The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.

Q235 vs. Q345 Steel Plate (How to Distinguish) MachineMfg

When the general strength design is presented, Q345 is used because Q345 is not only strengthened than Q235 but also save 15% to 20% steel compared to Q235 steel. However, for stability control design, Q235 steel is better. The price difference is 3%- 8%. Regarding how to distinguish the steel plate from Q235 and Q345, therere several methods:Q345 Galvanized steel pipe - xiongyigtQ215Grade C,CS Type B, SS330, SPHC Q235---Grade D, SS400, S235JR, S235JO, S235J2 Q345---SS500, ST52S355JR Dimensions 16-1020mm (1 2inch~ 40 inch) Length 2000-16000mmor as required Standard ASTMAISIJISGB DINEN Surface treatment Cold galvanizingHot dip galvanized Zinc Coating pre galvanized steel pipe q345 steel steel typeQ345 Steel Price, 2020 Q345 Steel Price Manufacturers q345 steel steel typeQ235 Q345 C Type C Shape Channel Steel Prices.
