Light steel villas are popular recently. What advantages does it have over other designs?

Light steel villa has become the darling of villa market because of its lightness, fast construction speed and convenient construction. Light steel villas are in fashion. Light steel villa has many advantages.

First, a layer of thermal insulation material is pasted on the outer side of the light steel villa wall, which effectively blocks the thermal bridge from the wall column to the outer wall panel and also has a good thermal insulation effect. Its disadvantage is that the production technology of related supporting materials is backward, and it needs to be purchased from abroad, with high cost. In terms of cost, it is relatively low compared with other building materials, but its weaknesses are also obvious. Its seismic capacity is relatively low. A slightly larger earthquake will destroy them all. In addition, the construction period is long, the service life is short, the thermal insulation effect is poor, and the cost of building materials is also high. The cost is high, and it needs regular maintenance, which is more troublesome. The walls of light steel houses are thin and sound-proof. The fire protection performance is very poor.

Second, it is not resistant to moisture. The quality of light steel products on the market is uneven, and now the whole industry is not perfect. First of all, to build a light steel villa, we need to find a special engineering team, which is very troublesome in rural areas. It's a little more expensive than traditional bricks and concrete. It needs regular maintenance. In brick-concrete buildings, the corrosion resistance of steel bars is far less than that of red bricks and concrete. The sound insulation effect is much worse than that of traditional brick-concrete structure.

Three, light steel building wall is thin, the material itself is not sound insulation. Anyone who has built a light steel house has this experience. When decorating, the cost is too high if it is soundproofed separately. The fire protection performance is very poor. The wall material itself is easy to catch fire, and the light steel keel is also directly discarded after the fire. No foaming, no moisture resistance. It is not suitable for construction in the rainy and humid south. The wall of light steel building is thin, and the material itself is not thermal insulation material. It will be very cold in winter in the northeast of China. At present, there is no unified national standard, the quality is uneven and the whole industry is imperfect.
