3. Safety of light steel prefabricated buildings (fire prevention, earthquake resistance, building maintenance) <br><br>3-1 House performance comparison <br><br>Light steel structure houses have the following advantages: 9 degree earthquake resistance, 12 grade wind resistance, heat insulation, heat insulation, sound insulation, Moisture proof. <br>The process of building a house is not affected by the season, and it is dry. <br>All the building materials used are environmentally friendly materials, saving environmental resources, and its advantages are even more prominent in areas where water resources are scarce. <br>In the face of natural disasters such as earthquakes and hurricanes, life and property can be most reliably protected. <br>Traditional brick-concrete structure houses are not earthquake-resistant, easy to leak, and the building process is greatly affected by the seasons. The whole process is wet-processed. The building materials used are at the cost of destroying environmental resources and water resources. In areas where water resources are scarce, building houses is more difficult. More prominent. In the face of natural disasters such as earthquakes and hurricanes, the losses to life and property are huge. <br><br>3-1 House safety and maintenance <br><br>The keel of the light steel house is a high-strength aluminum-galvanized steel plate G550 AZ150. The surface structure is a dense quaternary crystal composed of aluminum-iron-phosphorus-zinc. The aluminum-plated zinc keel is exposed to the air for a long time. There is basically no color change on the middle surface. In case of chemical corrosion, this crystal forms an effective anticorrosive protective layer on the steel plate to protect the main material of the keel from rust. The authoritative test can be used for more than 100 years. The main materials can be maintained and repaired free of charge within the warranty period. <br><br>For the masonry-concrete structure house, due to its structural decision, the later maintenance is mainly caused by the foundation sinking causing the wall to crack, fall off, and the house seepage, etc. These maintenance costs need to be paid by the owner himself, which is a lot of expenses. <br><br>In addition, 100% of the light steel keel of the main body of the light steel villa can be recycled, and more than 80% of the remaining structural plates can also be reused, and the brick and concrete structure houses are basically construction waste after demolition, and the reuse value is not high. If the life of the light steel villa is 100 years compared with the brick and concrete 50 years, the cost performance of the light steel villa is even higher. <br><br>I have added the security test video to the attachment, please ask the professor to open the attachment to view. <br>1.

Fire protection effect, but the interviewee did not provide a fire protection video, you can check the application of fire protection materials in the first operation, such as: asbestos tiles and fire protection materials.
