Steel strurture is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation. So it is especially suitable for building large-span, ultra-high, and ultra-heavy buildings.
The material has good homogeneity and isotropy, and is ideal elasticity. The body is most in line with the basic assumptions of general engineering mechanics.
The material has good plasticity and toughness, can be deformed greatly, and can withstand dynamic loads well. The construction period is short. Its high degree of industrialization can carry out specialized production with a high degree of mechanization.
- High material strength and light weight.
- Steel toughness, good plasticity, uniform material, high structural reliability.
- High degree of mechanization of steel structure manufacturing and installation.
- The steel structure has good sealing performance.
- The steel structure is heat-resistant and not fire-resistant.
- Poor corrosion resistance of steel structure.
- Low carbon, energy saving, green and environmental protection, reusable.
- The demolition of steel structure buildings hardly produces construction waste, and steel can be recycled and reused.
- The steel mouth is close to a homogeneous isotropic body17. The steel structure has the characteristics of no leakage.
A structure consisting of members connected to each other with screws on both sides. The truss is composed of metal rods and generally has a triangular unit plan or space structure.
The truss rods mainly bear the radial tensile force or pressure, so the strength of the material can be flexibly used, and the material can be saved compared with the solid web beam when the span is large. , to relieve its own weight and expand bending stiffness.
The advantage of the truss is that the rods mainly bear the tensile force or pressure, can make full use of the functions of materials, save materials, and reduce the weight of the structure. Common steel trusses, concrete structure trusses, prefabricated concrete trusses, wood trusses, steel and wood trusses, and steel-cement-soil trusses.
The indoor space structure is formed by connecting multiple rods according to a certain grid pattern according to the connection points. The basic units that form the grid structure include triangular pyramids, triangular bodies, cubes, truncated quadrangular pyramids, etc., which can form triangular, quadrilateral, hexagonal, ring or any other shapes in plan view.
It has the characteristics of indoor space bearing capacity, light weight, high bending rigidity, and good earthquake resistance. It can be used in sports venues, cinemas, exhibition halls, waiting halls, stadium stand canopies, hangars, double-column spherical grid structures and production workshops Roof trusses of buildings etc. The main disadvantage is that there are a large number of rods that meet in the connection point, and the manufacturing and assembly are more complicated than the planar structure.
The cable-membrane structure system started from the outdoor tents (housing buildings composed of support poles, ropes and furs) that humans lived in in ancient times. After the 1970s in the 20th century, the birth of membrane materials with high strength, moisture resistance, light transmission, smooth surface, easy cleaning, and aging resistance, coupled with the rapid development of engineering computing science and rationality, the cable-membrane engineering building structure system started again. Now it has been used in many commercial buildings in various areas such as seaside tourism, exhibitions, literature and art, sports, etc.
Light steel structure structure is a young and vigorous steel structure system, which has been widely used in general industry and agriculture, commercial services, and service-oriented engineering buildings, such as office buildings, single-family villas, warehouses, sports venues, games and entertainment, and vacation tourism. Engineering construction and low and high-rise residential and construction industries.
Light steel structure is also a relatively ambiguous term, and there are generally two main understandings. The light steel structure made of 4 angle iron is mainly used to manufacture small structures in the era of lack of building steel. It is not recommended to use concrete structure structure to manufacture small structures. Most of them are not used. Most tend to get rid of.
For structures with relatively large heights and relatively small cross-sections, horizontal loads (especially wind loads) are an important basis for structural customization. According to its structure, it can be divided into independent vertical structure and pull rope mast structure, so the tower structure is also called tower mast structure.
With the development of industrial production technology, various types of towering structures appear. In 1889, the Paris Eiffel Tower was built for the Paris Exhibition, with an absolute height of 300 meters. After 1921, wireless communication antennas and TV antennas were placed on the tower, with a total height of 321 meters.
Steel crane girders, steel roof trusses and steel columns should be used for heavy-duty cranes or large-tonnage cranes or workshops with 2-3 floors of cranes and some high-temperature workshops with large spans and column distances. As well as all-steel structure.
When the span of the structure is larger, reducing the self-weight of the structure will have obvious economic effects.
High-rise structures include high-voltage transmission line towers, substation structures, radio and TV transmission towers and masts, etc. These structures mainly bear wind loads. The small section of the member reduces the wind load and thus achieves greater economic benefits.
Due to the good dynamic performance and toughness of steel, it can be used as a crane girder that directly bears a large load or a bridge crane with a large span.
Steel structures are most suitable for mobile exhibition halls and mobile houses. Steel structures are light in weight and easy to dismantle.
When bolted connections are used, they are easy to assemble and disassemble. Construction machinery must use steel structures to reduce the weight of the structure.
Due to the high strength and good airtightness of steel, high-pressure gas pipes, pipes, gas tanks and boilers are all made of steel.
The light steel structure composed of single angle steel or thin-walled steel and the portal steel frame structure have the advantages of small weight, fast construction and less steel, and have been widely used in recent years.
Transportation corridors, trestles, various pipeline supports, blast furnace and boiler frames, etc. are usually steel structures.

Before proceeding with steel structure production, design and drawing are required. designer according to building or the needs of bridges, formulate corresponding structural schemes, and draw up detailed construction drawings.
These drawings include the size, quantity, material, connection method and other information of the components.
Steel structure production requires a large amount of steel, so material procurement is required. Generally speaking, the quality and specification of steel have a crucial impact on the quality and performance of steel structures.
After the steel is purchased, it needs to be processed, including cutting, drilling, stamping and other processes, in order to components that meet the requirements are produced.
Before making the components, it is necessary to segment and number the components according to the construction drawings.
Then, process and manufacture components according to the requirements on the drawings. These components include beams, columns, bridge decks, etc.
During the manufacturing process, CNC press brake bending machines and plate shearing machines are required to achieve the required size and precision, and quality inspection is required to ensure that the size and quality of the components meet the requirements.
Wuxi Shenchong Forging Machine Co., Ltd. produces high-precision & fast press brakes and shearing machines. While ensuring quality, it can improve production speed and efficiency and enhance your competitiveness.
After the components are fabricated, the components need to be assembled. This process includes welding, screwing bolt connection etc. During assembly, quality checks are required to ensure that components strong connections and accurate dimensions.
After the components are assembled, surface treatment is required. This process includes rust removal, painting and other processes to protect the steel structure from corrosion and oxidation.
After the surface preparation is completed, it needs to be transported and installed. This process requires the use of large.
Lifting equipment, transport the components to the site, and install them. During installation, the quality checks are to be carried out to ensure the safety and stability of the steel structure.
The steel structure production process is a complex process that requires coordination and coordination of multiple links combine. Only by operating strictly in accordance with the requirements in each link can we produce high-quality steel structure.
