01Why South China
Australian specifications, South China fabrication capacity
Australian fabrication shops are busy and labour rates are high. For packages above 50 t, many builders split the work: local shops keep site-sensitive items and short-notice changes, and a Chinese fabricator supplies the bulk columns, rafters, trusses and floor steel. That split typically lowers the delivered steel cost by 20–35% compared with a full local package, depending on complexity and freight.
The risk buyers worry about is compliance, not price. We detail in Tekla to AS 4100 connection rules, run welders and procedures qualified to AS/NZS 1554.1, and issue an inspection and test plan against the AS/NZS 5131 construction category you specify. Every heat comes with an EN 10204 3.1 mill certificate, and third-party inspection at our yard is welcome before the container is sealed.
Mezzanine floors are a common entry order. Our patented truss floor deck needs no props, spans between secondary beams and arrives with the beams, stairs and handrails in the same shipment.

02Codes & compliance
Designing and fabricating to Australia requirements
Your engineer of record designs to Australian Standards. We detail, fabricate, test and document to the same standards so the steel passes the builder’s and certifier’s checks on arrival.
| Topic | Australia requirement | How we deliver |
|---|---|---|
| Design of steel structures | AS 4100 | Connections detailed to AS 4100 or to the designer’s connection schedule; calculations on request |
| Fabrication & erection | AS/NZS 5131, CC2 typical, CC3 for heavy or fatigue-loaded | ITP per construction category, dimensional records per piece |
| Welding | AS/NZS 1554.1 GP / SP | Qualified WPS/PQR, 100% UT on CJP welds, MT on fillets by sampling |
| Steel material | AS/NZS 3678, 3679.1; ACRS certification often specified | EN 10204 3.1 MTCs per heat; ACRS-certified mill route or independent re-testing agreed at tender |
| Loads | AS/NZS 1170.0 / .1 / .2 (wind), regions C and D cyclonic in the north | Design inputs taken from your drawings; we do not alter load assumptions |
| Corrosion protection | AS 4312 corrosivity, AS/NZS 2312.1 / .2 | Sa2.5 blast, zinc-rich systems or hot-dip galvanizing to AS/NZS 4680 |
| Bolting | AS/NZS 1252 high-strength bolt assemblies | Bolts sourced to AS/NZS 1252 or supplied by the erector, agreed per project |
Code references are typical for commercial and industrial work. The project specification always governs.
ACRS: many Australian specifications call for steel from ACRS-certified mills. We confirm at tender whether the plate and section mill route for your package holds ACRS certification. Where it does not, we propose an agreed alternative: EN 10204 3.1 certificates plus independent mechanical and chemical re-testing by a NATA-recognised or international laboratory, accepted in writing by your engineer before fabrication starts.
03Shipping routes
From Shenzhen and Guangzhou to Brisbane, Sydney, Melbourne and Fremantle
Australia is the longest of our regular Asia-Pacific routes and the most frequently served. Direct and one-stop services run weekly from Shekou, Yantian and Nansha.
| Port of loading | Port of discharge | Transit (days) | Typical mode |
|---|---|---|---|
| Shenzhen (Shekou / Yantian) | Brisbane | 12–13 | 40HQ / flat-rack |
| Shenzhen (Yantian) | Sydney (Port Botany) | 13–14 | 40HQ / flat-rack |
| Guangzhou (Nansha) | Melbourne | 14–15 | 40HQ / break-bulk |
| Shenzhen (Shekou) | Fremantle (Perth) | 14–16 | 40HQ / break-bulk |
| Guangzhou (Nansha) | Adelaide / Townsville | 15–18 | 40HQ, transshipment |
Transit times are typical port-to-port sailing times and vary with carrier, transshipment and season. Confirmed per booking in our quotation.
40HQ container
Members up to 11.8 m, typically 22–26 t per box for floor steel and rafters. Best for warehouses and mezzanines.
Flat-rack and break-bulk
Long trusses, columns to 24 m and heavy girders. Booked on multipurpose vessels into Melbourne and Fremantle.
Biosecurity-ready packing
Steel dunnage or ISPM 15 heat-treated timber, clean surfaces and declarations prepared for DAFF inspection.
Packing rules, 40HQ loading plans and break-bulk limits are covered in our 40HQ container steel loading guide and on the quality, NDT and shipping page.
04Building types
What we commonly supply for Australia projects
Most Australian enquiries are warehouses, mezzanine floors and build-to-print packages for local builders who keep erection in-house.
Build-to-print
Columns, transfer girders and trusses detailed and made to your AS 4100 drawings.
Commercial
Composite floor steel, box columns and transfer structures for mid-rise buildings.
Members and systems most often ordered
- Truss Floor Deck & Mezzanine: mezzanine floors in Melbourne, Sydney and Brisbane warehouses, no propping
- Purlins, Stairs & Platforms: stairs, platforms, handrails and purlins shipped with the frame
- H-Beams & Plate Girders: welded and tapered rafters, plate girders above rolled-section sizes
- Welded Box Columns & Beams: box and tubular columns for commercial frames
Typical steel consumption
Single-storey warehouses typically use 32–45 kg/m². A 2,000 m² mezzanine with truss deck, secondary beams and stairs is often 55–70 kg/m² including supports. Indicative FOB prices sit around USD 1,100–1,800/t depending on complexity, confirmed per quotation.
05Delivery model
Clear scope: what we deliver and where our responsibility ends
We supply fabricated, coated and documented steel. Erection stays with your Australian erector, who holds the local licences and site safety obligations.
FOB Shenzhen / Guangzhou
Steel delivered on board, export-cleared, with packing lists, loading plans and MTCs. You or your forwarder control freight and insurance.
CFR / CIF Melbourne / Sydney
Freight and marine insurance to the discharge port of your choice. Customs clearance, DAFF inspection and delivery to site stay with your broker.
Supervision & installation
Our erection supervisor can attend first lifts, bolt tensioning and survey checks. Erection crews are your local contractor; we do not undertake civil works.
- Shop drawings for your engineer’s approval in 5–10 working days
- ITP, weld maps, UT and DFT reports in the shipping dossier
- Erection marks matching the Tekla model and your erector’s sequence
- Spare bolts and touch-up paint shipped with the last container

07FAQ
Questions Australian buyers ask
Our engineers work with AS 4100 drawings every week and reply within 24 hours.
Other markets we ship to
Can you supply steel that meets AS 4100 and AS/NZS 5131?
Yes. We detail and fabricate to your AS 4100 design and issue an inspection and test plan against the AS/NZS 5131 construction category in the specification, usually CC2. Welding is to AS/NZS 1554.1 with 100% UT on complete-penetration welds.
Is your steel ACRS certified?
We confirm the mill route at tender. If the specified ACRS-certified source is not available for your sections, we propose EN 10204 3.1 certificates plus independent re-testing, accepted by your engineer before fabrication. We never substitute without written approval.
How long does shipping to Australia take?
Sailing from Shenzhen or Guangzhou takes 12–15 days to Brisbane, Sydney and Melbourne, and about 15 days to Fremantle. Add 25–40 days of fabrication after shop drawing approval.
Do you make mezzanine floors for Melbourne and Sydney warehouses?
Yes. We supply the complete mezzanine: columns, primary and secondary beams, truss floor deck, stairs and handrails, designed to your loads and shipped in 40HQ containers ready for bolting.
Will you install the steel in Australia?
No. Erection is done by your licensed local erector. We can send a supervisor for the first lifts, bolt tensioning and survey checks, and we provide erection drawings and sequences.
