New Type Housing Project Prefabricated Components

New type housing project prefabricated components are a core part of the prefabricated building field. They achieve efficient, environmentally friendly, and precise construction modes by industrially producing building components and assembling them on-site.

Main Types and Technologies

Prefabricated components cover three major categories: panel-based prefabrication, box-based prefabrication, and frame-based prefabrication. The technological systems include prefabricated concrete structures and steel structures. There is a wide variety of components, encompassing basic products such as beams, slabs, walls, and columns, as well as modular building units with higher integration levels. Modular construction, as an advanced form of prefabricated building, breaks down buildings into independent modules (such as ceilings, walls, bathroom waterproof layers, etc.). These modules are manufactured in factories and then transported to the site for assembly, forming a construction mode similar to 'building with building blocks'.

Construction Process Characteristics

Taking reinforced concrete prefabricated components as an example, their construction requires the collaboration of manual labor and machinery. For instance, a double-layer wall is composed of concrete slabs connected by two layers of welded wire mesh. It is lightweight and entirely made of reinforced concrete. During construction, a light-duty crane lifts the panels, and workers need to ensure they are level and perpendicular to the ground. After installation, concrete is used to fill the structural space to form an integral wall. This process combines the precision of industrial production with the flexibility of on-site assembly.

Core Advantages

1. Significantly Shortened Construction Period: Through parallel operations in factories and automated production lines, modular construction reduces the construction period by more than 60% compared to traditional buildings. For example, a public housing project in Shenzhen used 6,028 concrete modules for assembly, and the completion and delivery time was shortened from 2.5 - 3 years to 1 year.
2. Outstanding Environmental Protection and Energy Efficiency: Factory-based production reduces on-site noise, dust, and construction waste. In Fujian and other places, through policy support, industrial bases have been established, achieving a reduction in construction waste of more than 70%.
3. Precise and Controllable Quality: Each prefabricated component is equipped with a detailed 'ID card' (including project name, product model, and production date). The design precision controls errors in millimeters, ensuring stable building quality.

Market and Prices

Chinese prefabricated houses have been selling well overseas. In the first four months of 2026, the export value of movable houses in the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%. Market research institutions predict that the global market size of modular construction will exceed 142.8 billion US dollars by 2030. In terms of prices, prefabricated components vary depending on their types and specifications: the wholesale price of reinforced concrete prefabricated houses (combined integrated houses) is about 450 yuan, the wholesale price of steel-framed concrete lightweight floor slabs is about 480 yuan, and the quoted price of grouting mesh house wall construction equipment is about 168,000 yuan.
