Steel Structure Building
Portal Frame / Industrial Warehouse
Custom steel portal frame buildings for factories, warehouses & logistics. Z/C purlins, AS/NZS, BS & GB standards. CE certified.
Product Overview
Our steel structure buildings are the backbone of modern industrial construction. Using portal frame or truss systems, we deliver clear-span spaces up to 60m without internal columns — maximizing usable floor area for manufacturing, storage, and logistics operations.
Each building is engineered to your local design codes (AS/NZS 1170, BS 5950, EN 1993, or GB 50017) and comes with full calculation reports, fabrication drawings, and erection manuals. Our 5 production lines output 5,000 tons per month, ensuring on-time delivery for projects of any scale.
A typical 3,000 sqm warehouse structure ships from our factory with a lead time of 15–30 days depending on project size. We provide optional on-site supervision and can recommend local erection contractors through our network. Every bolt, plate, and member is labeled and match-marked for rapid assembly — crews typically erect 500–800 sqm per day with a 5-person team.

Frequently Asked Questions
Common questions about steel structure building
How much does a steel structure building cost?
Steel structure building costs range from $25 to $110 per square meter depending on size, design complexity, and local code requirements.
How long does it take to build a steel structure?
Factory production lead time is 15–30 days depending on project size, from design approval and deposit to shipment. On-site erection takes 4–8 weeks depending on building size and is separate from factory lead time. Sea freight depends on the destination port.
What certifications do you have?
Our factory is CE (EN 1090), TÜV and ISO 9001 certified. Welding procedures follow AWS D1.1 / EN 1090-2. Mill test certificates (MTC) are provided for raw steel.
Can you design to my local building code?
Yes. We design to IBC, Eurocode, AS/NZS, and most national building codes. Full structural calculations included.
Do you provide installation overseas?
We provide erection manuals, remote video guidance, and can dispatch supervisors for on-site installation support.
