Common Uses and Sectors: Structural Steel Beams
Structural steel beams are ubiquitous in construction and can be used anywhere a strong horizontal support is needed. In home building and renovations, steel beams often serve as floor bearers, strutting beams, verandah supports, lintels above wide openings, or even roof rafters. They allow for open-plan layouts and support additional storeys in residential projects. In larger commercial and industrial builds, structural beams form the skeletal frameworks of warehouses, offices, and factories and support infrastructure like bridges and mezzanines.
A wide range of industries rely on structural steel beams. Edcon Steel has supplied beams for residential housing developments, retail and education buildings, and heavy industries like mining and defence projects. Builders and engineers appreciate the high strength-to-weight ratio of steel beams, which ensures safety and stability in multi-storey constructions and long-span structures. Structural beams provide the robust support needed to get the job done, from home DIY projects to large infrastructure works.
For more information, read our blog about Builders Steel. Additionally, the OneSteel guide for builders and owner-builders provides support in the design, sizing, and applications of structural steel beams for domestic and house building.

Read MoreFrequently Asked Questions
What is a structural steel beam?
A structural steel beam is a load-bearing steel section (often called a Universal Beam (UB), I-beam, H-beam or RSJ) used to support horizontal spans, floors, or roofs.
What steel grade do your beams use?
Our structural beams are manufactured from hot-rolled mild steel complying with AS/NZS 3679.1 (Grade 300+) or equivalent, ensuring structural quality and compliance.
What sizes and lengths are available?
Typical section depths range from around 150 mm up to 610 mm for standard UBs, and standard lengths are between 9.0 m to 20.0 m. Custom lengths and cuts are available.
Can the beams be cut to size and delivered / collected?
Yes — beams can be custom-cut to the millimetre (minimum cut length ~15 mm). Delivery across the country or click & collect is available via our branches or freight partners.
What finishes or coatings are offered?
Default finish is mill (raw) finish. Optional coatings (on request) include primed (painted) finish or hot-dip galvanised for enhanced corrosion protection.
What are common uses for these beams?
They are used in residential, commercial and industrial construction: for floor bearers, verandah supports, lintels, roof rafters, open-plan post and beam layouts, commercial frames, warehouse spans and infrastructure.
Are the beams Australian-made and traceable?
Where possible we stock Australian-made steel and provide full mill certification/documentation on request to ensure traceability and compliance.
What fabrication services are available?
In addition to cutting, we provide services like drilling, welding, adding plates or cleats, enabling you to receive beams ready for installation.
What should I consider when choosing the right beam?
Key considerations include span, load, environmental exposure, beam profile (UB, PFC, etc), finish/coating required, budget, and whether any fabrication is needed. Consult with a structural engineer if unsure.
