GB/T 700
The ordinary carbon structural steel plate under the Chinese national standard GB/T 700 features moderate strength, good low-temperature impact toughness, balanced mechanical properties, excellent weldability, and favorable workability. It is widely used in construction, bridges, vehicles, and general structures across China. The steel grades we supply are: Q275A, Q275B, Q275C, Q275D, Q235A, Q235B, Q235C, Q235D.
GB/T 700 Q235A steel plate is an ordinary carbon structural steel plate characterized by low cost and good workability, suitable for manufacturing static general structures that do not require high toughness or welding performance.
GB/T 700 Q235B steel plate is an economical and practical carbon structural steel plate with balanced mechanical properties and workability.
GB/T 700 Q235C steel plate is a common carbon structural steel plate, widely used in buildings, bridges, vehicles, and general structures in China due to its good plasticity, toughness, and weldability.
GB/T 700 Q235D Carbon Structural Steel Plate has medium strength and good low-temperature impact toughness (-20°C). It is mainly used in building structures in cold regions, engineering machinery, low-temperature containers/pipelines, and other fields.
GB/T 700 Q275 Steel Plate is a medium-strength carbon structural steel plate, mainly used for structural components and mechanical parts that require a certain level of strength.
