Expandable House

Expandable House is a kind of expandable house, which realizes the flexible space change through specific design. It's usually constructed with prefabricated modules, and its main structure is easy to disassemble, assemble and transport. When it's necessary to enlarge the usable area, it can expand the hidden additional parts like expanding rooms or adding bedrooms with the help of mechanical devices or manual operation, so as to quickly increase the available space and meet different demands such as temporary or long-term living and office.

Hot-Dip Galvanized Steel Structure
Expandable House uses hot-dip galvanized steel for its main frame. The zinc layer permanently bonds with the steel, forming a rust-proof barrier ≥85μm thick. This process ensures Expandable House remains rust-free for 30-40 years in humid or acidic environments, tripling the lifespan of ordinary painted steel structures and eliminating strength loss from metal oxidation.

Structural Waterproof Design
Expandable House integrates wall and roof connections with continuous bending technology, eliminating traditional seams. Combined with EPDM seals and hidden drainage channels, it maintains indoor humidity below 65%RH even during 10-level storms (wind speeds 24.5-28.4m/s), doubling waterproof performance over conventional mobile homes.

Sandwich Composite Wall Panels
Expandable House walls consist of 0.5mm galvanized steel + flame-retardant rock wool + moisture-proof gypsum board, achieving Class A fire resistance (120 minutes under open flames). High-density rock wool (120kg/m³) reduces thermal conductivity to 0.038W/(m·K), maintaining a 15°C indoor-outdoor temperature difference in -15°C environments, cutting heating energy use by 40%.

Earthquake and Wind Resistance
Expandable House absorbs 80% of seismic energy with elastic damping supports, meeting 10-level earthquake resistance. Robot-welded galvanized steel frames withstand wind pressure up to 5.5kN/㎡ (10-level wind), tripling stability over traditional structures.

Lightweight Modular Design
Expandable House units weigh 2000-5500kg, allowing transport via trucks or cranes. Pre-installed windows, doors, and electrical systems restore water and power within 2 hours of relocation, eliminating the need for secondary decoration and meeting frequent relocation needs.
