselves are manufactured in our factory using the latest design software to create made-to-measure products to your exact specifications.  Your joists will then be delivered on-site and ready to install; reducing wastage, removing the need for alterations and saving on fitting time.


Why choose space joists?

• Longer spans are achievable in comparison to solid timber
• Manufactured to size eliminates site alterations saving time on site
• outstanding acoustic and sound performance 

• Lightweight construction makes Space Joists easy to handle

• Space Joist systems require less construction material, saving cost

• Fast and simple installation of services, without the need for drilling


One of the biggest advantages of using a SpaceJoist system, is the ability to suit the floor joists to your needs. Take a look below at the different details available when working with SpaceJoists.
