Structural Performance and Safety

• Earthquake Resistance (Shock Resistance): LSS buildings excel in seismic zones due to their high strength-to-weight ratio and ductility. The flexible steel framework can absorb and dissipate seismic energy, reducing structural damage during earthquakes. With a shock resistance rating of up to 9 magnitudes, LSS outperforms traditional masonry or concrete structures, which are more brittle. For example, in regions like Japan and California, LSS homes have demonstrated superior resilience during seismic events, minimizing casualties and property loss.
• Ветроустойчивость: Designed to withstand extreme winds (e.g., 70m/s hurricanes, equivalent to Category 5 storms), LSS structures use aerodynamic shapes and robust steel frames. The modular design allows for reinforced connections, ensuring the building remains intact under high wind loads. This makes LSS ideal for coastal areas prone to typhoons or hurricanes, where traditional buildings often suffer structural failures.

Durability and Longevity

• Service Life: The main steel structure, when properly galvanized or coated, resists corrosion and rust, offering a service life of up to 99 years. Unlike wood (prone to rot, pests) or concrete (susceptible to cracking, weathering), steel requires minimal maintenance. This longevity reduces lifecycle costs and ensures the building remains functional for decades, making it a sustainable investment.
• Fireproofing: Steel’s high melting point (around 1370°C) combined with fire-resistant coatings or insulation materials provides fire resistance of 1–4 hours. This exceeds building code requirements in most regions, enhancing occupant safety. In fire-prone areas, LSS buildings offer peace of mind, as steel does not contribute to fire spread (unlike wood) and maintains structural integrity longer during fires.

Thermal and Acoustic Performance

• Heat Insulation: Composite walls (e.g., 200mm thick) with high thermal resistance (3.2 m²K/W) offer superior insulation, reducing heating/cooling energy consumption. This is 11 times more efficient than brick walls, leading to significant energy savings (65% compared to traditional buildings). In cold climates, LSS buildings retain heat better, while in hot regions, they stay cooler, lowering HVAC costs.
• Sound Insulation: Exterior walls (65dB sound reduction) and interior walls (45dB) create a quiet living environment. The steel framework, combined with insulation materials (e.g., rock wool, fiberglass), blocks external noise (traffic, machinery) and minimizes internal sound transmission (e.g., between rooms). This is crucial for residential and commercial spaces (e.g., offices, hotels) where acoustic comfort is essential.

Environmental Sustainability

• Recyclability: Steel is 100% recyclable, with most accessories (bolts, panels) also recyclable. LSS construction generates less waste (prefabricated components reduce on-site cutting/leftovers) and lowers carbon emissions. Compared to concrete (high cement carbon footprint) or wood (deforestation concerns), LSS aligns with circular economy principles, reducing environmental impact throughout the lifecycle.
• Energy Efficiency: Beyond insulation, LSS buildings use energy-efficient construction methods (prefabrication, quick assembly), reducing energy consumption during building. New insulation materials (e.g., aerogel, vacuum-insulated panels) further enhance energy savings, making LSS a cornerstone of green building certifications (LEED, BREEAM).

Space Utilization and Cost Efficiency

• Usable Area: Thin steel walls (compared to thick brick/concrete walls) increase usable floor area by 5–13%. This is a game-changer for urban housing, where space is premium. For example, a 100m² LSS home can offer 10–13m² more usable space than a traditional build, maximizing property value.
• Construction Speed: Prefabricated steel components (manufactured off-site) enable quick assembly, saving 2/3 of construction time. Reduced labor hours (no bricklaying, concrete curing delays) lower labor costs, while faster project completion accelerates return on investment (e.g., rental properties, commercial buildings).

Design Flexibility

• Aesthetic Versatility: Steel frames support diverse architectural styles, from modern minimalist to classic designs. Large spans (open floor plans) and flexible layouts (e.g., mezzanines, cantilevers) allow creative freedom. Cladding options (brick, stone, metal panels, glass) further enhance visual appeal, making LSS suitable for residential, commercial, and public buildings (e.g., schools, hospitals).

Global Adoption and Case Studies

• International Success: LSS is widely used in countries like Australia (bushfire-prone regions, thanks to fire resistance), New Zealand (seismic zones), and European nations (energy-efficient housing). In China, LSS residential projects are growing, driven by government initiatives for green building and urbanization.
• Case Example: A 3-story LSS residential complex in California (earthquake-prone) was built in 6 months (vs. 18 months for traditional construction), withstood a 7.0 magnitude earthquake, and achieved LEED Gold certification due to energy efficiency and recyclability.
