Key Advantages
- Lightweight yet strong: Steel structure weighs less than traditional materials while offering superior strength and toughness.
- Excellent seismic performance: Uniform material properties provide outstanding earthquake resistance.
- Fast construction: Factory prefabrication and on-site assembly significantly reduce construction time and costs compared to concrete structures.
- Eco-friendly solution: Environmentally conscious construction with fully recyclable materials reduces resource waste.
