Carbon steel H-beam is an important steel material widely used in construction, bridges, ships, machinery and other fields. Its excellent mechanical properties and welding properties make it play a pivotal role in modern industry.

I-beam is mainly divided into ordinary I-beam, light I-beam and low alloy light I-beam. Ordinary I-beam and light I-beam flanges are thick on the web plate and thin on the outside. Ordinary I-beam, light I-beam, because the cross-sectional dimensions are relatively high, narrow, so the section of the two main sleeve moment of inertia difference is large, which makes it in the scope of application has a great limitation.

Channel steel is a long strip of steel with a groove-shaped section, which is a carbon structural steel for construction and machinery. It is a section steel with a complex section, and its section shape is groove-shaped. Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

‌Carbon steel flat steel‌ is an alloy steel made of carbon as the main component. It is usually made by hot rolling or cold rolling and has specific mechanical properties and chemical composition. Its cross-section is rectangular with slightly blunt edges, the width is between 12-300mm, and the thickness is between 3-60mm‌
. Carbon steel flat bars are widely used in various structures and projects, such as bridges, buildings, automobile manufacturing, industrial pipelines, etc. In the field of construction, carbon steel flat steel is often used to make steel frames in reinforced concrete structures to improve the seismic performance and wind resistance of buildings‌
