According to the color of the steel plate, the Q235 and Q345 materials can be distinguishedthe color of Q235 is blue, and the Q345 is red (this is only for the steel that just came into the market, and if the time is long then it also cannot be distinguished). The most distinguishable test is chemical analysis.
