Steel structure plant mainly refers to the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundation, steel roof truss (of course, the span of the factory is relatively large, basically now are steel structure roof truss), steel roof, pay attention to the wall of steel structure can also use brick wall enclosure. Due to the increase of China's steel production, many new plants have begun to use steel structure plants, which can also be divided into light and heavy steel structure plants. Industrial and civil construction facilities made of steel are called steel structures.

Steel structure plant has the following characteristics: 1, steel structure building light weight, high strength, large span. 2, steel structure construction period is short, reduce the investment cost accordingly. 3, steel structure building fire resistance is poor, corrosion resistance, low temperature areas should not use steel structure. 4, steel structure building is easy to move, recycling pollution-free.

In terms of earthquake resistance, the roofs of low-rise villas are mostly slope roofing, so the roof structure is basically a triangular roof truss system made of cold-formed steel components. After the light steel components are sealed off the structural plates and gypsum boards, a very strong "slab frame structure system" is formed. This structural system has stronger seismic resistance and horizontal load resistance ability. Suitable for seismic intensity of more than 8 degrees in the area.

In terms of wind resistance, the steel structure has light weight, high strength, good overall rigidity and strong deformation ability. The building's self-weight is only one-fifth of the brick-concrete structure, and it can resist hurricanes of 70 meters per second, so that life and property can be effectively protected.

In terms of durability, the residential structure of light steel structure is all composed of cold-formed thin-wall steel component system, and the steel bone is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of rust in the construction and use of steel plates, and increases the service life of light steel components. The structure can last up to 100 years.

In terms of thermal insulation, the thermal insulation materials used are mainly glass fiber cotton, which has good thermal insulation effect. The thermal insulation board used for the external wall effectively avoids the phenomenon of "cold bridge" on the wall and achieves better thermal insulation effect. The thermal resistance of R15 insulation cotton about 100mm thick can be equivalent to 1m thick brick wall.

In terms of sound insulation, the sound insulation effect is an important indicator to evaluate the housing. The Windows installed in the light steel system all use insulating glass, which has good sound insulation effect and the sound insulation reaches more than 40 decibels. The wall composed of light steel keel and insulation material gypsum board has a sound insulation effect of up to 60 decibels.

In terms of health, dry operation construction, reduce the pollution caused by waste to the environment, housing steel structure materials can be 100% recycled, other supporting materials can also be mostly recycled, in line with the current environmental awareness; All materials are green building materials, meet the requirements of ecological environment, and are conducive to health.

In terms of comfort, the light steel wall adopts a high-efficiency energy-saving system, has respiratory function, and can adjust the indoor air dry humidity; The roof has a ventilation function, which can form a flowing air room above the interior of the house to ensure the ventilation and heat dissipation requirements inside the roof.

Fast, all dry work construction, not affected by environmental seasons. A building of about 300 square meters, only five workers can complete the whole process from foundation to decoration in 30 working days.

In terms of environmental protection, the material can be 100% recycled, truly green and pollution-free.

In terms of energy saving, all energy-saving walls are used, with good thermal insulation, heat insulation and sound insulation effect, which can reach 50% energy saving standards.

Advantages: 1 Wide use: can be applied to factories, warehouses, office buildings, stadiums, hangars and so on. It is suitable for single-storey large-span buildings, and can also be used to build multi-storey or high-rise buildings. 2 Simple construction, short construction period: all components are prefabricated in the factory, the site only needs to be simple assembly, thus greatly shortening the construction period, a building of 6,000 square meters, just 40 days to complete the basic installation. 3 Durable, easy to repair: The steel structure of the general computer design can resist the harsh weather, and requires simple maintenance. 4 Beautiful and practical: steel structure building lines are simple and smooth, with a modern sense. The colorful wall body panel is available in a variety of colors, and the wall can also be made of other materials, so it is more flexible. 5 Reasonable cost: steel structure building light weight, reduce the basic cost, fast construction speed
