Q345qC Q345qD H Steel Profile
Q345q there are three levels of grades: Q345qC = 0 ℃ impact, Q345qD = -20 ℃ impact, Q345qE = -40 ℃ impact
Q345qC belongs to the national standard bridge steel, the implementation of the standard: GB/T714 special technical conditions. Q345qC h shape metal brand in the Q = steel yield; 345 = steel yield strength; q = bridge structural steel; C = steel grade.
Q345qC h beam section is mainly used in the bridge engineering and construction industry to manufacture bridge structures.
Q345qD Yield strength δɡMPa: 345-305; Tensile strength δbMPa: 510-490; Elongation δ5%: 21.
Q345qD H-section steel beam is often used more in bridge structure manufacturing industry such as; bridge equipment manufacturing, bridge structure engineering and so on.
