Prefabricated Panels for New-Type Houses
Prefabricated panels for new-type houses mainly include new-type wall prefabricated panels and prefabricated components used in different forms of 'prefabricated houses', each with distinct characteristics in terms of development and pricing.
New-Type Wall Prefabricated Panels
New-type wall prefabricated panels are easy to install. They can be directly pasted onto walls without the need for cement or complex construction processes. Simply applying glue can give walls a brand-new look with perfect line connections. These panels are waterproof and fire-resistant, offering a new option for wall decoration.
Forms and Characteristics of 'Prefabricated Houses'
'Prefabricated houses' mainly come in three forms: steel structure, concrete structure, and wooden structure. Chinese companies have a comparative advantage in steel and concrete structures. Steel structures are lightweight, suitable for ocean transportation and high-rise buildings, and excel in space utilization and transportation convenience. Concrete structures are closer to traditional living experiences, highly accepted in the domestic market, and can meet people's preferences for traditional residential styles.
Development of Prefabricated Panel Houses
Prefabricated panel houses originated in the early 20th century. In China, most residential buildings constructed before 1985 adopted this structure. With the development of construction technology, cast-in-place concrete and prefabricated buildings have gradually replaced traditional prefabricated panel houses. Prefabricated buildings use modular factory-prefabricated components. For example, CMC composite modular buildings enhance earthquake resistance through steel-concrete integral pouring, reducing construction time by 30% compared to traditional methods. Since 2022, China has implemented a policy of renovating old residential areas, focusing on repairing and renovating prefabricated panel houses and only demolishing buildings that meet the criteria for dangerous houses. Existing prefabricated panel houses generally have issues such as weak earthquake resistance, poor sound and heat insulation, and a lifespan of about 30-50 years. Some regions have already initiated demolition work.
Prices of Prefabricated Panel-Related Products
The prices of prefabricated panel-related products vary widely. Custom concrete hollow panels, prestressed concrete circular hole floor slabs for construction projects, and dedicated cement prefabricated panels are priced at 24.0 yuan per 25 meters. Prefabricated floor slabs, cement-reinforced concrete catchment pit panels, trench panels, prestressed hollow slabs for house construction with a thickness of 12 centimeters are priced at 18.0 yuan. Foreign trade light steel villas, hotel steel structures, movable prefabricated houses for homestays, and prefabricated container houses from source manufacturers are priced at 90.0 yuan per 13 square meters. Prices vary significantly depending on the type and specifications of the products.
