Prefabricated Housing Components

Prefabricated housing components are a core part of the prefabricated construction sector, offering significant advantages such as efficiency, environmental friendliness, and controllability through industrialized production of building components and on-site assembly.

I. Main Types and Technologies

Prefabricated housing components encompass a variety of types and technological systems:

1. Types: These include panel-based prefabrication (e.g., prefabricated wall panels and floor slabs), box-based prefabrication (e.g., integrated bathroom modules), frame-based prefabrication (e.g., prefabricated beam-column structures), and modular buildings with higher integration levels (where buildings are broken down into independent modules, manufactured in factories, and assembled on-site).
2. Technologies: Primarily based on prefabricated concrete structures and steel structures, components include prefabricated beams, slabs, walls, and columns. Modular buildings achieve rapid assembly through standardized design. For example, a certain affordable housing project utilized 6,028 concrete modules, reducing the construction period from 2.5-3 years to just 1 year.

II. Core Advantages

1. Efficiency Improvement: Industrialized production reduces on-site construction time. An industrial park, through automated production lines, can deliver 20,000-30,000 modules annually, shortening the construction period by over 60% compared to traditional buildings.
2. Environmental Protection and Energy Efficiency: On-site labor is reduced by approximately 50%, significantly lowering noise and dust pollution, and meeting green building standards.
3. Quality Control: Factory-standardized production ensures component precision, reduces human errors, and enhances overall building quality.
4. Cost Optimization: In the long run, mass production reduces unit costs. Overseas customers have high repurchase rates due to cost advantages, such as the continuous increase in follow-up orders for a hotel project in Papua New Guinea.

III. Application Scenarios and Market Performance

1. Application Scenarios: Widely applicable to hotels, apartments, dormitories, office buildings, hospitals, and data centers, meeting diverse construction needs.
2. Market Growth: China's prefabricated housing exports have performed strongly. In the first four months of 2026, export volume from the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%. From 2015 to 2025, export volume nearly tripled over a decade, with a growth rate of 45% in the first quarter of 2026. Overseas customers, such as those in the UK, choose Chinese products due to cost advantages.

IV. Price Range

Prices for prefabricated housing components vary significantly depending on type and specifications:

• Reinforced concrete prefabricated integrated houses cost approximately 450 yuan each.
• Concrete housing molds range in price from 57 yuan to 168,000 yuan, depending on specific needs.

China has formed a complete technological system and industrial cluster. In the future, with technological advancements and expanding market demand, prefabricated housing components will further drive the industrial transformation of the construction sector.
