A500 is an important technical standard developed by the American Society for Testing and Materials (ASTM), which is specifically used to regulate the production and quality control of cold-formed welded and seamless carbon steel structural pipes. The ASTM A500 standard covers carbon steel structural pipes in multiple shapes, including square, round, rectangular and special sections. This standard is widely used in projects such as bridges and buildings. Among them, Grade C is a specific material grade used in medium-strength structural scenarios. Compared with other grades, Grade C has achieved a good balance between strength and toughness.
