Features of our modular buildings
Durable: Industrial-grade structural reliability
- High-strength steel structure frame: ASTM A572 Gr.50 steel, yield strength ≥345MPa, anti-corrosion galvanized layer thickness ≥80μm, design life over 50 years.
- Composite wall system: outer metal plate + rock wool insulation layer (density ≥120kg/m³) + fireproof gypsum board, fire resistance limit up to 2 hours, sound insulation performance ≥45dB.
Quick installation: process-based construction mode
- Factory pre-installation rate 90%: pre-buried pipelines (standardized electrical/water supply/ventilation interfaces), ground paving and basic decoration are completed inside the module.
- The on-site hoisting cycle is 40% shorter than traditional construction: taking a 1,000㎡ single building as an example, it only takes 15 days to complete module splicing and system joint debugging on site.
Customized design: balance of function and form
- Free layout of non-load-bearing walls: the light steel keel partition system supports arbitrary plane division, and the adjustment cycle is ≤3 days.
- Modular adaptation of the facade: 6 types of surface systems are provided, including metal plates, fiber cement boards, precast concrete hanging panels, etc., and Rainscreen structural ventilation design is supported.
Energy saving and environmental protection: Passive performance optimization
- Thermal performance: The overall U value of the exterior wall is ≤0.35 W/(m²·K), three-glass two-chamber Low-E window (Ug=1.0 W/(m²·K)).
- Material recyclability: The recycling rate of the main steel structure is ≥95%, and the recycling rate of wall materials is ≥80%.
Cost controllable: Industrialized control of the entire process
- Material loss rate ≤3%: The component optimization nesting system based on BIM reduces the steel consumption by 15% compared with traditional construction.
- Labor cost savings: Factory construction reduces on-site labor by 60% and reduces the comprehensive cost by 18-25%.
Multi-scenario adaptation: Standardized interface expansibility
- Load compatible design: Floor live load can be configured from 2.5kN/m² (residential) to 5.0kN/m² (commercial), and floor height supports customization from 2.8m to 4.5m.
- Functional space prefabrication: Module units are pre-integrated with functional units such as bathroom/kitchen/machine room to meet the needs of special scenarios such as medical sterile areas and laboratories.
Factory manufacturing advantages: Why choose us
CNC machining error ≤±1.2mm: Laser cutting and robot welding processes ensure the consistency of module interfaces and eliminate on-site matching deviations.
Full-size 3D scanning quality inspection: Each module is compared with the BIM model by laser scanning before leaving the factory, and the key dimension qualification rate is 100%.
Structural performance verification: module stacking test (8-layer simulated load), seismic table test (meeting GB 50011-2010 8-degree fortification).
Containerized transportation: The module is packaged in standard container size (40HQ) when it leaves the factory, and the global port arrival intact rate is ≥99.5%.
Whether it is a single-story house, a duplex villa, or a multi-story commercial building, we can provide efficient, safe, and industry-standard building solutions!
