Product Q&A

Q:What is AS 4100 and why is it important for this rafter?

AS 4100 is Australia's core standard for structural steel, referenced by the National Construction Code (NCC). All our rafters follow AS 4100 Limit States Design (ULS & SLS), which facilitates approval in all Australian states and territories.

Q:Why select box section rafter instead of UB/UC open sections?

Closed box sections feature outstanding torsional rigidity, ideal for buildings with overhead cranes and eccentric dynamic loads. It delivers stable biaxial bending performance to reduce lateral bracing requirements. Sealed inner surfaces also lower long-term corrosion risks and maintenance costs.

Q:Can the rafter be customized to match my workshop demands?

Yes. We tailor depth, plate thickness, span, steel grade and connection details according to your building layout, crane tonnage and load conditions. We supply AS 4100 compliant design reports and complete shop drawings for local approval.
