Steel Channel Q235B
Steel Channel Q235B
Channel steel belongs to carbon structural steel for construction and mechanical use, it is the section steel with complex cross-section, and its cross-section shape is groove.
Channel beam 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.
Steel U beam Q235B is a carbon structural steel, belongs to the ordinary carbon steel grade.
Its chemical composition and mechanical properties are suitable for general engineering structures and part of the machinery manufacturing.Q235B in the ‘Q’ on behalf of the yield point of the steel, and the number ‘235’ that the yield strength of 235MPa, and the letter ‘B’ to represent the yield strength of 235MPa.The letter ‘B’ indicates its quality grade.

U BEAM
The raw material billet of channel steel is carbon steel or low alloy steel billet with carbon content not more than 0.25%. Finished u channel beam by hot forming, normalised or hot rolled state delivery. Its specifications to waist height (h) × leg width (b) × waist thickness (d) of the number of millimetres, such as 100 × 48 * 5.3, said the waist height of 100 mm, leg width of 48 mm, waist thickness of 5.3 mm channel steel, or 10 # channel steel. Waist height of the same u steel channel, such as several different leg width and waist thickness also need to be differentiated in the right side of the model plus a, b, c, such as 25 # a, 25 # b, 25 # c and so on.
Mechanical properties
Q235B channel steel has high yield strength and tensile strength, which makes it able to withstand large loads and impacts. Its yield strength is usually between 215MPa and 235MPa, while its tensile strength is between 370-500MPa. These excellent mechanical properties make Q235B channel steel perform well in the occasions where it is subjected to heavy loads and impact loads.
Plasticity and toughness
Q235B channel steel has good plasticity and toughness, which makes it not easy to break or deform during processing and use. Its elongation is usually within a certain range, which ensures that the steel can produce a certain deformation without fracture when subjected to external forces.
Excellent welding performance
Q235B channel steel has excellent welding performance, which makes it easy to weld and connect in the manufacturing process. Through reasonable welding process and choice of welding materials, it can realise the firm connection between Q235B channel steel and ensure the stability and safety of the overall structure.
Good corrosion resistance
Q235B channel steel shows good corrosion resistance under most environmental conditions. It can resist a certain degree of oxidation and corrosion, ensuring the service life and safety of the steel. However, under special environmental conditions, such as strong acid, strong alkali and other corrosive media, the corrosion resistance of Q235B channel steel may be affected to some extent.

Brief description：
In addition to its application in the field of construction and engineering, Q235B hot rolled steel channel also has some economic value, because of its relatively low price, easy processing and forming, so it is widely used in the manufacturing industry. At the same time, the recycling and reuse value of Q235B channel steel is also high, which is important for resource conservation and environmental protection. However, it should be noted that Q235B steel channel hot rolled may have certain limitations in special environments, such as changes in mechanical properties in high or low temperature environments, as well as poor corrosion resistance, so proper protection and maintenance are required during use.
