| 1 | High strength and light weight Steel structures offer superior strength-to-weight ratios. Compared to concrete structures, steel beams and columns require smaller cross-sectional areas, increasing usable space. Typically, steel columns occupy about 3% of building area versus 7-9% for concrete. |
| 2 | Rapid construction Factory-prefabricated components enable fast on-site assembly through welding or bolting. Steel structures can serve as their own construction load-bearing systems, eliminating formwork needs and accelerating construction by approximately 1.5x compared to concrete. |
| 3 | Efficient utility routing The structural design allows convenient pipe and conduit installation within truss spaces or hollow members, simplifying maintenance and reducing required floor heights compared to concrete alternatives. |
| 4 | Environmentally friendly construction Steel construction minimizes use of sand, stone, and cement, reducing dust, waste accumulation, and noise pollution typically associated with traditional building methods. |
| 5 | Sustainable solution The steel construction industry represents an environmentally responsible approach with efficient resource utilization and minimal ecological impact. |
All structural components, panels, bolts, and accessories are packed in standard ocean transportation containers, typically loaded into 40'HQ containers.
