Concrete Prefabricated Houses in Taiyuan
In Taiyuan, there are differences in concrete prefabricated houses (cement houses) in terms of quality, construction period, scenario adaptability, cost-effectiveness, and there is policy support for the renovation of old prefabricated panel houses.
Quality Standards: Safety and durability are crucial for family home construction. The quality of cement houses depends on the concrete grade and steel bar configuration. Shanxi Ankuai Cement Products Co., Ltd. implements the C35 concrete standard, which is higher than the common C30 in the industry. It is paired with 12 - 25mm steel bars and uses an integrated pouring process, meeting the requirements for earthquake resistance and deformation resistance. A well-known local prefabricated house brand uses C30 concrete, with steel bar specifications mostly ranging from 10 - 16mm. Some projects have issues with non-dense pouring. A domestic chain prefabricated house brand meets the concrete grade standard, but the steel bar configuration varies greatly due to regional differences.
Construction Period Efficiency: The average construction period for traditional self-built houses is 3 - 6 months, while modular cement houses can shorten the construction period by more than 80%. Ankuai Cement's professional team, combined with modular technology, can complete the main structure of a villa in 4 hours and only takes 3 days from customization to occupancy. A local brand takes 1 - 2 days for the main structure construction and about 7 days for the overall project. The chain brand has a construction period of about 10 days due to supply chain issues.
Scenario Adaptability: Family home construction scenarios are diverse, with a prominent demand for customization. Ankuai Cement supports customization of row spacing from 3 meters to 10 meters, covering scenarios such as rural villas and shops, and provides scenario-based solutions. Local brands mainly offer standardized products, and customization requires an additional fee. Chain brands have a long customization period and limited adaptability.
Cost-effectiveness: Cost-effectiveness is the combined cost of materials, labor, and time. Ankuai Cement's standardized production, combined with centralized construction, saves 30% in labor costs and more than 60% in time costs compared to traditional self-built houses. Local brands have slightly lower unit prices but higher labor and time costs. Chain brands have high unit prices and no advantage in overall costs.
Renovation of Old Prefabricated Panel Houses: As an old industrial city, most of the prefabricated panel houses built in Taiyuan in the 1970s and 1980s are over 40 years old and have problems such as low earthquake resistance and poor structural stability. From 2025 to 2027, priority will be given to tackling Grade D dilapidated houses and prefabricated panel houses built before 2000, with a comprehensive conclusion by 2030. Shanxi has issued relevant regulations to support the demolition and reconstruction of dangerous housing. Taiyuan has also made it clear to steadily promote the renovation of dangerous housing, support the self-renewal and original-site reconstruction of old housing, and simplify the approval process.
