1. Ordinary I-beam: light I-beam, due to the relatively high and narrow cross-sectional size, the moment of inertia of the two main sleeves on the cross-section is quite different, so that its application range is very wide and limited. The use of I-beams should be selected according to the requirements of the design drawings.
2. Channel steel use: Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billet of channel steel is carbon steel or low-alloy billet with a carbon content of no more than 0.25%. The finished channel is delivered after being hot-formed, normalized or hot-rolled.
1. Precautions: Regardless of whether the I-beam is ordinary or lightweight, due to the relatively high and narrow cross-sectional size, the moment of inertia of the two main shafts of the cross-section is quite different, so it can only be used directly on its website. A member that bends or forms a lattice-type stressed member in a plane. It is not advisable to use members with axial compression or those perpendicular to the plane of the web and with bending, which makes the range of applications very limited.
2. Introduction to I-beam: I-beam, also known as steel beam, is a kind of long 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 section. Section steel is an efficient and economical cutting steel (there are also cold-formed thin-walled steel, special-shaped steel, etc.). Due to the rational cross-sectional shape, they can make the steel more efficient and improve the cutting capacity. Unlike ordinary I-beams, the flanges of I-beams have been widened and usually the inner and outer surfaces are parallel to each other, making it easy to connect with other components with high-strength bolts. Its size composition is reasonable, the model is 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 size, etc.
3. Introduction to channel steel: channel steel is a kind of long steel strip with a grooved cross-section. It is a carbon structural steel used in construction and machinery. It is a section steel with a complex cross-section, and its cross-sectional shape is grooved. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. China's channel steel imports are greater than exports. The main production areas are Tangshan Iron and Steel, Baotou Iron and Steel, Shandong Iron and Steel, Huangte, Masteel, Baode, Xuangang, Nippon Iron and Steel and many other steel mills.
