2. Application of channel steel: Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment, and vehicle manufacturing. Good welding, riveting performance, and comprehensive mechanical properties are required during use. The raw material for channel steel is carbon steel or low alloy steel billets with a carbon content not exceeding 0.25%. The finished channel steel is delivered after hot forming, normalizing, or hot rolling.

1. Attention: Regardless of whether the I-beam is ordinary or lightweight, due to its high and narrow cross-sectional dimensions, the difference in rotational inertia between the two main axes of the cross-section is significant, so it can only be used directly on its website. A component that bends or forms a grid shaped load-bearing component in a plane. It is not advisable to use axial compression components or components that are perpendicular to the plane of the web and have bending, as this limits the application range.

2. Introduction to I-beam: I-beam, also known as steel beam, is a type of long strip steel with an I-shaped cross-section. I-beams are divided into ordinary I-beams and lightweight I-beams. It is a steel with an I-shaped cross-section. Section steel belongs to efficient and economical cutting steel (other types include cold-formed thin-walled steel, special-shaped steel, etc.). Due to their reasonable cross-sectional shape, they can make steel more effective and improve cutting ability. Unlike ordinary I-beams, the flange of I-beams has been widened, usually with parallel inner and outer surfaces, making it easier to connect with other components using high-strength bolts. Its size composition is reasonable, the models are complete, and it is easy to design and choose. The selection of I-beams in structural design should be based on their mechanical properties, chemical properties, weldability, structural dimensions, etc.

3. Introduction to channel steel: Channel steel is a long steel strip with a groove shaped cross-section. It is a carbon structural steel used in construction and machinery. It is a type of steel with a complex cross-section, and its cross-sectional shape is a groove. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment, and vehicle manufacturing.
