Q235B/Q355B Galvanized steel angle
Q235B is a carbon structural steel with a chemical composition of carbon (C) ≤ 0.22%, manganese (Mn) ≤ 1.4%, silicon (Si) ≤ 0.35%, etc. In the national standard GB700-88, Q235B material is often subjected to temperature shock tests, V-notch, and carbon content between 0.14 - 0.22﹪.
