A36/A572GR50/A992 W12x65 W12x72 W12x79 h beam profile
A36 h type beam is an American standard carbon structural steel that complies with the ASTM A36/A36M standard. It is widely used in construction, bridges, machinery manufacturing and other fields. It is suitable for welded or bolted structural parts and is equivalent to the domestic Q235 h section steel.
The yield strength of A36 h shaped beam is ≥250 MPa (minimum value), the tensile strength is 400~550 MPa, and the elongation is ≥20% (excellent plastic deformation ability).
A572GR50 h beam section is an American standard high-strength low-alloy structural steel that complies with the ASTM A572/A572M standard. The yield strength of A572GR50 steel h profile is ≥345 MPa (50ksi), the tensile strength is 450–585 MPa (65–85ksi), and the elongation is ≥18%. It is suitable for high-load scenarios such as bridges and buildings.
A992 h metal beam is an American standard high-strength low-alloy structural steel, specially designed for the construction field, and implements the ASTM A992 standard. The yield strength (MPa) of A992 h section steel is ≥345. It has the properties of high strength, high toughness and corrosion resistance, and is widely used in high-rise buildings, bridges and other load-bearing structures.
