Steel Prefabricated Housing

Steel prefabricated housing is a residential building that uses a steel structure system as its main load-bearing structure and adopts a prefabricated construction method. It has advantages such as earthquake resistance, rapid construction, and being green and low-carbon. It has been applied in projects such as affordable housing and commercial housing, with a variety of market brands and prices varying by type and specification.

Structure and Construction Method

The core structure of steel prefabricated housing is a steel structure system. Factory-prefabricated components (such as steel beams, steel columns, and floor decking) are transported to the site and quickly assembled using a prefabricated method. This construction method reduces on-site wet work, significantly shortens the construction period, and the high strength of the steel structure gives it excellent earthquake resistance, making it especially suitable for earthquake-prone areas.

Advantages and Characteristics

1. Good Earthquake Resistance: The high ductility of steel structures allows them to absorb seismic energy through deformation, reducing the risk of structural damage.
2. Rapid Construction Speed: The prefabricated process enables the main structure to be completed within a few weeks, improving efficiency by more than 50% compared to traditional concrete buildings.
3. Green and Low-Carbon: The steel recycling rate exceeds 90%, and the construction process generates low levels of dust and noise pollution, meeting sustainable development requirements.
4. High Space Utilization: The large span of steel structures eliminates the need for load-bearing walls, allowing for flexible interior layouts to meet personalized needs.
5. Recyclable Materials: After demolition, steel can be remelted and processed, reducing the generation of construction waste.

Application Cases and Brands

In China, steel structure housing has been applied in multiple projects, such as Baotou Wanjun Metropolis (affordable housing) and Hangzhou Qianjiang Century City Talent Special Housing (commercial housing), verifying its technical maturity. Mainstream brands in the market include Furui Mei, Baisheng Creative, and Wanlong, which provide one-stop services from design to installation.

Materials and Processes

In terms of materials, steel prefabricated housing commonly uses a combination of sandwich panels (for thermal insulation), steel structures (as the load-bearing main body), and concrete (for local reinforcement). Processes include welding (for fixed connections), assembly (for modular construction), and bolt connections (for easy disassembly), with bolt connections being the preferred choice for temporary buildings due to their convenient construction and strong reversibility.

Price Range

Prices vary significantly depending on the type and specification:

• Simple prefabricated glass-curtain-wall mobile board houses for construction sites: Approximately 255 yuan per square meter, suitable for short-term construction site dormitories.
• Container houses with canopies: 1,800 yuan per set (including decoration), suitable for rapidly deployed temporary office or living scenarios.
• High-end customized steel structure residences: Prices can reach several thousand yuan per square meter, including fine decoration and intelligent systems.

Steel prefabricated housing, with its technological advantages and economic efficiency, is gradually expanding from temporary buildings to permanent residences, becoming an important direction in the modern construction field.
