Q345 S235 U Section Steel

Q345 Steel is a type of low-alloy steel, that is used in the manufacturing of bridges, buildings, and other structures. It has a yield strength of 345 MPa and tensile strength of 470-660 MPa. S235 grade steel is a readily weldable low carbon manganese steel with good impact resistance (including in sub-zero temperatures). This material is commonly supplied in the untreated or normalised condition and is available in several variations (denoted by additional letters and/or digits), which offer slight modifications of chemical composition and mechanical properties.
