40 FT Expandable House
40 ft expandable house is a movable and expandable modular house designed based on a 40-foot container. It is often used in temporary residence, emergency housing, outdoor camps, mobile offices and other scenarios.
🌟 Product Features
High-strength Modular Steel Structure Frame
The 40 ft expandable house uses Q355B low-alloy high-strength steel to build the frame, with a yield strength of 355 MPa, which is about 25% higher than ordinary building steel. The modular design is connected by high-strength bolts to form a stable spatial force system that can withstand a 12-level strong wind and a 7-level earthquake. The steel surface is hot-dip galvanized with a zinc layer thickness of 85 microns, which effectively prevents rust and extends the service life of the structure to more than 50 years.
High-efficiency Composite Insulation Wall Structure
The wall adopts a three-layer composite structure of "outer color steel plate + middle polyurethane insulation layer + inner fireproof gypsum board". The 0.5 mm thick aluminum-zinc color steel plate has an impact strength of 150J/㎡ and has excellent wear resistance and corrosion resistance; the thermal conductivity of the 100 mm thick polyurethane insulation layer is as low as 0.024W/(m・K), and the thermal insulation performance is 60% higher than that of traditional brick-concrete walls; the inner layer of 12 mm fireproof gypsum board has a fireproof grade of A1, which does not burn in case of fire and maintains structural integrity for more than 4 hours.
Flexible Hydraulic Expansion System
Electric hydraulic expansion devices are installed on both sides of the house, with a single-side expansion width of 1.2 meters, and the usable area can be increased by 24 square meters after expansion. The hydraulic system adopts dual-cylinder synchronous drive technology, and the pressure error is controlled within ±0.5MPa to ensure a smooth expansion process without tilting.
