Q420 Q460 Structural Steel Beams
【GNEE Group Office Environment】
Q420 H profiles steel is a low alloy high-strength structural steel with yield strength of 420 MPa, tensile strength of 520-680 Mpa and material density of 7.85 g/cm3. According to GB/T 1591-2008, Q420 H shape steel beam is classified into 5 quality grades: Q420A, Q420B, Q420C, Q420D and Q420E.
Q460 H beam section has higher strength and higher comprehensive mechanical properties when normalized, normalized and tempered or quenched and tempered (both aluminum deoxidized).Q460 H-beam is mainly used for large engineering structures and light structures that require high strength and large loads.
