Steel frame multi story buildings have also taken a series of effective measures in fire prevention, sound insulation, and other aspects. In terms of fire prevention,

fireproof coating should be applied to steel structures to improve their fire resistance limit; In terms of sound insulation, high-performance sound insulation materials

are used to treat the walls, floors, etc. of the building, effectively reducing the interference of external noise on the interior of the building and creating a quiet and

comfortable environment for people.

Product Advantages

High strength and high load-bearing capacity: The steel used in the steel structure frame has extremely high strength, such as common Q345, Q460 and other types of steel, whose yield strength is much higher than traditional building materials. This enables steel frame structures to withstand enormous vertical and horizontal loads, meeting the strict requirements for structural stability in multi story buildings and effectively ensuring the safety of buildings in various complex environments.

Product Application

Shopping centers: Large shopping centers typically require open and flexible spaces, and steel frame multi story buildings perfectly meet this demand. A large-span space with no or few pillars inside, which facilitates the planning of different business areas such as clothing, catering, entertainment, etc. Like Shanghai's Zhengda Plaza, which uses a steel structure framework to achieve a multi-level and diversified commercial layout, it can accommodate numerous well-known brand stores, and is equipped with a large atrium and public activity area, attracting a large number of consumers.
