Hunan Prefabricated House Finished Product

The finished products of prefabricated houses in Hunan are presented in the form of modular buildings, featuring short construction periods, controllable quality, energy conservation, and environmental protection. There are successful application cases both domestically and internationally.

Definition and Characteristics

Prefabricated houses, also known as modular buildings, divide a building into independent modules. The manufacturing of ceilings, floors, water and electricity pipelines, etc., is completed in factories, and then the modules are transported to the construction site for assembly. Compared with traditional construction techniques, they have significant advantages:

• Short construction period: Construction accuracy is controlled in millimeters, greatly reducing construction waste. For example, in the first phase of the Indonesian modular dormitory project undertaken by Jinlinjia, it took only 2 months from the arrival of goods at the port to installation and delivery. For the same amount of work, traditional local construction usually takes about 2 years, representing a 90% reduction in the construction period.
• Controllable quality: Prefabricated on factory assembly lines, they can better ensure building quality.
• Energy conservation and environmental protection: They conform to the concept of green buildings, reducing resource waste and environmental pollution during the construction process.

Corporate Achievements

• Jinlinjia: As a subsidiary of Hunan Construction Investment Group and a leading enterprise in the provincial prefabricated building industry chain, it has a wide range of businesses. Its Indonesian modular dormitory project has achieved remarkable results. After the successful delivery of the first-phase project, it won the bid for the second-phase project based on efficient performance. Currently, all building modules for the second-phase project have been shipped in full from the intelligent production base in Xiangtan, and the Indonesian site has entered the stage of efficient hoisting and construction. The company's business has expanded to 12 countries and more than 30 cities worldwide, with a total floor area of over 300,000 square meters. The contract amount for overseas projects has increased significantly, reaching 36.6571 million yuan for the whole year of 2025, 21.3287 million yuan in the first half of this year, and is expected to exceed 50 million yuan for the whole year.
• Hunan Xiangtan: There is a production process for new-type rural villa prefabricated cement houses in Xiangtan, Hunan, covering multiple links such as steel bar cutting, beam-column welding, and wall steel bar welding. The production of prefabricated cement houses is completed through a series of processes.
• Zhang Yue's team: Zhang Yue, from Hunan, has developed a new version of stainless-steel prefabricated house material that is ten times lighter than concrete and will deform but never collapse under strong earthquakes. In 2020, negative-pressure wards were urgently delivered to South Korea, and about 130,000 square meters have been sold globally over the past five years.
