Light steel structure villa suitable for modern housing

Light Steel Structure Villa has become the preferred solution for modern housing in terms of safety, comfort and sustainability through high-strength light steel skeleton, factory prefabrication process and low-carbon environmental protection technology.

I. Core structure design

Main frame:

G550 grade aluminum-zinc-plated light steel keel as the main body, wall thickness 0.84-2.56mm, molded by cold-rolling process, plating thickness ≥80 microns, corrosion-resistant life ≥50 years.

Adopting C-type steel or H-type steel column, with truss floor bearing plate, the second floor floor bearing capacity ≥1 ton/㎡.

Connection process:

Self-tapping screws dry assembly, seismic performance of more than 9 levels, wind resistance level ≥ 12.

II. Materials and Parameters

Wall IEC self-insulation system (OSB board + fiberglass wool + calcium silicate board), heat transfer coefficient ≤ 0.3W/(m²-K), sound insulation ≥ 65dB Winter indoor-outdoor temperature difference ≤ 5°C

Roofing Asphalt tile/metal sculpture plate + waterproof breathable membrane, or photovoltaic integration metal tile (average daily power generation 15kWh/㎡) Waterproof life ≥ 30 years

Foundation Pile foundation (depth 1.5-3m), adapted to complex terrain, reducing earth excavation by 80%56 Settlement error ≤2cm

III. Performance Advantages

Safety:

Cage structure design, strong horizontal load resistance, no risk of wall collapse during earthquakes;

Fireproof calcium silicate board (Class A fireproof) and formaldehyde-free paint (VOC≤0.03mg/m³) guarantee the safety of residence.

Environmental friendliness:

Steel is 100% recyclable, construction waste is reduced by 80%, and comprehensive carbon emissions are 40% lower than traditional buildings;

The rainwater recycling system has a daily processing capacity of ≥2 tons, increasing the water saving rate by 40%.

Economy:

Comprehensive cost of 1500-2500 RMB/㎡ (including decoration), construction cycle 30-45 days, 60% shorter than traditional buildings;

Low maintenance cost (anti-corrosion maintenance every 10 years), full life cycle cost savings of 30%.

IV. The construction process and cycle

Standardized process:

Design phase: 3D modeling and load calculation (5-7 days);

Factory prefabrication: light steel keel cutting and galvanizing (15-20 days);

On-site assembly: modular assembly + decoration (30-45 days).

Quality control:

Node connection precision error ≤2mm, wall verticality error ≤3‰.

V. Application Scenarios and Cases

New rural residence: Shandong Hailian project adopts metal sculpture plate outer wall + photovoltaic roof, enjoying 120 yuan / ㎡ government subsidies;

Ecological culture and tourism: Hutuo River Buyeo integrates vertical greening system to reduce room temperature by 3-5℃ in summer;

Urban housing: modular community in Chengdu realizes whole-house intelligent temperature control and reduces comprehensive construction costs by 22%.

VI.  light steel structure villa style comparison: modern simple VS European classical

Through the flexibility of light steel structure and high prefabrication rate (≥90%), both styles can realize the goal of rapid construction and low carbon.

1. Modern Simple Style

Design Elements

Suitable for users who pursue a sense of technology, environmental protection and high cost-effectiveness, especially for small and medium-sized households and smart homes.

Appearance: Geometric lines, large glass curtain walls and metal engraved panels are combined with low-saturation colors (e.g. grey, white and curry) to create a sense of minimalist technology.

Space layout: open design (e.g. integration of guest dining room), reducing partitions, maximizing light and transparency, suitable for small and medium-sized households of 120-150 square meters.

Intelligent Integration: Integration of intelligent lighting system and Low-E insulating glass, realizing automatic dimming and temperature control, reducing energy consumption by 40%.

Materials and Parameters

Main structure: G550 grade aluminum-zinc-plated light steel keel (wall thickness 0.84-2.56mm), with truss floor bearing plate, floor bearing capacity ≥1 ton/㎡.

Facade: Aluminum or stone dry-hanging finish, waterproof and stain-resistant paint, weather-resistant life ≥ 30 years.

Environmental protection index: VOC emission ≤0.03mg/m³, sound insulation ≥65dB, comprehensive carbon emission 40% lower than traditional buildings.

2. European classical style

Design elements

Suitable for mansion users who emphasize sense of ceremony, large space and classic aesthetics, and need to reserve a high decorative budget.

Appearance: Symmetrical façade, Roman columns, sloping roof and relief decorations, matched with warm-colored stone or culture stone, restoring the elegant temperament of European-style manor.

Space layout: open-air living room (floor height ≥ 6 meters), rotary staircase, independent garage, suitable for 200-400 square meters mansion.

Decorative details: carved plaster lines, arched doors and windows, fireplace design, strengthening the classical aesthetics.

Materials and Parameters

Main structure: H-type steel columns + cast-in-place floor slabs, seismic grade ≥ 9, wind grade ≥ 12.

Facade: Stone-like paint or real stone paint spraying, waterproof life ≥ 30 years, suitable for mountain/wetland terrain.

Thermal insulation performance: IEC self-insulated wall (heat transfer coefficient ≤ 0.3W/(m²-K)), winter heating cost as low as 8 RMB/㎡.
