1. The exposed roof and wall are mainly made of light steel keel, and the corrosion resistance in natural environment is not as good as expected. Generally speaking, the shelf life of roofs and walls is only three years, and they may need to be replaced every 3-5 years, so the extra cost is very large.
2. The assembly of light steel structure needs skilled workers to install, and the cost increases a lot. It relies heavily on industrial support, such as prefabricated wallboard, roof panel, wall filling thermal insulation materials, fireproof materials and other processes need to be prepared in advance.
3. Compared with traditional villas, the cost of light steel villas is much higher. The project cost per square meter is about1500-2,500 yuan, which requires regular maintenance and a sum of money. Light steel villa is a new type of building, which is different from traditional buildings and must be operated by skilled construction teams.
data analysis
1. structural members: all structural members are made of high-strength galvanized steel to ensure the service life of the house. All structural members are cold-pressed by factory precision machinery assembly line, and the dimensional accuracy is millimeter, which is incomparable to other structures.
2. Roofing system: The roof truss is assembled by various light steel members, generally including triangular roof truss and T-shaped roof truss, which can easily and flexibly realize various complex roof shapes. The roof is generally made of colored asphalt shingles, which have good waterproof performance and outstanding beauty and quality.
