The difference between Q345GJC high-rise buildings steel and Q355C low-alloy steel

Posted:2021-10-09 14:05:58

1. In terms of material quality: Q345GJC is a steel plate for high-rise buildings, and Q355C is a low-alloy high-strength plate. The two are not of the same kind of material.

2. From the point of use: Q345GJC high-rise buildings steel has excellent performance of earthquake resistance, easy welding, and low temperature impact resistance. It is mainly used to construct large-scale high-rise building structures, such as music halls, stadiums, railway stations, etc. Q355C is an ordinary low-alloy steel plate, which is generally used for structural parts such as construction machinery. Q355C material is more common.
