What is a light gauge steel framing structure?

Light gauge steel framing structure refers to a light steel building with small load and small span, which is usually divided into thin steel plate, steel and skeleton structure. The lgs steel structural form of light steel structure is greatly influenced by the traditional European wooden frame building. It is often composed of thin-walled steel or small-section steel to form trusses to replace the wall bars, joists and rafters of wooden buildings. The combination of skeletons is generally related to the scale of the building, production method, construction conditions and transportation capacity. Common ones are:

Unit component building system: The building is assembled into a light steel structure frame by unit components such as columns, wall bars, beams, joists, purlins, rafters and roof trusses, and then the roof is laid, and wall panels, doors and windows are installed. The nodes of the frame are mostly fixed with bolts and connecting plates. In order to enhance the stability of the assembled frame, supports or adjustable cross-type tie rods are added at necessary locations. Buildings assembled with unit components are flexible to assemble and easy to transport, and can meet the needs of various building space combinations. However, the on-site construction time is longer than other installation methods.

Frame partition building system: light gauge steel framing partitions composed of thin-walled light gauge steels are used as the load-bearing skeleton structure of walls, floors and roofs to assemble the entire building. The inner and outer layers, internal insulation, heat insulation layers, doors and windows of this building can be installed during prefabrication in the factory, or they can be installed at the construction site after the skeleton is assembled. This building system is like a plate-assembled building, requiring fewer specifications and types of partitions and convenient node assembly. Since most of the work can be completed in the factory, the quality is higher and the on-site construction speed is faster.

What are light steel frames used for?

1. Residential buildings: Light gauge steel framing structures have good plasticity and sound absorption, and are suitable for villas and residential buildings below three floors.

2. Commercial buildings: For commercial buildings, short construction time and fast speed are very important considerations. Light gauge steel framing structures are a very good choice, which can save a lot of time and cost.

3. Office buildings: The application of lgs steel framing structures in office buildings has become increasingly popular. It not only has a beautiful appearance and a solid structure, but also is easy to maintain and clean, reducing the pollution of the office environment and the spread of diseases.

4. Industrial buildings: Light gauge metal framing structures also perform well in industrial buildings. They can not only adapt to various environments, but also meet different needs, thereby meeting the needs of enterprises.

Advantages of light gauge steel framing structure frame?

Earthquake resistance: Most of the roofs of low-rise villas are sloping roofs, so the roof structure basically adopts a triangular roof truss system made of cold-bent steel components. After the light steel structures components are sealed with structural plates and gypsum boards, a very strong "plate rib structure system" is formed. This structural system has stronger earthquake resistance and resistance to horizontal loads, and is suitable for areas with an earthquake intensity of 8 degrees or more.

Wind resistance: Light steel structure buildings are light in weight, high in strength, good in overall rigidity, and strong in deformation ability. The building's own weight is only one-fifth of that of a brick-concrete structure, and it can withstand a hurricane of 70 meters per second, so that life and property can be effectively protected.

Durability: The lightweight steel structures residential structure is composed entirely of cold-bent thin-walled steel component systems. The steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of rust on the steel plate during construction and use, and increases the service life of the light gauge steel components.

Health: Dry construction reduces the pollution caused by waste to the environment. The light gauge steel framing structure materials of the house can be 100% recycled, and other supporting materials can also be mostly recycled, which is in line with the current environmental awareness; all materials are green building materials, meet the requirements of the ecological environment, and are beneficial to health.

Comfort: The light steel wall adopts an efficient energy-saving system, has a breathing function, and can adjust the indoor air dryness and humidity; the roof has a ventilation function, which can form a flowing air space above the house to ensure the ventilation and heat dissipation needs inside the roof.

Environmental protection: The material of light gauge steel framing construction is 100% recyclable, truly green and pollution-free.
