Carbon Steel Pipe

Q235-A Carbon Steel Tube/Pipe

Q235-A Carbon Steel Tube/Pipe is a tubular product adhering to the Chinese national standard (GB/T 700) for general structural carbon steel. The "Q" stands for Yield Strength, and "235" indicates a guaranteed minimum yield strength of 235 MPa (for wall thicknesses ≤16 mm). The "-A" designation specifies the lowest quality grade among the Q235 classifications, allowing for less stringent control over impurities and generally not requiring impact testing. This steel offers a practical combination of moderate strength, good weldability, and desirable plasticity at a cost-effective price. Q235-A Tube/Pipe is one of the most widely used materials for general structural supports, scaffolding, low-pressure fluid pipelines, and non-critical mechanical components in construction, civil engineering, and general manufacturing where basic mechanical properties are sufficient.
