Prefabricated House Introduction

Prefabricated houses are a form of construction where building components are industrially produced and assembled on-site. They offer advantages such as short construction periods, reduced pollution, and controllable quality, and are mainly divided into three types: steel, concrete, and wooden structures.

Prefabricated houses, also known as prefabricated modular buildings or modular construction, encompass technologies such as prefabricated concrete structures and steel structures. The components include prefabricated products like beams, slabs, walls, and columns. The building is divided into independent modules, which are prefabricated and inspected in factories for architecture, structure, electromechanical systems, and interior decoration, and then transported to the site for assembly and immediate use.

Significant Advantages:

• Shortened Construction Period: The construction period is reduced by 30% - 60% or more compared to traditional methods. For example, the construction period of prefabricated buildings is 30% shorter than that of traditional methods; modular buildings can reduce the construction period by more than 60% compared to traditional buildings; in a public housing project in Shenzhen, Guangdong, the completion and delivery period was reduced from 2.5 to 3 years to 1 year.
• Reduced Pollution: Significantly reduces noise, dust, construction waste, and traffic congestion at the construction site, which are nuisance factors.
• Controllable Quality: Each component has a detailed 'ID card', including project name, product model, and production date. The position of each steel bar is controlled with millimeter-level precision for error and accuracy.
• Energy Efficiency and Environmental Protection: Favored by the domestic and international construction industries.
• High Adaptability: Can meet the needs of different scenarios.
• Easy Maintenance: Flexible for repairs.
• Cost Savings: Producing hollow prefabricated slabs reduces weight and saves costs.

Diverse Forms:
Prefabricated houses mainly come in three forms: steel, concrete, and wooden structures. Chinese companies have comparative advantages in steel and concrete structures. Steel structures are lightweight, suitable for ocean transportation and high-rise buildings, while concrete structures are closer to traditional living experiences and have high acceptance in the domestic market.

Development Status:
China's prefabricated concrete technology began in the 1950s and was initially applied in specific fields. Existing prefabricated panel houses generally have issues such as weak earthquake resistance, poor sound and thermal insulation, and a service life of about 30 - 50 years. According to market research agency predictions, the global modular building market size will exceed $142.8 billion by 2030. In the first four months of 2026, enterprises in the Guangzhou Customs area exported movable houses worth 1.4 billion yuan, a year-on-year increase of 38.1%; in the same period, the Shenzhen port exported movable houses worth 1.68 billion yuan, a year-on-year increase of 19.6%.
