How many years can the light steel house be used?

For houses, a problem that many people are concerned about is the lifespan of houses. The lifespan of houses in a country directly determines their capital investment in real estate. Breaking through materials and construction methods to improve the lifespan of houses is also an inevitable trend in residential development. The light steel house is a new type of house structure, which is easy to construct and the raw materials can be recycled and reused, and the service life of the light steel house is also better than that of the traditional brick-concrete structure. Through the investigation, it is concluded that the building life in my country is short, only half of the design life on average. The main reason is that the quality of the building is not good, but it has to be retired early due to various reasons. Poor performance is the internal cause of the short life cycle of residential buildings in my country, including small area and difficulty in renovation. The main body of the light steel house is made of light steel, the usable area is increased, and the materials for later demolition and reconstruction can be recycled. Survey on the service life of foreign houses In European countries, there are many old houses with more than 100 years. Many old houses are marked with striking Arabic numerals in prominent positions to mark the construction years, indicating that the builders at that time were full of confidence that they could be durable and passed on from generation to generation. The short-lived phenomenon of residences, especially the demolition of a large number of buildings that are in their designed service life, does not conform to the sustainable scientific development concept: the disappearance of value and the inability to make the best use of everything is a huge loss of building resources and social wealth. Light steel structure houses can prolong the life of Chinese houses The main materials of light steel structure houses are C-type thin-walled high-strength steel as a light steel grid structure connected by connectors, which can withstand and transmit loads. The light steel structure system has the comprehensive advantages of light weight, factory production, rapid on-site assembly, short construction period, good seismic performance, can reduce the cost of the entire transportation and construction costs, and less environmental pollution. Compared with reinforced concrete structures, It has the unique advantages of 'beauty, atmosphere, and light overall load', and the use of light steel structures in China has been greatly promoted in the field of construction engineering.
