Prefabricated Concrete House
Prefabricated concrete houses have characteristics such as rapid assembly, affordability, sturdy structure, and a long warranty period, but they also have limitations in terms of high costs for customizing shapes.
Extremely Fast Assembly Speed: Prefabricated concrete houses have significant advantages in assembly. The main structure of a set of concrete "prefabricated houses" can be completed through hoisting in about four hours. For example, the main structure of a 200-square-meter villa can be finished in 4 hours, saving about 90% of the time compared to traditional construction methods. This rapid assembly feature greatly shortens the housing construction cycle, enabling faster satisfaction of residential needs, especially suitable for scenarios such as emergency resettlement.
Relatively Affordable Prices: In terms of price, prefabricated concrete houses have a clear advantage. The price per square meter is around 300 yuan. The main structure of a 200-square-meter house only costs 110,000 yuan, and a 100-square-meter house can be built for 100,000 - 120,000 yuan, which is 30% cheaper than brick-and-concrete structures. The relatively low price makes housing construction more affordable for more people, providing a more economical option for housing construction.
Sturdy and Durable Structure: From the perspective of structural materials, it is a full-house reinforced concrete structure, using C35 concrete and thickened steel bar frames, with a self-weight of hundreds of tons. This structure gives the house strong disaster resistance capabilities. It has been tested to withstand typhoons of magnitude 12 and earthquakes of magnitude 8. During the Jishishan earthquake in Gansu, 2,000 resettlement houses were built in 72 hours, and in simulation tests, the houses only shifted by 3 centimeters, fully demonstrating their structural stability and reliability.
Long Warranty Period: Prefabricated concrete houses also come with warranty guarantees. Some responsible persons have stated a 70-year warranty. The long warranty period gives consumers more peace of mind when using them, reducing worries.
High Costs for Customizing Shapes: However, prefabricated concrete houses also have some limitations. Their shapes are relatively fixed and difficult to make large-scale modifications to. If special shapes such as rounded balconies are desired, an additional 20% customization fee is required, which to some extent increases construction costs and design difficulties.
