Steel structures are made of steel materials. As one of the main types of building structures, this structure is mainly composed of steel beams, columns, trusses, and other profiles and steel plate components. Select rust prevention processes such as silicification, pure manganese phosphating, cleaning and drying, and galvanizing. Bolts or rivets are usually used to connect parts or components. Due to it has lightweight and simple structure, it is widely used in large workshops, facilities, high-rise buildings, and other fields.
The characteristics of this type of steel are high strength, light weight, high overall stiffness, and strong resistance to deformation. Therefore, building large, very high, and very heavy buildings is particularly suitable; The material is an ideal elastic material with good homogeneity and isotropy, which is most consistent with the basic assumptions of general Applied mechanics. This material has good plasticity and strength, can undergo significant deformation, and can withstand dynamic loads well; Short working hours; Highly industrialized can specialize in production and highly mechanized.

Features:
1. This material is high-strength and lightweight
Since the density and yield strength are relatively low compared with that of concrete and wood, the steel structure has a small cross section, light weight, and easy transport and installation, and is suitable for large span, high altitude and large load structure.
2. Steel has good toughness, plasticity, homogeneous materials and high structural reliability
It has good seismic performance and can withstand effects and dynamic loads. The internal structure of iron is uniform and almost isotropic. The actual performance of the iron structure is more consistent with the theory of calculation, so the trust of the iron structure is high.
3. High level of mechanization in the production and installation of iron structures
Iron structure is easily manufactured in the factory and manufactured in the location. The iron component factory has advantages such as high precision, high production efficiency, fast installation speed, and short construction time. Iron structure is the most industrial structure.
4. Good sealed effect of steel structure
Due to the structure of fully solid iron that can be signed, there are high pressure vessels, high air stability and solid water, large-scale oil fishing, pipeline pressure, etc.

5. Heat resistant steel structure without fire resistance
At temperatures below 150℃, there may be some changes in the properties of steel. Therefore, steel structures are suitable for high temperature laboratories, but when the surface of the thermal structure is exposed to a temperature of about 150℃, insulation plates are used for protection. When the temperature drops between 300℃ and 400℃, the strength and consumption of steel molds decrease significantly. At a temperature of about 600℃, there is no strength of steel. In buildings with firepower, steel structures are protected against material degradation, which achieves better fire resistance levels.
6. Poor corrosion resistance of steel structure
Especially in humid and corrosive environments, it is prone to rusting. General iron structures require release, galvanizing or painting, and require regular maintenance. For the design of offshore and aerial platforms, special measures should be taken, such as"zinc block screen protection", to prevent damage.
7. Low carbon, energy storage, environmental protection, and reusable
The destruction of steel structures hardly generates construction waste, and steel can be reused.

Application program:
Compared with ordinary reinforced concrete structures, steel structures have the characteristics of good uniformity, high strength, fast construction speed, good seismic performance, and fast recovery speed. The strength and elasticity of steel are many times that of bricks and concrete. Under the same conditions, the weight of steel components is lighter. From the perspective of damage, steel structures have large early deformation precursors and belong to flexible single-layer structures, which can be detected in advance to avoid danger.
Steel structure construction plants have the characteristics of light weight, basic economy, few materials, low cost, short construction time, large floor area, safety and reliability, beautiful appearance, and stable structure. Steel structure construction plants are long-term industrial buildings, warehouses, cold storage, high-rise buildings, office buildings, and other multi-story residential areas; Widely used in residential and other construction industries.

Steel structure installation:
Precast of steel components:
The steel parts on the prefix and skid are installed in sequence, but the work of the dispersal equipment is related to the quality of the steel.
The distance between flame water and steel enclosed trees is greater than 200mm. The length of the closed flash must be the minimum length of the distance. The width and length of each part of the epidemic shall not be less than 300mm and 600mm.
To ease the solution and ensure the quality of the solution, do the solution on the iron tube on the ground as much as possible according to the size of the construction painting. The solution of the column should be done next to the plate, the link sign, the back and bar (light) in the column and bar as much as possible.
In addition to producing and installing prefabric parts of iron on iron machrate according to the construction design and specification, it must also be considered easily for field load and change in the installation dimension.
