Frequently Asked Questions About Our Products
What do steel floor joists actually do?
Steel floor joists support the floor structure by carrying loads across spans and transferring weight to walls and beams. They help create a stronger floor and reduce movement, giving a more solid feel underfoot.
What are POSI joists, and why do builders use them?
POSI joists are engineered steel joists with an open-web design that provides strength while leaving space for services. On site, many builders call these POSIs, as it’s a common Australian term.
What does Posi-Strut mean in floor framing?
A posi strut floor system uses steel joists designed for long spans and easy service runs. It’s a practical choice for double-storey homes because it reduces the need for cutting and drilling during installation.
Do you supply strutting and stiffening parts as well?
Yes. Where the design requires it, we supply steel strut components and connection hardware to help keep joists stable and performing correctly under load.
Can you supply steel floor joists for houses and townhouses?
Yes. We supply residential steel floor joist packages to suit single homes, townhouse developments, and renovations where strong floor support is required.
Do you provide joists for commercial floors?
Yes. We supply commercial steel floor joist systems for offices, shop builds, and other commercial spaces where consistent load performance is required.
What about heavier-duty industrial floors?
Yes. We can provide industrial steel floor joist solutions for workshops and industrial buildings, tailored to suit higher load requirements and site conditions.
Are your joists engineered and compliant?
Yes. Our joist packages can include certification and documentation, prepared to meet Australian compliance and installation requirements.
How do I get pricing for floor joists?
Send through your plans, and we’ll review spans, layout, support points, and floor loads. We then provide pricing, lead times, and delivery or install options.
Will the joists arrive labelled for installation?
Yes. Joists are delivered with clear labelling and supporting information, making it easier for installers to set out and frame the floor quickly.
