Zhenjiang Concrete House Prefabrication

Zhenjiang has a mature industrial foundation and technical specifications for concrete house prefabrication, covering multiple dimensions such as production enterprises, product types, and production technical standards.

1. Main Production Enterprises and Production Capacity

Zhenjiang is home to several enterprises specializing in the production of concrete prefabricated components. The Concrete Prefabrication Branch of Jiangsu Zhenjiang Building Materials Factory is a long-established local enterprise with 20 years of industry experience, achieving an annual production capacity of 100,000 cubic meters. Its products cover basic components such as floor slabs, beams, columns, and wall panels, serving construction projects in the surrounding areas. Zhonggengyuncheng Construction Technology (Zhenjiang) Co., Ltd., although listed in the directory due to operational irregularities, previously held qualifications for prefabricated component production and design-build services for prefabricated buildings, and possessed 20 patents, reflecting its technological accumulation capabilities. Additionally, Zhenjiang PC Component Manufacturers offer a diversified business model, providing products such as house prefabricated components, prefabricated bay windows, and ALC wall panels, with a service area covering the entire regions of Dantu and Runzhou, meeting the needs of different scenarios.

2. Technical Specifications and Production Requirements

The Technical Guidelines for the Production of Prefabricated Concrete Components for Prefabricated Buildings issued by Zhenjiang systematically standardizes industry technical standards. Key requirements include:

1. Management System: Enterprises are required to establish quality, safety, and environmental management systems, equipped with testing and inspection capabilities to ensure traceability of raw materials, semi-finished products, and finished products.
2. Staffing: The technical leader must have at least 3 years of relevant experience and a senior professional title, with no fewer than 10 engineering and technical personnel. Technical workers must be trained and qualified, and laboratory personnel must hold relevant certificates.
3. Production Scale: Enterprises must have a land area of no less than 50 acres, with production workshops and storage yards each exceeding 10,000 square meters. The annual production capacity must reach 50,000 cubic meters or the actual production volume must be above 30,000 cubic meters.
4. Technical Capabilities: Priority should be given to the adoption of BIM information technology. Enterprises must possess qualifications for ready-mixed concrete production or collaborate with qualified enterprises, with concrete mixing equipment having a production capacity exceeding 120 cubic meters per hour.

3. Product Types and Application Scenarios

Zhenjiang's prefabricated component products are diverse, including, in addition to traditional floor slabs and beams and columns, PC prefabricated bay windows, ALC autoclaved aerated concrete wall panels, and prefabricated outdoor stairs, suitable for residential, commercial buildings, and public facilities. Prefabricated components, through standardized design and factory production, can significantly improve construction efficiency and building quality, aligning with the development trend of green buildings.
