Guangzhou Housing Cement Prefabricated Panels
The following is information about cement prefabricated panels for housing in Guangzhou:
Regulatory Provisions
The Guangzhou Housing and Urban-Rural Development Bureau has revised and merged the 'Regulations on the Management of the Ready-Mixed Concrete and Concrete Prefabricated Component Industry in Guangzhou' (GZ Construction Regulation No. [2020] 24) and the 'Regulations on the Management of Ready-Mixed Mortar in Guangzhou' (GZ Construction Regulation No. [2020] 31) in accordance with documents such as the 'Regulations on the Development and Application of Bulk Cement and New Wall Materials in Guangdong Province' (Decree of the Guangdong Provincial People's Government No. 309). The revised regulation is named the 'Regulations on the Management of Ready-Mixed Concrete, Ready-Mixed Mortar, and Concrete Prefabricated Components in Guangzhou'. This regulation provides clear norms and guidance for the production and use of cement prefabricated panels in the Guangzhou area, helping to ensure building quality and safety and promoting the healthy development of the construction industry.
Application Scenarios
The prefabricated panel housing construction form originated in the early 20th century. Most residential buildings constructed in China before 1985 adopted prefabricated panel structures. With the continuous progress of construction technology, cast-in-place concrete and prefabricated buildings have gradually replaced traditional prefabricated panel houses. However, since the implementation of the old community renovation policy in China in 2022, the main approach for prefabricated panel houses has been repair and renovation, and only buildings that meet the criteria for dilapidated houses are demolished. Currently, there are some issues with the existing prefabricated panel houses in Guangzhou. For example, they have weak earthquake resistance. In the event of natural disasters such as earthquakes, they may not be able to effectively withstand vibrations, posing a threat to the safety of residents' lives and property. They also have poor sound insulation and thermal insulation performance, which affects the living comfort of residents. Their service life is about 30 - 50 years, and as time goes on, the building structure may experience aging and damage. Nevertheless, in some southern regions, including Guangzhou, cement prefabricated panels are still used for house construction.
Manufacturers and Products
Guangzhou has numerous prefabricated panel manufacturers, such as Yuheng Building Materials and Guangzhou Panyu Rongcheng Jianji Cement Products Factory. These manufacturers produce a wide variety of products, including 75045070 cement prefabricated panel reinforced concrete drainage ditch cover plates, cement cover plates, Jianji cement pipe drainage ditch cover plates, multi-hole ditch cover plates, and cement prefabricated panels. The prices of these products range from a few yuan to several hundred yuan, and the specific price is influenced by factors such as product specifications, materials, and quality.
