Chongqing Box Prefabricated Housing

Chongqing box prefabricated housing is a modular, movable prefabricated building centered around a steel structure framework, represented by packed box-type houses, featuring high structural strength, diverse functions, and a wide range of application scenarios.

I. Product Features and Classifications

Chongqing box prefabricated housing mainly features packed box-type houses. Its core structure consists of cold-formed thin-walled steel frames, rock wool or polyurethane sandwich panel walls, doors, windows, and internal piping modules. Compared to traditional movable panel houses, its structural strength is increased by over 30%, with a fire rating of Class A, superior thermal insulation performance, and customizable exterior designs to meet diverse needs. The products are classified into three categories:

• Standard Type: Suitable for basic scenarios such as temporary offices and dormitories on construction sites, with a unit cost of approximately 15,000 to 20,000 yuan;
• Customized Type: Meets personalized needs for scenic area homestays and commercial exhibition halls by adjusting dimensions, exteriors, or functional modules (e.g., adding bathrooms or kitchens);
• High-End Type: Integrates photovoltaic roofs and smart home systems, with a unit cost of up to 30,000 yuan, suitable for high-quality projects with long-term use.

II. Manufacturing Process and Regional Advantages

Chongqing enterprises use automated welding equipment and CNC cutting machines to control product dimensional errors within ±2mm, ensuring rapid installation accuracy. The local industrial chain is mature, with steel and panel materials transported at low cost via the Yangtze River waterway or railways, complemented by just-in-time delivery from surrounding suppliers, shortening the production cycle to 15-20 days. Additionally, Chongqing's well-developed multimodal transportation network enables quick distribution of finished products to the southwest region and across the country.

III. Application Scenarios and Market Trends

Current application scenarios include:

• Urban Construction: Used as temporary command centers and material warehouses in Chongqing's rail transit and bridge projects;
• Cultural and Tourism Development: Customized box houses are used to create Bayu-style homestays in scenic areas such as Wulong and Nanchuan;
• Emergency Disaster Relief: Their waterproof and wind-resistant properties, along with the ability to be erected in 4 hours, make them the preferred choice for post-disaster resettlement.
  In terms of market trends, enterprises are enhancing added value through technologies such as photovoltaic integrated roofs and prefabricated interiors, with some products already exported to Southeast Asian markets.

IV. Usage Precautions

• Site Foundation: Concrete strip foundations are required for sloped or soft soil areas to prevent settlement;
• Compliance Approval: Registration with the local housing and construction department is necessary, and selecting qualified manufacturers ensures compliance with drawings;
• Cost Control: For short-term projects, a “lease + purchase” model is recommended, while direct purchase offers lower costs for long-term use (averaging 15%-20% lower per square meter).
