Which is more affordable, light steel villa or reinforced building?

In recent years, the construction of light steel villa is very popular, which is not only affordable, but also fast in construction, with little air pollution and noise, so it is worth choosing.

Compared with the traditional residence, the light steel villa has a fast construction speed, which will not affect the nearby residents and is conducive to civilized construction. It is an environment-friendly sustainable development product with light weight and good seismic performance. Compared with brick-concrete residence, light-steel villa can avoid the waste of resources caused by burning bricks with soil, and the wall thickness is small, which can increase the effective use area compared with brick-concrete structure.

However, as a steel member, it can withstand high temperatures below 250 degrees Celsius, but it is not fire-resistant. The thermal conductivity of steel is much higher than that of reinforced concrete, and the mechanical properties of steel have some unique changes at high temperature. The threat of fire to steel structure is much higher than that of reinforced concrete structure. Therefore, special attention should be paid to building fire prevention and structural fire resistance design. For fire prevention of light steel structures, fire-resistant and weather-resistant steel should be preferred when conditions permit.

Steel is easy to corrode, especially the steel used in light steel building is thin rod type. Once corroded, it will seriously reduce the bearing capacity of the structure and shorten the service life. Steel rusts easily in air or humid environment. This is mainly due to the oxidation of iron atoms on the surface of steel and air to form loose oxide rust, especially when the air contains acid, alkali and salt media. Corrosion not only causes uneven corrosion on the surface of steel structure, but also causes stress concentration due to local corrosion, which promotes the early failure of steel structure.

Therefore, effective corrosion protection should be carried out in the design of steel structure to ensure the service life of steel structure. It is very necessary for the steel structure materials of light steel buildings to be carefully and thoroughly derusted before use, and then the surface of steel structure members is coated with antirust paint grease for protection.
