prefab tiny light gauge steel home 

modular design + lightweight materials

prefab tiny light gauge steel home with seismic and wind resistance, 

fast construction, environmental protection and economy as the core advantages, 

suitable for rural self-build, cultural and tourism lodging and emergency housing scenarios, 

and become an important direction of the upgrade of the modern construction industry.

I. Definition and Core Characteristics

• Structural composition

Cold-formed thin-walled steel profiles (thickness 1.2-2.0mm) are used as the load-bearing frame, with rock wool insulation (density ≥80kg/m³), 

calcium silicate board or OSB board enclosure to form a modular box unit.

The prefabrication rate of the factory can reach 90%, and it is quickly assembled on site by bolts or snap fasteners, 

and the area of a single box unit is mostly concentrated in 34-200 square meters.

• Technical Advantages

Seismic and wind resistance: seismic up to grade 9, wind resistance grade ≥ 12, applicable to seismic zones and coastal typhoon areas.

Environmental protection and energy saving: steel can be recycled up to 95%, the thermal insulation layer reduces energy consumption by 30%-50%, in line with green building standards.

II. Performance and Cost Analysis

• Construction Efficiency and Cost

Construction cycle: After the foundation is completed, the main building takes only 10-15 days (within 200 square meters), and the full cycle takes about 1-3 months.

Cost range:

Basic model: 1200-1500 RMB/㎡ (including water and electricity connections);

High-end model: 2500-5000 RMB/㎡ (integrated smart home, photovoltaic system).

• Maintenance Economy

No need for frequent maintenance, coastal areas only need to apply anti-rust coating every 2 years, the maintenance cost is 30% lower than the traditional brick structure.

III. Design Flexibility and Application Scenarios

• Space Innovation

The wall thickness is reduced by 30%-40%, which enhances the use of space by 10%-15% under the same floor area, and supports the layout of open kitchens and multi-functional living areas.

Expandable double-story structure or external terrace to meet individual needs (e.g., 34m2 modular room with integrated sleeping area, fireplace and landscape terrace in the Spanish case).

• Typical applications

Self-built houses: meet the demand for rapid construction of suburban houses with 2 floors or less, with both regional characteristics and modern functions.

Cultural tourism and commerce: scenic lodging and mobile cafes use large glass curtain walls to strengthen the interaction of natural landscape.

Emergency housing: modularized design supports batch deployment, and basic residential functions can be built within 48 hours after a disaster.

IV. Technical Challenges and Solutions

• Rust prevention and durability

Galvanized steel facade + epoxy zinc-rich primer is used in coastal areas, and the life span of salt spray corrosion protection is increased to over 50 years.

EPDM rubber sealing + polyurethane waterproofing adhesive is used at the joints to avoid water seepage and cold bridge effect.

• Fire prevention and safety

Fireproof coating needs to reach A1 level standard, the circuit is protected by flame-retardant pipes, and the smoke sensor is installed ≥1.5 meters away from the cooker.

Technology upgrading: intelligent home, photovoltaic integrated roof and other innovative technologies to accelerate the popularization of products to “zero energy consumption” direction.
