Steel Structure Building
Portal Frame / Industrial Warehouse
Custom steel portal frame buildings for factories, warehouses & logistics centers. Section steel main frame, 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 in 25–35 working days. 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.
