3) Huisheng Product performance

Our expandable container house features a high-strength steel structure combined with a modular fold-out design, delivering excellent performance in structural safety, environmental adaptability, and long-term durability.

1. Wind Resistance
The main structure is made of high-strength galvanized steel, with reinforced load-bearing components.
Steel thickness options of 2.3mm / 2.5mm / 3.0mm are available to meet different project requirements, ensuring strong resistance to high winds and typhoon conditions.

2. Seismic Resistance
The modular steel structure provides excellent flexibility and integrity, allowing it to absorb and distribute seismic forces effectively.
Optimized connection joints help minimize structural damage during earthquakes, making it suitable for seismic-prone regions.

3. Waterproof Performance
The roof and wall systems are designed with multi-layer waterproof protection.
Critical joints are sealed with waterproof strips and professional sealing treatments, ensuring reliable performance in heavy rain and long-term wet environments.

4. Moisture & Corrosion Resistance
All steel components are hot-dip galvanized and treated for corrosion resistance, offering strong protection against moisture and rust.
The wall and flooring systems are designed with moisture barriers, effectively preventing dampness and extending the service life, especially in coastal or high-humidity areas.

5. Long-Term Durability
With optimized steel thickness selection, wall systems, and insulation solutions, the expandable container house can easily achieve a service life of over 20 years, while allowing for future maintenance and upgrades.
