Introduction
Structural Steel

Structural steel, also known as construction steel, refers to the steel suitable for the construction of buildings and Bridges and other engineering building structures. This steel has excellent mechanical properties and good weldability, and the machinability is also very good.
It occupies a large proportion in the amount of steel, mainly used in the manufacture of building components and bridge structural parts, such as beams, columns, plates, load-bearing walls, Bridges, iron towers and so on. In addition, it is also widely used in the manufacture of industrial plants, high-rise civil buildings and public facilities, such as trains, automobiles, ships, tractors and large agricultural machinery.

Product Application
Construction field
The application of structural steel tube in the construction field is mainly reflected in high-rise buildings, industrial plants, commercial buildings, stadiums, exhibition halls and so on. It is mainly used as a building frame, wall support and other components, can withstand large loads, while the weight is relatively light, making the building more stable and reliable.
Bridge field
Structural steel also plays an important role in bridge engineering, including road Bridges, railway Bridges, footbridges, cable-stayed Bridges, suspension Bridges, etc. As a public facility for carrying vehicles and pedestrians, bridge has extremely high requirements for materials. It has become an important material for bridge construction because of its high strength, good rigidity, light weight and strong material corrosion resistance.
Machinery manufacturing and energy
In the field of machinery manufacturing, structural steel plate is widely used in various machine tools, presses, industrial furnaces, rolling machines, cranes, compressors, transmission equipment and so on. In addition, in the field of energy, such as wind turbine blades, hydraulic crane support and other aspects are also widely used.
Transportation
In vehicle manufacturing and road construction, it also plays an important role. It is used to manufacture key components of vehicles such as cars, trains, subways, and light rail, as well as related facilities such as road guardrails and highway suspension Bridges.

Feature
Advantageous Features
Mechanical properties
Strength: Structural steel has high tensile strength and yield strength, and can withstand large external forces without breaking or significant deformation.
Plasticity: This steel has good plasticity and can undergo a certain plastic deformation under the action of external forces without destroying its integrity.
Toughness: It has high toughness, that is, it can absorb more energy under the impact load without brittle fracture.
Hardness: The hardness of structural steel is moderate, easy to process and has a certain wear resistance.
Physical properties
Density: It has a relatively high density, which makes it more stable when subjected to external forces such as gravity.
Thermal conductivity: Its thermal conductivity is good, which is conducive to the transfer and heat dissipation of heat, thus ensuring that the structure can remain stable when the temperature changes.
Magnetic: It has a certain magnetism, can be applied to the need for magnetic occasions.
Chemical properties
Corrosion resistance: This steel has a certain corrosion resistance under general environmental conditions, but it is easy to rust in special environments (such as high humidity and high salt environment), so it needs anti-corrosion treatment.
Weldability: It has good weldability, easy to connect and repair in the project.
Process performance
Machinability: It is easy to cut, drill, bend and other processing operations to facilitate the manufacture of various shapes and sizes of components.
Heat treatment: Structural steel can improve its structure and properties through heat treatment processes, such as quenching, tempering, etc.
