Gi Square Tube Q345 Description
Q345 is a low-alloy steel commonly used in automobiles, bridges, ships, and buildings. The "Q" stands for yield point, and "345" represents the yield strength. As the material thickness increases, the yield value decreases. The tensile strength range of Q345 is 470 to 660 MPa, indicating its ability to withstand high-stress conditions. Q345 steel pipes come in round and rectangular shapes. Q345 rectangular pipes are often used as structural pipes, and to extend their lifespan, the surface is often galvanized.
