Jinning Container House Production

Container house production in Jinning is represented by Yunnan Yaohui Integrated Housing Manufacturing Co., Ltd. and Yunnan Hehongsheng Prefabricated Building Co., Ltd., which have a complete industrial chain and standardized production capabilities.

1. Company Overview and Production Capacity

Yunnan Yaohui Integrated Housing Manufacturing Co., Ltd., established in 2017, is located in the Qingshan Base of the Jinning District Industrial Park. It mainly engages in the processing of container frame materials, the rental and sales of container mobile homes, and the design and installation of light-steel mobile homes. With a registered capital of 1.2 million yuan, it has a workforce of 20 - 99 people. Yunnan Hehongsheng Prefabricated Building Co., Ltd., founded in 2021, has a registered capital of 20 million yuan. It possesses modern panel production and processing workshops as well as large-scale steel structure welding workshops, with an annual production capacity of 10,000 sets of prefabricated buildings. It is a key enterprise in its细分领域 (sub-sector) in Yunnan Province. Both companies have passed relevant construction qualification certifications and have the ability for large-scale production.

2. Production Process and Quality Control

The core production processes of container houses include:

1. Steel Structure Frame Welding: Hot-dip galvanized cold-formed steel is used, and the frame assembly is completed through automated cutting and welding equipment to ensure structural strength and anti-rust performance.
2. Wall and Roof Panel Prefabrication: Rock wool, glass wool, or polyurethane sandwich panels are used, filled with thermal insulation materials and covered with facing materials to achieve fireproof and heat-insulating functions.
3. Modular Assembly: In the factory, processes such as the pre-embedding of water and electricity pipelines and the installation of doors and windows are completed. Trial assembly tests are carried out before leaving the factory, and only hoisting and splicing are required on-site, shortening the construction period by more than 50%.
4. Quality Control: Companies like Hehongsheng adopt millimeter-level error control standards to eliminate on-site construction hazards, and the product lifespan can reach more than 10 years.

3. Product Types and Application Scenarios

Container house products in Jinning mainly fall into three categories:

1. Packing-box Container Houses: Suitable for construction site dormitories and office areas, they can be stacked in multiple layers and support rapid disassembly and assembly for turnover.
2. Light-steel Stud Houses: Using cold-formed thin-walled light-steel structures with thermal insulation materials filled in the walls, they are suitable for long-term use scenarios such as cultural tourism homestays and scenic area supporting housing.
3. Functional Supporting Houses: Including security booths and environmental protection public toilets, their sizes and layouts can be customized to meet special scenario requirements.

4. Industry Advantages and Policy Support

As a radiation center for Yunnan facing South Asia and Southeast Asia, Jinning District enables companies to build a "domestic production + overseas service" system by taking advantage of its geographical location, reducing logistics costs by more than 30%. In 2024, Hehongsheng's container house prefabricated building project passed the environmental impact assessment approval of the Kunming Municipal Ecology and Environment Bureau, marking a further acceleration in the standardized development of the industry.
