High quality A992 W30x173 W30x191 w flange beam
A992 structural steel h beam is a low alloy structural steel of American standard, which is implemented in ASTM A6 standard. It is designed for high strength and high fatigue resistance and is suitable for dynamic load environment.
The chemical composition of A992 steel beam h optimizes weldability and corrosion resistance, with yield strength ≥345MPa (50ksi), tensile strength 448-517MPa (65-75ksi), and elongation ≥18%.
Performance advantages of A992 h shaped beam
Strength-to-weight ratio: large section moment of inertia and modulus, strong bending resistance, and can reduce the deadweight of the structure.
Seismic resistance: can absorb energy through plastic deformation under dynamic load to improve safety.
