A36/A572 Grade 50/60/65 Galvanized steel angle
American standard H-beam A36 is a carbon structural steel with excellent performance. It is made by adding a certain amount of alloy elements such as silicon, manganese, phosphorus, etc. to ordinary low-carbon steel. Its main component is iron, the carbon content does not exceed 0.2365%, the silicon content is between 0.15% - 0.40%, the manganese content is between 0.30% - 0.60%, and the phosphorus content is between 0.035% - 0.045%. The reasonable ratio of these elements makes A36 have excellent performance in strength, hardness and toughness. It also has excellent plasticity and weldability.
