GB Q235B Hot Rolled Carbon Steel Plate – Popular Chinese Standard Structural Steel Worldwide

Q235B is the mainstream carbon structural steel plate governed by Chinese GB/T 700 standard. Q denotes yield strength, 235 refers to its minimum yield strength value (235 MPa), and letter B means the material undergoes room temperature V-notch impact test. It is one of the most exported steel grades from China and recognized by global steel purchasers for general structural use.
Q235B exhibits excellent comprehensive processing performance, including easy welding, bending, cutting and machining. Raw material cost is competitive, and stable mass production guarantees consistent batch quality. As long as standard welding processes are followed, cold and hot forming can be completed smoothly for most fabrication demands.
Q235B steel plate is widely used in factory steel structures, steel brackets, atmospheric storage tanks, metal brackets, construction templates and general mechanical parts. It is highly favored by global trading companies and steel processing plants. We can supply Q235B plates in various sizes and provide official mill test certificates for international trade.
