Carbon steel round bar is a common metal material, mainly composed of carbon and iron, with high strength and good machine ability. It is widely used in fields such as construction, machinery manufacturing, bridge construction, shipbuilding, etc. The diameter range of carbon steel round steel usually varies from a few millimeters to several hundred millimeters, and can be customized according to needs. Its performance includes corrosion resistance, durability, and tensile strength between 420MPa and 540MPa. The quality level is usually Grade 1, and the surface is smooth and not easily deformed. The execution standards for carbon steel round steel are mostly national standards to ensure product quality and safety. During use, it is important to choose appropriate specifications and materials to meet the needs of different projects. We currently have this type of product in our store. Our carbon steel round bars come in a complete range of specifications, with diameters ranging from 6mm to 700mm. We provide cutting and welding services, which are corrosion-resistant, sturdy, durable, and have high tensile strength. We have sufficient inventory and are available for nationwide distribution.
