Australia · Structural steel & modular
Structural steel fabricator for Australian projects
World Steel engineers, fabricates and delivers structural steel and modular buildings for Australia from one certified plant – AS/NZS 5131 CC3, welding to AS/NZS 1554.1, Australian-standard materials with full traceability. One supply chain, one quality system and one programme from shop drawings to the delivery that matches your erection sequence.

A specialist fabricator for the Australian market
Australian builders and engineers need more than a low price per tonne: they need steel that passes inspection the first time, arrives in the order it is erected and comes with the documents the certifier asks for. World Steel is organised around that – one fabricator responsible for detailing, material, fabrication, coating, inspection, packing and shipping, certified to AS/NZS 5131 for Construction Category 3.
Because every stage runs inside one quality system, you control quality and programme through one contact and one set of reports instead of coordinating mills, detailers, fabricators, coaters and forwarders separately.

IlustraçãoWS modular homes
Steel modular buildings, finished in the factory
WS modular homes are steel structures first: a galvanised steel module, 12.0 × 4.5 × 3.1 m, built on jigs in the same certified plant as our structural steel, then completed with envelope, bathroom pod, services and finishes before it ships.
For Australia each project is engineered and documented to the NCC and the site's wind, bushfire and corrosion conditions, so your Australian engineer and building certifier have what they need for approval. Your local builder prepares footings and connections while the modules are produced.

Regras de importação para estruturas metálicas
Australia: o que verificar ao importar estruturas metálicas fabricadas (HS 7308) ou edifícios pré-fabricados (HS 9406).
- The designer sets the AS/NZS 5131 Construction Category (CC1–CC4) – World Steel is certified for CC3; ACRS-certified material is supplied where the specification calls for it.
- Fabricated structural steel (HS 7308.90): MFN duty 5 %, 0 % under AANZFTA, CPTPP or RCEP with proof of origin for each shipment; GST 10 % on the value of the taxable importation.
- No anti-dumping measure on fabricated structural steel from Vietnam in the Anti-Dumping Commission's May 2026 status report – measures exist on some other steel products, so the HS code and goods description are checked for every order.
- Timber packaging and dunnage must meet Australian biosecurity import conditions (ISPM 15 treatment and marking); containers and flat racks are shipped clean.

Perguntas frequentes
Is World Steel certified to AS/NZS 5131?
Yes. World Steel is certified to AS/NZS 5131 for Construction Category CC3, which covers most building, industrial and infrastructure structures in Australia. The certificate is published on our certifications page.
Can you supply ACRS-certified steel?
Yes. Where the specification requires it, we procure material from ACRS-certified mills and keep full traceability from mill certificate to piece mark.
Which welding standard do you use for Australian projects?
AS/NZS 1554.1 (SP or GP category as specified), with welding quality management certified to ISO 3834-2.
Do you do the shop drawings and connection details?
Yes. We model in Tekla and issue approval, shop and erection drawings for review by your engineer; connection design follows the engineer of record's requirements.
How is quality controlled when the steel is fabricated in Vietnam?
Through an inspection and test plan agreed before fabrication, with hold and witness points your inspector can attend in person or by video, weekly progress reports and a pre-shipment inspection. All records go into the handover dossier.
Can you deliver in erection sequence?
Yes. Fabrication is released and packed by erection sequence or zone, and every bundle is marked so the site can unload in the order it builds.
What duty applies to structural steel from Vietnam?
Fabricated structural steel (HS 7308.90) enters duty-free under AANZFTA, CPTPP or RCEP with valid proof of origin; the MFN rate is 5 %. GST of 10 % applies. Use the landed cost calculator for an estimate – we confirm the position with each quotation.
Can WS modular homes be approved in Australia?
Each project is engineered and documented to the NCC and the site's conditions so your Australian engineer and building certifier can assess and approve it. Planning and building approval are obtained locally for each site.
Planning a steel structure in Australia?
Send drawings, a Tekla/IFC model or a specification – we reply with scope, fabrication programme and an itemised price delivered to your Australian port.
