Q345 Q355 Hot Rolled H Beam
Q345 Q355 Hot Rolled H Beam Products Description
Q345H-shaped steel is a low-alloy H section steel commonly used in motor vehicles, bridges, ships, construction and other fields. Also known as GB/T 1591, the Q in Q345 represents the yield point, and 345 represents the yield strength. The yield value decreases as the thickness of the material increases.
Q355 H Beam Steel is an economical section steel. It is widely used in industry, construction, bridges, oil drilling platforms and other aspects. It is usually used as a beam or column in a building which gives full play to its characteristics because Q355 steel beam H has excellent lateral resistance in the strong axis direction. Q355 Structural Steel Beams can be divided into two types according to the production method, hot rolled and welded. Among them, the production process of welding H profile steel is to cut the strip steel of moderate thickness into the required width, and then weld the edges and waist together on the welding machine. The production process of hot rolled H shape steel beam is to heat the strip for rolling, and then cut and correct. We have more than 10 years of production and export experience. If you have Q355 H beam or other steel H beam grade customization needs, please contact me.
