Channel steel and I-beam are two commonly used steels in construction, so what is the difference between channel steel and I-beam steel? Channel steel and I-beam steel differ in shape, purpose, specifications, and specifications. Channel steel is a long strip of steel with a groove shaped cross-section, while I-beam is a long strip of steel with an I-shaped cross-section. Which I-beam channel steel has strong load-bearing capacity? Let's take a look below.
What are channel steel and I-beam
1. I-beam
I-beam, also known as steel beam, is a long strip of steel with an I-shaped cross-section. The specification of I-beam is expressed in centimeters of waist width, such as the waist width of No.10 I-beam, which is 10cm.
2. Channel steel
Channel steel is a long strip steel with a groove shaped cross-section, belonging to the carbon structural steel used for construction and machinery. It is a complex section steel with a groove shaped cross-section.
The difference between channel steel and I-beam steel
1. Different shapes
I-beam is a long strip steel with an I-shaped cross-section, while channel steel is a long strip steel with a groove shaped cross-section.
2. Different uses
I-beam is mainly used in civil engineering, while channel steel is mainly used in the decoration field.
3. Different specifications
The specifications of I-beam are generally from grade 10 to grade 60; The specifications of channel steel are from 5th to 40th.
4. Different specifications
The specification of I-beam is expressed in centimeters of waist width, such as the waist width of No.10 I-beam, which is 10cm. The specification of channel steel is expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100 * 48 * 5.3, which represents a channel steel with a waist height of 100 millimeters, leg width of 48 millimeters, and waist thickness of 5.3 millimeters, also known as 10 # channel steel.
Which I-beam channel steel has strong load-bearing capacity
These two types of steel have different cross-sectional shapes and slightly different selection principles. Due to factors such as inertia distance and the fact that I-beams with a considerable cross-sectional area have better stability out of plane than channel steel, H-steel or I-steel are usually used for compression components or those that need to consider out of plane deformation. However, the processing and node method of I-steel are more complex than channel steel, so channel steel can be used when the structural stress is not complex or the stress of the member is not large. The specific selection should be determined by the designer through stress calculation through scheme comparison. Therefore, for columns, it is better to choose I-beam, while for beams, it is better to choose channel steel.
Is I steel or channel steel used for reinforcement of load-bearing walls? It is better to use I-beam for reinforcement of load-bearing walls because the cross-section of I-beam is symmetrical, which not only has good lateral stability but also stronger load-bearing capacity. However, from the perspective of aesthetics and operability, channel steel is not only easy to operate, but also looks more beautiful. Therefore, many people will use channel steel to reinforce load-bearing walls, and everyone can consider it comprehensively when choosing.
