We require skilled technical workers: brick-and-concrete contractors are easily found in rural areas, as every village has a few masons. However, constructing a light steel villa is different; it necessitates hiring a specialized light steel construction team, which can be quite a hassle in rural settings. If you wish to inspect the construction team's past building projects on-site, that's an added challenge.

The cost is slightly higher than traditional brick-and-mortar construction: Although prices have dropped significantly, lightweight steel houses are still more expensive than brick-and-mortar structures. They require regular maintenance and inspection. The corrosion resistance of steel is much poorer than that of the red bricks and concrete used in brick-and-mortar buildings. How do calcium silicate boards and square steel combine? The lifespan of square steel is 8 years. Why 8 years? Consider what a small screw is left after eight years of rust and corrosion. Skyscrapers in cities use H-shaped steel, and only with proper rust prevention and waterproofing can they last over a century. The service life of ordinary lightweight steel houses is far less than that of brick-and-mortar buildings.

Insufficient Soundproofing in Light-Gauge Steel Houses: These structures have thin walls and materials that do not effectively block noise. Those who have built light-gauge steel houses have experienced this firsthand—walking on the upper floor is easily heard by those below, and the entire house shakes with the sound of a washing machine, feeling like being bombarded by explosions.

Unless additional soundproofing is done during the renovation, which would significantly increase the cost.

Poor fire resistance: Wall materials are highly flammable, and lightweight steel studs are immediately destroyed after exposure to a fire, necessitating a complete rebuild of the house.

Not suitable for water immersion or humidity: The southern region, with abundant rainfall during spring and summer, is prone to flooding in low-lying areas, often experiencing waterlogging. Lightweight steel houses naturally absorb water, and their steel frames are prone to rusting after being submerged. For the humid and rainy south, lightweight steel houses are indeed not the ideal choice. This is why lightweight steel villas are flourishing in arid provinces like Gansu and Hebei, while few are built in provinces like Sichuan and Chongqing. Rural folks are smart about building homes; they're not easily swayed by mere promotional campaigns.

Insulation

Light steel houses have thin walls and the materials themselves are not insulating, making them extremely cold during the winter in the vast northeastern regions of China. Additionally, in areas like Xinjiang with significant diurnal temperature differences, the continuous alternation of cold and hot temperatures due to large temperature variations can only withstand the light steel framing for a few years. Currently, there is no unified standard, leading to inconsistent quality and making it difficult to resolve quality disputes; there is no place to seek justice. Light steel houses heavily rely on industrialized accessories, but the entire industry is still incomplete.
