Light steel structure and heavy steel structure

Light steel structure and heavy steel structure are two different types of building structures, they are different in design, material and use, C-type, Z-type cold-formed thin-wall steel purlins and wall beams, light steel structure is mainly used in the load-bearing construction that does not accept large loads. Selection of light H-shaped steel, welded or rolled, variable section or equal section, made of portal steel frame support. The low and multi-storey prefabricated steel structure housing system is made of pressed steel plate or light sandwich plate as roof and wall enclosure structure, and the connecting parts and sealing materials such as high-strength bolts, general bolts and self-tapping screws are assembled. Earthquake resistance: The roofs of low-rise villas are mostly slope roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel components.

First of all, let's look at the light steel structure. Light steel structures are commonly used in a variety of light construction projects, such as roofs and walls of residential, commercial and industrial buildings. The materials used in this type of structure are mainly steel, including H-shaped steel, C-shaped steel and square tubes. Due to its light weight and high strength, lightweight steel structures can effectively reduce the overall weight of a building, thereby saving base costs and reducing environmental impact. In addition, the lightweight steel structure is flexible in design and can be customized according to needs, making it ideal for a variety of complex architectural designs.

Light steel structure after the completion of the tectonic plate and gypsum board, the formation of a very strong plate and rib structure system This structure system has a stronger ability to resist seismic and horizontal load, suitable for seismic intensity of more than 8 degrees in the area. The structure of the light steel structure of the special-shaped steel mill is 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 helps to prevent the influence of rust in the construction and use of the steel plate, and increases the service life of the light steel component. The structural life can be up to one hundred years, and many factories are made of such steel structure materials

In contrast, heavy steel structures are mainly used for large construction projects, such as Bridges, stadiums, airport terminals and so on. This type of structure uses materials that are stronger and more durable, including steel plates, steel pipes and reinforced concrete. Heavy steel structures have extremely high load carrying capacity and can withstand large amounts of weight and pressure, making them ideal for supporting large buildings. In addition, the heavy steel structure is structurally stable and can resist natural disasters such as wind and earthquake, so it also has advantages in terms of safety.

Welded joints, bolts or rivets are generally selected between the components or components of the heavy steel structure of the special-shaped steel mill. Because of its light weight, H-shaped steel structure room, double-layer structure room, light steel structure is mainly composed of beam steel, steel columns, steel trusses and other components made of steel and steel plates. And the construction is simple, widely used in large factories, venues, super high-rise and other fields. Light weight, good overall stiffness and strong deformation ability, so it is especially suitable for creating large-span and ultra-high and super-heavy buildings; Greatly improve its yield point strength; In addition, new forms of steel are rolled.

For example, the H-shaped steel of special-shaped steel mills, also known as wide flange steel, and T-shaped steel and molded steel plates, are used to the needs of large-span structures and super high-rise construction. In addition, there is a non-thermal bridge light steel structure system, building itself is not energy-saving. This skill uses clever special connectors to deal with the problem of hot and cold Bridges built. The small truss structure allows cables and water pipes to pass through the wall, which is convenient for construction and decoration. Good acceptance of dynamic load, short construction period; It has a high level of industrialization and can carry out specialized production with a high level of mechanization.

In general, light steel structures and heavy steel structures have their own characteristics and application ranges. When choosing which type of structure to use, it is necessary to take into account the specific architectural design needs, budgetary constraints and environmental conditions. Whether light or heavy, steel structures are an indispensable part of modern construction projects.
