Prefabricated Construction
We customize your multi-storey prefab buildings in steel construction
Looking for a safe, modern, and cost-effective multi-storey solution? Our multi-storey steel buildings use military-grade steel with seismic resistance up to magnitude 8 and wind resistance up to Level 15. A 6-storey structure can be completed in just 90 days. Compared to traditional concrete buildings, this solution reduces construction costs by 30% and increases usable space by up to 15%—a true benchmark for the next generation of efficient buildings.
