Guizhou Prefabricated Component Houses

Prefabricated component houses in Guizhou mainly adopt the prefabricated construction method, where some or all of the building components are prefabricated in factories and then directly assembled at the construction site.

Production of Prefabricated Component Houses in Guizhou

In Guizhou, there are large-scale prefabricated factories in the southwest region with a rich variety of prefabricated component products, such as China Construction Science & Technology Guizhou Co., Ltd. It produces more than 10 categories of products, including prefabricated stairs, composite slabs, composite walls, etc., basically covering all types of products that can be produced through prefabricated construction.

Advantages of Building Houses Using the Prefabricated Construction Method

• Efficient and Environmentally Friendly: The water consumption per square meter of building area can be reduced by more than 60%, and energy consumption by more than 30%. By transferring a large amount of traditional on-site work to factory operations, labor costs can be saved by about 70%, and construction time by about 30%. At the same time, it reduces on-site wet work and formwork usage, significantly lowering construction dust and noise pollution, as well as reducing the generation of construction waste.
• Quality Controllable: Building components produced in factories are marked with QR codes. By scanning these codes, detailed information about the manufacturing and installation of each prefabricated component can be obtained, such as production date, production workers, raw materials, and inspection quality, making the on-site assembly work both precise and efficient.
• Good Performance: Taking prefabricated reinforced concrete shear wall structure residences as an example, shear walls, as the core load-bearing components of the building, play a crucial role in resisting horizontal loads and providing structural stiffness, ensuring the stability of the house in the face of natural disasters such as strong winds and earthquakes. In addition, they have good thermal insulation properties, effectively reducing energy consumption.
• Flexible Design: Despite the use of prefabricated component technology, the design offers flexibility and diversity. Whether it is the layout of the apartment, the style of the exterior facade, or the interior decoration design, it can be customized according to needs and preferences.

Development Status

It is expected that by the end of 2025, the newly started prefabricated building area in Guiyang will account for more than 60% of the newly built building area. From 2021 to 2023, the newly started prefabricated building areas in Guiyang were approximately 2.04 million, 3.13 million, and 3.47 million square meters respectively, accounting for approximately 22%, 32%, and 43% of the newly built building area. In 2022, the newly started prefabricated building area in the city was about 3.13 million square meters, accounting for 31.93% of the newly built building area, successfully achieving the annual target.
