Do you know why steel buildings will eventually replace traditional brick buildings?
Steel Structure Buildings are Core Benefits of steel buildings
steel buildings are High Strength and Lightweight
Steel is 5-10 times stronger than concrete and only 1/5th as dense as brick and concrete. For example, a steel roof frame weighs only 1/4-1/3th as much as a concrete one for the same span of a roof structure. This lightweight feature significantly reduces the pressure on foundations, which makes it especially suited for steel buildings in soft soil areas or seismic zones.
Steel Buildings Offer Superior Seismic and Durability Performance
Steel's ductility and modulus of elasticity allow it to effectively absorb seismic energy, and the seismic performance of steel buildings is more than 50% higher than that of brick and concrete structures. The design of steel encased in dense concrete also improves corrosion resistance and reduces maintenance costs by 60%.
Steel structure buildings are efficient and environmentally friendly.
Factory prefabrication rate can reach 90%, and on-site assembly period is shortened by 40%, such as Wuhan Vulcan Mountain Hospital built in 10 days thanks to this. The steel recycling rate is over 95%, which reduces construction waste emission by 80% and meets green building standards.
Steel buildings are Space Utilization and Design Flexibility
Small cross-section of steel members increases the opening area by 50% under the condition of the same beam height, and it can be customized with shaped structure (e.g. arched roof, overhanging design). The non-load-bearing characteristics of the wall support free division, adapting to the complex needs of commercial complexes and so on.
Distinguishing features of steel buildings
Material Performance Dimension
Isotropic homogeneous body, accurate force analysis, higher reliability than brick-concrete structure
High temperature resistance up to 250°C (short-term), fire-resistant coatings are needed to make up for the fire-resistant short board.
Industrialized production mode
BIM technology realizes millimeter-level error control of components
Standardized modules reduce labor dependence and construction is less affected by seasons
Expansion of application fields of steel structure buildings
Traditional Areas of Strength
Ultra-high-rise Buildings: Financial Center (599m) uses steel frames for its core
Large-Span Structures: Bird's Nest Stadium uses 42,000 tons of steel and has a span of 333 meters
Industrial Plants: Tesla Factory uses 90% steel structure, shortening construction period by 6 months.
Emerging Potential Areas
Assembled Homes: Zhejiang plans to have 15%16 of steel structure homes in 2025, with 10% lower cost than PC structures
Medical and Education Buildings: Modular Wards Achieve 48-Hour Rapid Expansion, School Gymnasium Spans Demand Adaptive Steel Structures
Emergency Facilities: Square Cabin Hospital Deploys Thousands of Beds in 3 Days Using a Boxed Room System
Future Development Trends
At the policy level, the Ministry of Housing and Construction (MOHSC) has clarified that the proportion of steel structure in new assembled buildings will be increased to 30% in 2025. The direction of technological upgrading includes:
R&D of fire-resistant weathering steel (target fire-resistant time limit of 2 hours without protection)
Intelligent construction convergence (welding robot penetration rate target of 80%)
3D printing node technology (reduce the cost of shaped structures by 20%)
