Guangdong Steel Prefabricated House Construction

The construction of steel prefabricated houses in Guangdong adopts a modular building model, combining factory prefabrication with on-site assembly to achieve efficient, eco-friendly, and durable construction goals.

Construction Method

The core of Guangdong's steel prefabricated houses is modular construction: buildings are divided into independent modules (such as ceilings, floors, plumbing and electrical systems, etc.), which are prefabricated on factory assembly lines and then transported to the site for assembly. For example, the Shenzhen affordable housing project assembled five residential buildings nearly 100 meters high using 6,028 concrete modules, with a 70-square-meter unit requiring only two and a half modules. This “building block” approach significantly reduces on-site wet work and enables standardized production.

Construction Advantages

1. Short Construction Period: Compared to traditional methods, the construction cycle is reduced by over 60%. The Shenzhen affordable housing project's timeline was shortened from 2.5-3 years to 1 year, while the Guangzhou steel structure residential project's timeline was compressed from 2 years to 14 months, saving 30% of time.
2. Quality Control: In the factory, millimeter-level precision is used to control the position of steel bars and module errors, ensuring structural stability. For example, the Guangzhou project improved building quality by reducing human errors through standardized production.
3. Energy Efficiency and Environmental Protection: On-site noise and dust are reduced, construction waste is cut by 80% (as seen in the Guangzhou project), and steel utilization exceeds 95%. The Shenzhen project further reduced disturbances by adopting cast-in-place connection technology.
4. Easy Maintenance: Prefabricated houses have a lifespan of 100 years, ten times that of ordinary temporary buildings, reducing long-term maintenance costs. For example, the scenic area shop project completed the construction of six shops in three days, demonstrating significant long-term operational benefits.

Application Scenarios

This technology is suitable for rural self-built houses, cultural tourism homestays, new rural resettlement housing, small office buildings, and elderly care residences. For example, the scenic area shop project achieved revenue exceeding expectations by 200,000 yuan in the first month through rapid construction, demonstrating its commercial value; the Guangzhou steel structure residential project met high safety requirements with its design capable of withstanding typhoons of magnitude 12.

Typical Cases

• Shenzhen Affordable Housing Project: Assembled 6,028 modules, reducing on-site labor by 50% and shortening the construction period by over 50%.
• Guangzhou Steel Structure Residential Project: Adopted the China Construction Science and Industry system, with 80% of components produced in the factory, saving 17 million yuan in temporary relocation fees.
• Scenic Area Shop Project: Completed construction in three days, enabling rapid operation and increased revenue.

Guangdong's steel prefabricated houses, through modular technology, offer comprehensive advantages in efficiency, quality, environmental protection, and cost-effectiveness, making them an important direction in modern construction.
