What is Steel Construction(SC)
Steel construction refer to steel structure composite components that are made of steel plates, angle steel, channel steel, I-beams, welded or hot-rolled H-beams, cold-formed or welded and connected through connectors and can withstand and transmit loads.

Steel construction refers to the process of using steel as the primary material for building structures. Steel is widely used in various types of construction, including residential, commercial, industrial, and infrastructure projects, due to its strength, durability, and versatility. Steel construction involves the use of steel beams, columns, frames, panels, and other components to create load-bearing frameworks and structural systems. This method of construction is known for producing safe, sturdy, and long-lasting buildings and is widely favored for its numerous advantages.
Application:
Mainly used in industrial plants, long-span structures, high-rise structures, multi-high-rise civil buildings, structures with high dynamic load and earthquake resistance requirements, plate and shell structures, detachable structures, light steel structures, and reinforced concrete composite structures, etc.
Advantages:
The steel component system has the comprehensive advantages of light weight, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it is more "tall, large, and light". Due to the unique advantages of development in the three aspects, steel constructions have been reasonably and widely used in the field of construction engineering around the world, especially in developed countries and regions.
Disadvantages:
1. Poor corrosion resistance
2. High heat-resistant but poor fire-resistant (loses load-bearing capacity above 600 degrees Celsius)
3. Under conditions such as low temperature, brittle fracture may occur.
Key Features
Carrying capacity
Practice shows that the greater the force, the greater the deformation of the steel construction. However, when the force is too large, the steel construction will break or undergo severe and significant plastic deformation, which will affect the normal operation of the engineering structure. In order to ensure that engineering materials and structures work normally under load, each steel construction is required to have sufficient load-bearing capacity, also known as load-bearing capacity. The load-bearing capacity is mainly measured by the sufficient strength, stiffness and stability of the steel construction.
sufficient strength
Strength refers to the ability of a steel construction to resist damage (breakage or permanent deformation). That is, the ability to work safely and reliably without yielding failure or fracture failure under load. Strength is a basic requirement that all load-bearing members must meet, and therefore is the focus of learning.
sufficient stiffness
Stiffness refers to the ability of a steel member to resist deformation. If the steel construction undergoes excessive deformation after being stressed, it will not work properly even if it is not damaged. Therefore, steel members must have sufficient stiffness, that is, stiffness failure is not allowed to occur. Stiffness issues have different requirements for different types of components. Please refer to relevant standards and specifications when applying.
stability
Stability refers to the ability of steel constructions to maintain their original balanced form (state) under the action of external forces.Loss of stability is the phenomenon that when the pressure increases to a certain extent, the steel construction suddenly changes its original balance form, which is referred to as instability. Some thin-walled constructions under pressure may also suddenly change their original balance form and become unstable. Therefore, these steel constructions should be required to have the ability to maintain their original balance form, that is, to have sufficient stability to ensure that they will not become unstable and damaged under the specified conditions of use.The instability of the pressure rod generally occurs suddenly and is very destructive, so the pressure rod must have sufficient stability.
Steel Construction Process
Design and Engineering:
The process begins with designing the structure and engineering the steel components to ensure strength, stability, and compliance with building codes and regulations.
Fabrication:
Once the design is finalized, steel components such as beams, columns, and panels are fabricated in a factory. Advanced machinery is used to cut, weld, and shape the steel to precise specifications.
Transport and Assembly:
The fabricated steel components are transported to the construction site, where they are assembled using cranes and welding or bolting techniques to form the framework of the building.
Finishing:
After the main steel framework is in place, additional elements such as insulation, cladding, roofing, and interior finishes are added to complete the building.
To sum up, in order to ensure that steel constructions work safely and reliably, the constructions must have sufficient load-bearing capacity, that is, sufficient strength, stiffness and stability. These are the three basic requirements to ensure the safe operation of the components.
