The Difference Between Channel Steel And I-steel

Channel steel and I-beam are two kinds of steel commonly used in construction, then what is the difference between channel steel and I-beam? Channel steel and I-steel are different in shape, use, specifications and specifications. Channel steel is a long strip of steel with a groove-shaped section, and I-steel is a long strip of steel with a I-shaped section. I-beam channel steel which bearing capacity is strong? Let's find out.
What are channel steel and I-beams
1, I steel
I-beams, also known as steel beams, are long strips of steel with I-shaped sections. The specifications of the I-beam are expressed by the centimeter value of the waist width, such as the No. 10 I-beam, whose waist width is 10cm.
2. Channel steel
Channel steel is a long strip of steel with a fluted section. It is a carbon structural steel for construction and machinery. It is a shaped steel with a complex section and its section shape is a fluted one.
The difference between channel steel and I-steel
1. Different shapes
I-steel is a long strip of steel with an I-shaped section, while channel steel is a long strip of steel with a fluted section.
2. Different uses
I-beam steel is mainly used in civil construction, and channel steel is mainly used in the field of decoration.
3. Different specifications
I-steel specifications are generally No. 10 to No. 60; The specifications of the channel steel are 5 to 40.
4. Specifications are different
The specifications of the I-beam are expressed by the centimeter value of the waist width, such as the No. 10 I-beam, whose waist width is 10cm. The specification of the channel steel is expressed by the number of millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100*48*5.3, indicating that the waist height is 100 mm, the leg width is 48 mm, and the waist thickness is 5.3 mm, or 10# channel steel.
I-beam channel steel which bearing capacity is strong
The two kinds of steel cross-section shape is different, the selection principle is slightly different, due to the factors of inertia distance and the equivalent cross-section area of the I-steel is better than the out-of-plane stability of the channel steel, usually the compression member or need to consider the out-of-plane deformation of the choice of H steel or I-steel, but the processing of I-steel, node practice is more complex than the channel steel, Therefore, in the case that the structure is not complicated or the rod stress is not large, channel steel can be used. The specific selection shall be determined by the designer through the stress calculation of the scheme comparison. Therefore, for columns, the choice of I-steel is good, for beams, it is appropriate to choose channel steel.
I-beam or channel steel for reinforcement of load-bearing wall? Load-bearing wall reinforcement using I-steel is better, because the cross-section of I-steel is symmetrical, not only the lateral stability is good, and the bearing capacity is stronger, but from the aesthetic and operational point of view, channel steel is not only easy to operate, but also look more beautiful, so many people will use channel steel reinforcement load-bearing wall, we can be comprehensively considered when choosing.
