Erlianhaote Container House

Erlianhaote container houses focus on innovative construction models and modular design, providing efficient and durable mobile building solutions.

I. Main Product Types and Business Coverage

Erlianhaote container houses mainly include container houses, container mobile houses, packing-box units, mobile panel houses, color-steel houses, and color-plate houses. The business covers multiple locations in Inner Mongolia, such as Baotou, Hohhot, and Ordos, meeting the needs for temporary or permanent buildings in different regions.

II. Construction Model Innovations

1. Factory Prefabrication and On-site Assembly:
   The traditional “on-site construction” model has been transformed into a “factory prefabrication, on-site assembly” process. Using a lightweight steel structure frame, beams and columns bear all loads, while walls only serve for separation and insulation. This reduces the building's self-weight by about 60%, simplifies foundation requirements, and significantly improves construction efficiency.

2. Optimized Interlocking Connectors:
   Interlocking connectors manufactured using cold roll forming technology are introduced. These connectors feature precisely stamped preset slots, allowing components to snap into place during on-site installation without welding or excessive bolts. This design eliminates the weakening of steel strength caused by the heat-affected zone of welding, controls installation errors within 2 millimeters, reduces gaps between walls and frames, and creates conditions for sealing processes.

3. Sandwich Composite Walls:
   The walls adopt a “sandwich” structure with extruded polystyrene foam board (XPS) as the core material, covered on both sides with 0.5-millimeter-thick aluminum-zinc alloy steel plates. The XPS has a thermal conductivity of only 0.028 watts per meter-kelvin, providing five times better insulation than traditional aerated concrete blocks. The aluminum-zinc alloy steel plates are protected against corrosion through electrochemical protection, extending their weather resistance by more than three times compared to ordinary galvanized plates. The XPS core material used by the Erlianhaote company has a density of 35 kilograms per cubic meter, with a compressive strength about 15% higher than similar products in Baotou, making it more suitable for high-rise integrated housing.

III. Features of Packing-Box Units

1. Modularity and Rapid Assembly:
   Using standard shipping containers as core units, structural reinforcement, insulation layer installation, door and window fitting, and pipeline embedding are completed in the factory. On-site work only requires lifting, connection, and external pipeline对接 (docking), shortening construction time and reducing weather impacts.

2. Flexible Spatial Combination:
   Each unit has structural independence, functional completeness, and uniform interfaces. Horizontal alignment creates open spaces, while vertical stacking achieves stable structures using dedicated connectors, meeting elastic demands such as worker camps and commercial offices.

3. Optimized Envelope Structure:
   The steel side panels are internally lined with a moisture barrier, high-performance insulation layer, and decorative lining board, forming a continuous insulation system with thermal performance far exceeding brick walls. Seams and door/window openings are sealed with multi-layer sealing strips, effectively blocking sand and wind intrusion.

IV. Advantages of Container Mobile Houses

They are easy to transport, sturdy and durable, with excellent sealing properties. Based on a standard steel chassis, spaces such as conference rooms and dormitories can be assembled. They are easy to disassemble and assemble, shock-resistant, waterproof, fireproof, and corrosion-resistant, with a service life exceeding 20 years. They are suitable for a wide temperature range (-70°C to +120°C) and are ideal thermal insulation materials for cryogenic engineering.
