Nantong Prefabricated Concrete House
Nantong's prefabricated concrete houses have seen certain developments in quality supervision, component production, and product supply, but there are also some quality issues.
Quality Supervision Situation: The Nantong Construction Engineering Quality Supervision Station conducted a special sampling inspection of prefabricated assembled concrete structures in the urban area. The results showed that the overall quality was under control. However, some projects revealed quality issues. For example, the sleeve grouting was not dense enough, which might affect the connection strength between components and the overall structural stability. The reserved length of steel bars was insufficient and did not meet the requirements of the design documents, which would have an adverse impact on the structural bearing capacity and seismic performance. These issues reflect that the quality control in some links during the construction of prefabricated concrete houses still needs to be strengthened.
Component Production Situation: Nantong Huanyang New Building Materials Co., Ltd. produces a wide variety of prefabricated assembled concrete components, including beams, wall panels, stairs, columns, composite slabs, air-conditioning panels, and balconies. It has obtained registration and publicity, with the publicity period from May 7, 2025, to May 14, 2025, and the registration certificate valid from May 15, 2025, to May 14, 2026. This indicates that the company has a certain scale and capability in the production of prefabricated concrete components, and its products have been recognized by relevant departments. However, during the sampling inspection, Nantong Huanyang Building Materials Co., Ltd. (which may be related to Nantong Huanyang New Building Materials Co., Ltd.) had insufficient reserved lengths of the upper steel bars in multiple sleeves, not meeting the requirements of the design documents. This reflects that the company may have issues with lax quality control during the production process and needs to further strengthen production management and quality inspection.
Product Supply Situation: There are 133 pieces of product information related to prefabricated cement panel houses in Nantong, with an update time of November 23, 2024. This shows that Nantong has a certain market supply of prefabricated cement panel house products and can meet a certain amount of market demand. However, the specific quality and performance of the products still require further understanding of their detailed information and user feedback.
