Prefabricated Panel Houses in Macheng

There are prefabricated panel houses in Macheng, with various safety levels, and there are factories related to the production and sales of prefabricated panels locally.

Situation of Prefabricated Panel Houses

The prefabricated panel houses in Macheng are generally around four to five decades old. In terms of building safety levels, according to the 'Standard for Appraisal of Dangerous Buildings' (JGJ 125 - 2016), building safety levels are divided into four grades: A, B, C, and D. Grade A buildings have no dangerous components, are structurally safe, and can be normally inhabited; Grade B buildings have minor issues with individual components, but these do not affect the main structure, and regular observation is sufficient; Grade C buildings have partial load-bearing structures that no longer meet the requirements for safe use, are considered 'partially dangerous', and can still be 'repaired'; Grade D buildings have severely damaged load-bearing structures, are in a dangerous state overall, and in principle, can only be demolished. There may be different safety levels among the prefabricated panel buildings in Macheng. For example, the prefabricated panel building in Hongyuan Community, Leqing, Wenzhou, Zhejiang, was identified as a Grade C dilapidated building in 2015. After reinforcement measures were taken, its condition deteriorated and it was upgraded to Grade D by 2025, and was ultimately demolished and rebuilt; the prefabricated panel building at No. 2 Jiqun Street, Huadu, Guangzhou, was identified as a Grade D dilapidated building in 2024, and was demolished and rebuilt after residents raised funds on their own and received government subsidies. Although these cases are not from Macheng itself, they can indirectly reflect that as time passes, prefabricated panel houses may experience changes in safety levels due to factors such as structural aging, and similar evolution from lower safety levels to higher danger levels may also occur in the prefabricated panel houses in Macheng.

Factories for Production and Sales of Prefabricated Panels

There are factories in Macheng related to the production and sales of prefabricated panels. For example, Qiwuyuan Prefabricated Factory in Zhongguanyi Town, Macheng, was established on May 7, 1998, and mainly provides the production and sales of prefabricated panels; Macheng Huangjinqiao Prefabricated Factory was established on January 18, 1998, and mainly produces prestressed hollow floor slabs and small components. The existence of these factories indicates that Macheng has a certain industrial foundation in the production and sales of prefabricated panels.
