Engineered Open Web Joists

In our constant efforts to offer customers the latest in construction innovation we recently branched into the design and manufacture of Open Web Joists, an alternative to conventional timber joists or concrete floor slabs.

Combining the lightness of timber with the strength of steel, Steel Webbed Joists efficient, sturdy and structurally sound alternative to current floor and roofing systems. The distinctive design can be used in floors, roofs and can even be adapted into attic trusses, to achieve larger spans, easy routing of services and massive savings made on labour, time and costs.

Floor and roof sections (cassettes) can be delivered to site and craned into position to save build time.

Many features and benefits

Features & Benefits

Long spans: Longer spans are achievable in comparison to solid timber. This may eliminate the need for intermediate load bearing internal walls, thus reducing a building’s overall cost.

Design flexibility: Open Web Joist can be designed top hung to eliminate the rim board, decreasing the risk of timber shrinkage to improve air tightness.

Less timber and fewer webs: Tests show that the NEW Open Web Joist system requires less construction material - saving cost.

Sound performance: Open Web Joists deliver outstanding acoustic performance to comfortably pass stringent regulations, without additional insulation, plasterboard or resilient bars.

Easy to handle: Now even lighter, the lightweight construction makes Open Web Joists easy to individually manhandle on site without the need for crane hire. Alternatively, floor and roof sections (cassettes) can be delivered to site and craned into position to save build time.

Wide nailing surface: Fixing of floor and ceiling materials is simpler and quicker due to the minimum chord width of 72mm.

Engineered: Open Web Joists are manufactured offsite ensuring consistent quality and reliability.

Open web design: Fast and simple installation of services, without the need for drilling or notching. Joists can accommodate large services such as Mechanical Heat Recovery Systems.

Attic bottom chords: SpaceJoists can be incorporated into attic truss bottom chords to achieve greater spans, deeper insulation and provide a service void.
