Q460GJB Q460GJC Universal Steel Beams
There are four grades of Q460GJ steel: Q460GJB, Q460GJC, Q460GJD and Q460GJE.
Q460GJC h profile steel is one of the grades of steel used in high-rise buildings, GJ means high-rise building, and C is one of its grades. This grade is widely used in the construction of high-rise buildings because it has good performance and can be added some other properties according to the needs of customers.
Q460GJC h beam profile is used in a large number of applications in the manufacture of high-rise building structures, large-span structures and other important building structures. Building structural steel, steel used in the construction of high-rise and important building structures. Requirements for high impact toughness, adequate strength, good welding properties, a certain flexural strength ratio, if necessary, also requires the thickness of the directional properties.
Q460GJC h profile steel Mechanical properties:
The thickness of the sample used in the experiment is: 25mm; tensile strength σb (MPa): ≥ 550; yield strength σs (MPa): ≥ 460; elongation δ5 (%): ≥ 17; section shrinkage ψ (%): ≥ 40; impact work (longitudinal) Akv (J): ≥ 34; yield ratio: ≥ 0.85.
Q460GJB steel beam h Mechanical properties:
Tensile strength σb (MPa): ≥550; yield strength σs (MPa): ≥460; elongation δ5 (%): ≥17; section shrinkage ψ (%): ≥40; impact work (longitudinal) Akv (J): ≥47; yield ratio: ≥0.85.
