Q235B Steel is a widely used carbon structural steel grade under the Chinese GB/T 700 standard. Known for its good strength, weldability, formability, and cost-effectiveness, Q235B carbon steel coil is commonly used in construction, steel fabrication, machinery manufacturing, pipes, and general industrial applications.
Compared with Q195 steel, Q235B provides higher strength and better structural performance, making it suitable for load-bearing and fabrication purposes.
The "B" grade means the material has impact toughness requirements at room temperature (20°C), offering more stable mechanical performance than Q235A.
Q235B carbon steel is commonly supplied in hot rolled coil (HRC), cold rolled coil (CRC), pickled & oiled coil, and galvanized coil.
