Metal Web Joists

Engineered Open Metal Web Joists We offer an in-house open web joist design which can be supplied as part of a SIP package or on their own.  Our engineered metal web SpaceJoist system offers a number of benefits including:

  • Open Web System. Light but strong with open webs means our joists can span further with less costly notching and drilling.
  • Long Spans.  Longer spans than comparable solid timber meaning more open areas and potentially less internal load-bearing walls, saving costs.
  • Quieter.  Reduced deflection and vibration lead to outstanding acoustic performance.
  • Easier Service Installation.  Open web joists lead to less notching and drilling of services and can accommodate larger services like MVHR.
  • Lightweight.  Our metal web joists are easy to manhandle leading to reduced crane costs and easier manoeuvrability.
  • Cost Savings.  Less drilling, reduced cranage, the potential for less loadbearing walls mean metal web joists save you money.


All of our engineered SpaceJoists are manufactured and designed in house to our CE marking, meaning our metal web joists are fully approved by Building Control and Warranty providers.
