Prefabricated Concrete Houses in Gansu

In Gansu, the prefabricated concrete house industry primarily focuses on the production of prefabricated floor slabs and prefabricated cement houses, influenced by national standards, climatic characteristics, and industry supervision, forming a standardized development model.

Prefabricated Floor Slabs: Diverse Types for Different Scenarios

The production of prefabricated floor slabs in Gansu strictly adheres to national standards such as the 'Code for Design of Concrete Structures' (GB50010), with a concrete strength grade of no less than C30, and is optimized for the local climate characterized by large temperature variations and dryness. Common types include:

• Hollow Slabs: Lightweight, with good sound insulation and recognized moisture resistance, often used for residential floor slabs, especially suitable for cost-sensitive scenarios like rural self-built houses.
• Solid Slabs: With strong load-bearing capacity, suitable for large-span or high-load scenarios such as warehouses and factories, including logistics centers and industrial workshops.
• Composite Slabs: Combining the advantages of prefabricated standardization and cast-in-place integrity, enhancing structural integrity through the collaborative work of prefabricated and cast-in-place layers, often used for floor slabs in high-rise buildings.
  Additionally, manufacturers offer customized services, such as producing small floor slabs according to the needs of rural self-built houses or designing earthquake-resistant reinforced floor slabs for earthquake-prone areas to meet diverse needs.

Prefabricated Cement Houses: Concentrated Manufacturers, Convenient Procurement Channels

The prefabricated cement house industry in Gansu has formed a certain scale, with 110 related manufacturers recorded on the Baidu Ai Purchase platform as of December 9, 2024, supporting wholesale procurement. These manufacturers typically offer standardized cement house products covering various uses such as residential, office, and storage, with some enterprises also supporting modular combination designs for rapid construction and expansion.

Industry Supervision: Real-time Data Upload Ensures Quality Compliance

The Gansu Provincial Department of Housing and Urban-Rural Development has conducted special rectifications on ready-mixed concrete production enterprises through the engineering quality inspection supervision system, requiring real-time upload of inspection data. As of the end of September 2024, 321 quality inspection enterprises have been registered across the province, uploading over 883,000 pieces of data, including over 505,000 pieces of concrete compressive strength data, with不合格 (unqualified) data accounting for only 1.3‰. This supervision measure indirectly ensures the quality compliance of prefabricated components and reduces engineering risks.

Enterprise Support: Complete Technical Qualifications, Participating in Market Bidding

Taking Gansu Yuhao Concrete Engineering Co., Ltd. as an example, the company specializes in the production and sales of commercial concrete and prefabricated component processing, possessing the professional contracting qualification for ready-mixed concrete and participating in multiple bidding projects. Such enterprises, through technical accumulation and qualification certification, provide material supply, component processing, and technical support for the prefabrication of concrete houses, promoting the industry's development towards specialization and scale.
