Introduction of light steel structure villa in coastal area

I. Core Characteristics

1. Extreme climate adaptability

• Typhoon resistance

Adopting light steel keel frame and plate rib structure system, it can withstand grade 12 typhoon (wind speed ≥70m/s), encrypting keel spacing (≤400mm) and configuring wind-resistant clip fasteners on roof, and adopting impact-resistant calcium silicate board (flexural strength ≥8MPa) on the external wall surface to enhance the overall wind-resistant performance.

The foundation is designed with pre-buried anchor bolts (depth ≥1.2m) and wind-resistant cables to enhance the anchoring stability of the building and the foundation.

• Seismic performance

The steel material has excellent ductility and absorbs seismic energy through flexible deformation, which can withstand a 9-degree earthquake (0.4g acceleration), and the degree of structural damage is about 60% lower than that of traditional brick-concrete buildings.

Multi-bay truss + redundant bracing design, single point failure does not affect the overall safety.

2. Corrosion and Moisture Resistant Design

• Material anti-corrosion technology

The main body adopts aluminum-zinc-plated light steel keel (plating ≥275g/㎡), and the surface is sprayed with epoxy resin layer to form a tetrameric crystalline barrier, with salt spray corrosion resistance life of ≥50 years.

Doors and windows adopt bridge-breaking aluminum + double-layer Low-E glass (thickness ≥5+5mm) to reduce condensation infiltration.

• Moisture-proof system

One-way breathing paper moisture-proof layer is set on the wall to isolate outdoor moisture and discharge indoor moisture, and the foundation is paved with SBS coil moisture-proof layer to reduce the risk of salt spray erosion.

The roof is designed with a slope of 30° or more + siphon drainage pipes, and the permeable concrete layer on the ground prevents water infiltration.

3. Efficient construction and low maintenance cost

• Rapid construction

Factory prefabricated lightweight steel components, the main frame of 200㎡ villa is completed in 15-20 days, and the overall construction cycle is 50% shorter than that of traditional construction.

• Economical and Convenient Maintenance

The comprehensive cost is 1400-1800 RMB/㎡ (including foundation), and the maintenance cost is only 1/3 of that of brick-concrete structure.

Localized damage can be repaired by replacing prefabricated modules without large-scale demolition.

4. Environmental Protection and Comfort

• Energy-saving and environmental protection

The thermal insulation layer is filled with rock wool (thermal resistance value ≥4.24K-m²/W) or glass wool, adapted to high humidity climate, and energy consumption is 30%-40% lower than that of traditional buildings.

The material can be recycled up to 80%-100%, reducing construction waste.

• Optimization of living experience

Sound insulation ≥65dB for exterior walls and ≥44dB for interior walls, with double-layer Low-E glass doors and windows to reduce outdoor noise interference.

The utilization rate of indoor space is up to 90%, with thin walls and large span, and the design is flexible to meet personalized needs.

II. Detailed parameter table

Main material: aluminum-plated zinc light steel keel (thickness 0.84-2.0mm)

Wind pressure resistance level: ≥0.85kN/㎡ (resistant to grade 12 typhoon)

Seismic grade: 9 degrees (0.4g acceleration)

Wall sound insulation volume: external wall ≥ 65dB, internal wall ≥ 44dB

Insulation layer thickness: 50-150mm (adaptable to extreme climate)

Design life: ≥50 years (regular maintenance)

III. Optimization of coastal adaptation technology

• Anti-salt spray corrosion

Aluminum-zinc-plated steel skeleton surface sprayed with epoxy resin layer enhances salt spray resistance; doors and windows adopt bridge-breaking aluminum + double-layer Low-E glass (thickness ≥5+5mm) to reduce the risk of condensation.

• Typhoon resistant reinforcement

The foundation is pre-buried with ground bolts (depth ≥1.2m), and additional wind-resistant cables are installed on the roof; the external wall surface layer adopts impact-resistant calcium silicate board (flexural strength ≥8MPa).

• Rapid Drainage System

The roof is designed with a slope of 30° or more, with siphon drainage pipes; the ground is set up with a permeable concrete layer to prevent water infiltration.

IV. Typical Application Cases

Fujian coastal vacation villa: 150mm thick rock wool insulation layer + PV roof (daily power generation of 3-5kW) is used to realize energy self-sufficiency.

Self-built house in Hainan typhoon area: encrypted steel skeleton spacing (300mm) + double-layer respiratory paper moisture-proofing, verified by 12-level typhoon test.
