Prefabricated Concrete Flat-Roof House

Prefabricated concrete flat-roof houses are a form of construction built using a factory-prefabricated and on-site assembly model, characterized by high efficiency, cost-effectiveness, and excellent performance.

Price: Prices vary by region and brand. The product price of Xinsheng Cement Products Co., Ltd. in Biyang County, Zhumadian City, Henan Province is 300.00 yuan per square meter; the product price of Xinwei Hongtu Trading Co., Ltd. in Zhuozhou City, Baoding City, Hebei Province is 260.00 yuan per square meter; the product price of Hanzhong Shengxin Prefabricated Construction Engineering Co., Ltd. in Hanzhong City, Shaanxi Province is 650.00 yuan per square meter.

Performance:

• Structural Strength: Utilizing C30-C40 grade concrete with built-in φ8-φ12 steel reinforcement mesh, the compressive strength reaches 25-30 MPa, which is 1.5 times that of traditional brick-and-mortar structures.
• Thermal Insulation and Energy Efficiency: The walls are designed with reserved slots for EPS insulation layers, which, when inserted, improve thermal insulation performance by 40%, providing significant warmth in winter and coolness in summer.
• Disaster Resistance: Modules are connected via prestressed bolts and welded steel plates to form an integrated frame, achieving a wind resistance rating of Level 10 and an earthquake resistance intensity of 7 degrees (equivalent to the destructive force of the Wenchuan earthquake).
• Durability: The houses are fire-resistant, windproof, moisture-proof, corrosion-resistant, and weather-resistant, adapting to various climatic conditions.

Construction Efficiency:

• A single 30㎡ module can be prefabricated in the factory in just 7 days. After transportation to the site, three workers with a crane can complete the installation of a single module in 4 hours, and the entire construction of a 100㎡ house takes only 2 days. Case studies in rural areas of Henan show that a villa can be built in as little as 4 hours, and an entire building can be completed in 2 days.

Cost Advantage:
Taking a 120㎡ rural self-built house as an example, the cost of a traditional brick-and-mortar structure is approximately 180,000-220,000 yuan (including labor), while the cost of the main modules of a prefabricated concrete house is only 120,000-150,000 yuan. With interior and exterior decoration, the total cost can be controlled within 200,000 yuan, representing a 30% reduction in overall costs. In rural areas of Henan, the price of prefabricated concrete houses is around 300 yuan per square meter, with the total cost of a large villa being approximately over 100,000 yuan.

Scope of Application:
These houses can be used to construct office buildings, small hotels, staff dormitories, canteens and restaurants, private garages, storage warehouses, etc. They are widely applicable to scenarios such as rural dilapidated house renovation, rural self-built housing, farm supporting housing, temporary office and accommodation for construction sites, and temporary supporting facilities for engineering projects.
