1. Introduction
The double wing expandable container house is designed in a modular way, so that the house can be pre-assembled in the factory. On site, you only need to simply splice the double wing expansion parts to achieve rapid space expansion. It is based on a flexible connection system to ensure that the double wings are smoothly unfolded and firmly locked, providing users with a spacious and comfortable living or working space.

3. Advantages
Sturdy And Durable
The double wing expandable container house uses 50/75 EPS board with a compressive strength of 150-200 kPa. The frame is reinforced and can withstand 12-level wind force, with a service life of about 20 years.
Waterproof
The roof and walls of the double wing expandable container house are made of waterproof board with a coating thickness of more than 2mm. The joints are sealed with sealing strips, and there will be no internal leakage during heavy rain (100mm/h).
Heat Insulation
The walls of the double wing expandable container house are filled with insulation materials with a thermal conductivity as low as 0.03W/(m・K) to block heat conduction.
4. Manufacturing Process
