Construction steel refers to all kinds of steel used in construction projects, mainly including steel bars, section steel, plates, pipes, etc. According to different functions and uses, commonly used construction steel can be divided into the following categories:
1. Steel bars
Rebar is the most widely used steel in construction engineering, and its main function is to strengthen the tensile strength of concrete. According to different diameters and grades, steel bars can be divided into various specifications. In construction, steel bars are mainly used in concrete structures such as beams, columns, slabs, etc.
2. Section steel
Section steel is a kind of steel with I, H, U-shaped cross-sections, which can be divided into various types according to their cross-sectional shapes. Section steel has high strength and plasticity, and is often used in supports and connectors of bridges, building structures and mechanical equipment.
3. Plate
Plate is a kind of flat steel, which can be divided into thin plate and thick plate according to the thickness. In construction, panels are mainly used for structural parts such as wall panels, roof panels, floors, and floor slabs. The selection of the board should consider factors such as its bearing capacity, corrosion resistance, fire resistance and aesthetics.
4. Pipe
Pipes are steel products with circular cross-sections, which can be divided into seamless steel pipes, welded steel pipes, spiral steel pipes, etc. according to their uses and characteristics. Pipes are widely used in drainage, ventilation, water supply, heating and other systems of buildings, and are also commonly used in bridges, tunnels and marine engineering and other fields.
In summary, commonly used construction steel can be divided into four categories: steel bar, section steel, plate and pipe. When using construction steel, it is necessary to select the appropriate material according to its characteristics and functions to ensure that the construction
safety and stability of the building structure. At the same time, it is also necessary to pay attention to the protection and maintenance of the steel during the construction process to prolong its service life.
