When it comes to floor and flat roof systems, selecting the right joist can be challenging. With decades of experience in engineered timber, Merronbrook Ltd has made the decision simple—we recommend the open metal web joist system, specifically easi-joist® by Wolf Systems.
As modern buildings become increasingly service-heavy, the need to accommodate plumbing, electrics, and HVAC systems within the floor zone has never been greater. Traditional joists often require cutting, notching, or drilling on site—adding time, labour, and the risk of weakening structural performance.
The easi-joist® system eliminates this problem entirely. With pre-formed service voids, trades can route cables and pipework through the joist zone quickly and without compromise.
Key Benefits of the easi-joist® System
At our Hampshire manufacturing facility, we use Wolf Systems’ advanced software and CNC technology to produce precision-engineered floor joists to exact specification. Our easi-joist® range is constructed using kiln-dried, stress-graded timber chords connected with precision-engineered metal webs—offering unmatched reliability and performance.
Available Sizes
Whether you're designing a residential home, a commercial building, or a multi-unit development, our open metal web floor joists offer a future-ready solution. They integrate seamlessly with our timber frame systems and can even be used alongside our attic trusses for combined roof and floor builds.
