Prefabricated expandable container houses, also known as double-wing expandable container houses, are a fully prefabricated housing solution. They use containers as the basic structure. This type of expandable house has an expandable double-wing structure. Without increasing the overall transportation size and weight, this design allows the interior space to be significantly increased by unfolding the double wings to meet different residential, office or commercial needs.

When the double-wing expansion container is transported and stored, the double wings are folded or retracted to save space and facilitate handling. When needed, the double wings can be unfolded to form a more spacious and practical interior space. This design not only improves the flexibility and adaptability of the container, but also enables it to better meet various temporary or long-term residential and office needs.

The expandable folding container house uses light steel materials such as galvanized high-strength square tubes and galvanized angle irons as frames, double-sided color steel composite panels as walls, and high-strength hinges are used to link the frames. The expanded house space is nearly 3 times larger than before it was unfolded. 20-foot and 40-foot expansion houses can be made, and they can also be customized according to customer needs.
