Steel frame industrial builds across SEQ.

The most widely used system for industrial buildings in Australia — portal frame steel for warehouses, factories, distribution centres and sheds, offering large clear spans, fast site erection and cost-effective construction.

Structural steel portal frame erection

Clear spans without internal columns

Portal frame steel — a structural system using rigid frames of welded steel columns and rafters — provides the clear internal spans industrial occupiers need without internal columns interrupting the floor area.

Spans of 18 to 60 metres are routinely achievable, and heights from 5 metres to 18 metres to haunch are standard for industrial buildings.

Steel Frame Capabilities

Engineered, fabricated and erected

Portal Frame Design

Experienced structural steel engineers design frames to AS 4100:2020 and AS/NZS 1170, accounting for wind region, building classification, crane loads and special loading conditions — detailed for cost-effective fabrication and fast erection.

Fabrication & Supply

Structural steel fabricated by established Queensland and Australian fabricators using certified steel (AS/NZS 3678). Strong procurement relationships across SEQ ensure competitive pricing and programme reliability.

Roof & Wall Cladding

Colorbond steel or equivalent metal sheeting selected for the wind load zone and building height. Insulated cladding or sarking specified where thermal, acoustic or condensation control is required.

Crane Runway Beams

For factories and workshops needing overhead crane access, runway beams are integrated into the portal frame design, coordinated with crane suppliers for correct beam sizing, splice locations and end-stop detailing.

Mezzanine Structures

Steel mezzanine levels for storage, office or amenities, designed to appropriate live loads (typically 3.0–7.5 kPa) and integrated with the fire exit provisions of the main building.

Standards & Compliance

Material standards and compliance

All structural steel design is certified by RPEQ and delivered to the relevant Australian Standards.

AS 4100:2020 — Steel Structures (design and connection detailing)
AS/NZS 3678 & 3679 — Structural steel material standards
AS 4600 — Cold-Formed Steel (purlins, girts, secondary members)
AS/NZS 1554 — Structural steel welding
NCC compliance for class, fire separation and exit requirements

Frequently Asked Questions

Questions clients ask us

Erection of the frame for a 3,000–5,000 m² building typically takes 2–4 weeks once the fabricated steel arrives on site. Cladding follows over a further 3–6 weeks. Overall construction programmes for steel frame buildings of this scale are typically 16–24 weeks.

Yes. Extension is generally straightforward — new frames are bolted to the end frames of the existing building and cladding is extended to match. We can assess your existing building and design a structurally compatible extension.

Brisbane and the Gold Coast are classified as Wind Region B under AS/NZS 1170.2 — a moderate region that does not require cyclone-rated construction. Areas north of approximately Noosa Heads move into Wind Region C (cyclone). Our engineers design to the correct region for each project.

Yes. Overhead roller and sectional doors up to 8 m × 8 m or larger are routinely installed. The door head is typically supported by a portal frame header beam, and the structural design accommodates door opening widths within the column grid.
