Characteristics |
H-shaped steel |
Q235, Q345, Q390, etc. |
The cross-sectional shape is reasonable, with excellent mechanical properties, strong bending resistance, convenient construction, and can save steel. |
Industrial plants, high-rise buildings, long-span bridges, etc |
I-beam |
ordinary I-beams, light I-beams, such as I10, I12.6, etc. |
The cross-section is I-shaped, capable of withstanding significant bending moments. |
The beam and column structures of general buildings, such as small buildings, temporary buildings, etc. |
channel steel |
[5, [8, [10 and so on |
The cross-section is in the form of a groove, simple to manufacture, and can be used to withstand certain lateral loads and moments. |
Purlins and wall beams in building structures, frame structures in mechanical manufacturing, etc. |
angle steel |
Equal angle steel (such as ∠30×30×3), unequal angle steel (such as ∠50×32×4) |
Simple in shape, flexible in use, can be used for connections, supports, etc. |
The connection of steel structure nodes and fabrication of small components, such as angle steel brackets, power transmission towers, etc. |
steel plate |
Q235B, Q345R, etc. |
It can be processed into various shapes and sizes as needed, with high strength and strong load-bearing capacity. |
Beams, columns, foundations, etc. of building structures, such as the core of high-rise buildings, steel beams of large bridges, etc |
Round steel pipe |
Q235, Q345, etc. |
Good compressive and flexural performance, simple and beautiful appearance, can withstand greater pressure and torque. |
The columns and supports of building structures, such as the structural supports for large-span buildings like stadiums and exhibition halls. |
Square steel pipe |
Q235, Q345, etc. |
The cross-sectional shape is regular, which facilitates connection and processing, and has good compressive and bending resistance properties. |
The framework of building structures and curtain wall supports, such as the exterior decorative structures of modern buildings. |
