Structural Design & Engineering
A portal steel frame design—including steel columns, beams, and bracing—works seamlessly with the enclosure system to create a fully sealed building capable of withstanding strong winds, heavy rain, and snow loads. All metal components are cut, welded, drilled, and painted in our factory before delivery.
Multi-Story Steel Frame Buildings
Our multi-story steel buildings—ranging from 3 to 20+ floors—offer a blend of strength, efficiency, and design flexibility. Ideal for urban, commercial, and industrial applications.
- High load-bearing capacity for large-scale use
- Rapid construction through prefabricated assembly
- Flexible design options to meet specific project requirements
Key Performance Traits
- High Strength-to-Weight Ratio: Steel's strength allows for lighter yet robust frameworks, reducing foundation loads while supporting multiple floors and heavy usage.
- Design Flexibility: Steel's adaptability enables open floor plans, large spans, and creative architectural features.
- Rapid Construction: Prefabricated steel components shorten build times by 20-40% compared to concrete structures.
- Durability & Resilience: With proper corrosion protection, steel resists environmental wear, fire, and seismic activity.
- Sustainability: Steel is 100% recyclable, and its lightweight nature reduces material waste.
Common Applications
- Commercial Buildings: Offices, shopping malls, and hotels
- Residential Complexes: Apartments or mixed-use buildings
- Institutional Facilities: Hospitals, schools, and government buildings
