Light Steel Structure Buildings
The Light Steel Structure Building is a single-layer rigid-frame system engineered for rapid deployment and cost efficiency. Combining hot-rolled H-beams with high-strength bolted connections, it achieves 20-30% lighter weight versus traditional steel. Factory-prefabricated components enable 60% faster assembly, completing projects 40-50% quicker. Its triangular portal frame supports 48m column-free spans for warehouses/hangars. Standardized production ensures ±2mm accuracy, while 275- 355MPa galvanized steel offers 50-year corrosion resistance in harsh environments.
Strategic dimensioning maximizes economic benefits
Span Optimization: Multi-span configurations beyond 48m reduce steel usage by 40% versus single spans, while maintaining 6-9kN/m² roof load capacity.
Column Spacing: Economical 8-9m spacing under standard loads (0.3kN/m² roof, 0.5kN/m² wind), adjustable to 6-7m for heavy industrial facilities (>10t crane loads).
Wind/Snow Adaptation: Aerodynamic profiles lower wind coefficients by 15-20%, while sloped roofs (5-10° pitch) prevent snow accumulation in alpine regions.
Engineering Efficiency: Light Steel Structure Building Design Strategies
Optimized Span Design
Light steel structures achieve cost-space equilibrium through intelligent span planning. When maintaining standard vertical loads (6-9kN/m²), expanding single spans to 18-24m increases steel consumption by only 10-15% while delivering:
1. 25-30% Larger Usable Areas: Column-free layouts for warehouses/retail spaces
2. 18-22% Foundation Savings: Concentrated load transfer reduces footing sizes
3. Multi-Span Advantage: 36 m+ configurations use 40% less steel than equivalent single spans
Technical Insight: ZN House recommends 12m spans for residential villas and 24m spans for light industrial facilities, balancing functionality with ASTM A653-compliant material efficiency.
Precision Column Spacing：
Strategic column placement maximizes structural performance:
| Application | Optimal Spacing | Steel Usage | Load Capacity |
| Standard (0.3kN/m²) | 6–8 m | 45–55 kg/m² | ≤ 5-ton crane |
| Heavy-Duty (0.7kN/m²) | 4–5 m | 70–85 kg/m² | 10–15-ton crane |
Critical considerations include:
- Wind/Snow Adjustments: Coastal regions require 15% tighter spacing for 0.6kN/m² wind loads
- Seismic Compliance: Zone 4 areas demand 8 mm-thick column bases (AISC 341-16 standard)
Cost Threshold: Exceeding 8m spacing increases purlin costs by $12-15/m²

ZN House delivered a full-cycle industrial solution for this 21,000㎡
facility, integrating design, fabrication, and construction. Our cross-functional teams executed precision-engineered steel structures with 8m column-free spans, optimizing workflow for heavy pipe storage. Advanced BIM coordination reduced material waste by 15%, while modular prefabrication enabled 40% faster on-site assembly versus traditional methods.
Australian Aircraft Hangar
Time-Critical Mega Project
Facing a 6-month deadline for a 120 m-span maintenance hangar, ZN House deployed:
Just-in-time manufacturing of 550MPa steel components (±1.5mm tolerance)
Parallel installation workflows achieving 35 modules/day assembly rates
Wind-load optimization for 200km/h cyclonic conditions (AS/NZS 1170.2 compliant)
The project was completed 18 days ahead of schedule, saving $2.1M in potential delay penalties.
