Metal web joists can span greater distances than solid or fabricated timber alternatives and, given that they provide an economic alternative to steel or concrete beams, considerable savings can be made in the use of raw materials. The open web design makes for simpler and faster installation on site, thereby reducing labour costs. The higher structural integrity of the beam reduces the need for additional intermediate supports, further reducing design and overall construction costs.
Howarth Timber Engineered Solutions provide a comprehensive design service where we, in collaboration with our clients and their design teams, will evaluate the feasibility and subsequently develop an appropriate design solution. In recognition of the considerable time savings that can be achieved with off-site fabrication and assembly, we can also supply components ready assembled in cassette form.
Particularly useful for larger projects or developments, all POSI beam products are location-coded and bundled specifically for plot or project delivery. We can provide details and guidance on load weights and dimensions for organising and managing site lifting and installation.
- Wide range of sizes. The depth, length and specification can all be adjusted to produce joists with specific performance criteria that can span greater distances than solid timber joists.
- Design flexibility. Metal web joists can eliminate the need for loadbearing intermediate walls, giving the designer greater freedom and flexibility.
- Dimensional stability. The use of smaller timber sections together with the metal webs means that there is less shrinkage and a reduced risk of squeaky floors
- Improved sound performance. Metal web joists when used with a rigid ‘Strongback’ reduce vibration of a floor.
- Lightweight. The open web structure means they are lighter to handle than solid timber joists.
- Reduced costs. Increased spans, simpler installation of utilities, flexibility in design and faster erection can result insignificantly reduced building costs.
