One is shock resistance. Most of the roofs of galvanized steel factory buildings are sloping roofs, so the roof structure basically adopts a triangular roof truss system made of cold-formed steel members. After the light steel members are sealed with structural plates and gypsum boards, they form a very strong The "slab-rib structure system" has a stronger ability to resist earthquakes and horizontal loads, and is suitable for areas with a seismic intensity of 8 degrees or more. The second is wind resistance. The galvanized steel warehouse building is light in weight, high in strength, good in overall rigidity and strong in deformation ability. The self-weight of the building is only one-fifth of the brick-concrete structure, and it can resist a hurricane of 70 meters per second, so that life and property can be effectively protected. The third is durability. The galvanized steel factory buildings are all composed of cold-formed thin-walled steel components. The steel frames are made of super anti-corrosion high-strength cold-rolled galvanized sheets, which can effectively avoid the influence of corrosion of steel sheets during construction and use, and increase the service life of light steel components. The structural life can reach 100 years. The fourth is thermal insulation. The thermal insulation material used is mainly polyurethane thermal insulation board, which has a good thermal insulation effect. Using the insulation board on the outer wall can effectively avoid the "cold bridge" phenomenon of the wall and achieve a better insulation effect. The thermal resistance of PU polyurethane insulation board with a thickness of about 35mm can be equivalent to a brick wall with a thickness of 1m. The fifth is sound insulation. The sound insulation effect is an important index to evaluate the residence. The windows installed in the light steel system are all made of hollow glass, which has a good sound insulation effect, and the sound insulation can reach more than 40 decibels; 60 decibels. The sixth is health. Dry construction can reduce the pollution caused by waste to the environment. The steel structure materials of the house can be 100% recycled, and most of the other supporting materials can also be recycled, which is in line with the current environmental protection awareness; all materials are green building materials, which meet the requirements of the ecological environment and are beneficial to health . Seven is comfort. The light steel wall adopts a high-efficiency energy-saving system, which has a breathing function and can adjust the dry humidity of the indoor air; the roof has a ventilation function, which can form a flowing air space above the interior of the house to ensure the ventilation and heat dissipation requirements of the roof. Eight is fast. All dry construction, not affected by environmental seasons. For a building of about 300 square meters, only 5 workers and 30 working days can complete the whole process from foundation to decoration. Nine is environmental protection. Materials can be 100% recycled, truly green and pollution-free. Ten is energy saving. All adopt high-efficiency and energy-saving polyurethane thermal insulation composite board walls, which have good thermal insulation, heat insulation and sound insulation effects, and can reach 50% energy-saving standards.
