Hanxing Double-Wing Expandable House

The Hanxing Double-Wing Expandable House is a modular integrated building solution based on a light steel structural system. It features a foldable and expandable design built on a standard container unit, with two side wings that can be horizontally extended outward. This innovative structure enables a compact form during transportation and a spacious layout during use.

After expansion, the usable floor area increases by 40% to 100% compared to the folded state. Combining high transport efficiency, rapid deployment, flexible space configuration, strong structural performance, and reusability, it is an ideal solution for temporary offices, accommodation camps, emergency housing, tourism lodges, and commercial pop-up applications.

2. Core Structure And Technical Features

Double-Wing Expansion System

The structure consists of a fixed central module with two side wings connected through high-strength hinges and rail systems. During expansion, the wings extend smoothly outward, forming a seamless connection with no height difference, no leakage, and no thermal bridging.

A hydraulic synchronization system ensures both wings expand evenly with minimal deviation, preventing structural stress or deformation. In case of power failure, manual operation is available.

After expansion, the structure is secured with mechanical locking and sealed with waterproof strips, ensuring excellent air tightness and water resistance.

Hidden pipelines for electrical, water, and HVAC systems are pre-installed within the structure and automatically connect during expansion, improving installation efficiency by more than 60 percent.
