Prefabricated Houses in Lanzhou

The prefabricated houses in Lanzhou mainly include two types: prefabricated composite floor slab houses and light steel villa houses.

Prefabricated Composite Floor Slab Houses

Prefabricated composite floor slab houses are widely used in construction projects in Lanzhou, covering a variety of projects such as residential and commercial buildings. Their core advantages are reflected in three aspects: Quality Control: Prefabricated composite floor slabs are produced in factories through standardized processes, significantly reducing on-site construction errors and ensuring uniform and stable floor slab quality. For example, factory production can avoid issues such as thickness deviations or uneven strength caused by manual operations in traditional cast-in-place floor slabs. Fast Construction: Compared to traditional cast-in-place floor slabs, prefabricated composite floor slabs can shorten the construction period by approximately 30%. The construction process is divided into two steps: first, the prefabricated base plates are produced in the factory and transported to the site for assembly, and then the upper concrete layer is poured to complete the connection. This “assembly + pouring” model greatly reduces on-site formwork erection and concrete curing time, making it particularly suitable for projects with tight deadlines. Environmental Protection and Energy Efficiency: Prefabricated composite floor slabs reduce on-site wet operations (such as concrete mixing and pouring), thereby lowering construction waste and dust pollution, aligning with the development trend of green buildings. For example, traditional cast-in-place floor slab construction may generate a large amount of waste formwork and concrete residue, while prefabricated composite floor slabs reduce such waste through factory production.

The types of projects they are suitable for include:

• High-rise Residential Projects: Multi-story buildings in Lanzhou generally adopt frame structures, and prefabricated composite floor slabs can reduce on-site formwork erection time and accelerate construction progress.
• Municipal Public Buildings: For projects with strict deadlines, such as schools and hospitals, composite floor slabs can shorten the concrete curing cycle and ensure timely project delivery.
• Prefabricated Building Pilot Projects: These align with Lanzhou's 14th Five-Year Plan for the development of prefabricated buildings, allowing for policy subsidies and promoting the transformation of the construction industry towards industrialization.

Light Steel Villa Houses

The market for light steel villa houses in Lanzhou is supplied by multiple companies, including Gansu Zhongnanshan Prefabricated Building Technology Co., Ltd. and Shijiazhuang Xuanli Integrated Housing Co., Ltd. Their price range is from 680.00 yuan per square meter to 1505.00 yuan per square meter, with different brands and models offering differentiated features:

• Moisture and Water Resistance: Some products adopt special coatings or sealed designs to effectively resist humid environments and extend the lifespan of the houses.
• Aesthetic Design: A variety of styles, such as simple and elegant, are available to meet personalized needs.
• Sturdy and Aesthetic: The combination of light steel structures and decorative materials ensures both structural strength and enhanced appearance.
• Good Earthquake Resistance: Light steel materials have good ductility and toughness, enabling them to absorb seismic energy and making them suitable for earthquake-prone areas.

Light steel villa houses have a relatively short construction period, and their materials can be recycled, further demonstrating their environmental advantages.
