Q420 Series
Q355 Series
Q390 Series
China's structural steel grades are widely used in buildings, bridges, industrial plants, mining equipment, machinery, and infrastructure projects. The most common grades include the Q355, Q390, and Q420 series, which offer different combinations of yield strength, weldability, toughness, and low-temperature performance.
Among them, Q355 structural steel is one of the most widely specified materials for general steel structures due to its balanced mechanical properties and excellent weldability. For projects requiring higher strength, Q390 and Q420 provide increased load-bearing capacity while maintaining good fabrication performance. Depending on service conditions, these grades are available in multiple quality levels such as B, C, D, E, as well as weather-resistant (Q355N Series) and bridge structural steel (Q355M Series) variants.
At CEHE STEEL, we supply a complete range of Chinese structural steel plates in accordance with GB/T standards, with customized cutting, third-party inspection, and worldwide export services available for construction, fabrication, and heavy engineering projects.
