How is special material steel identified according to the Code of Standard Practice?

Special material steel is identified according to the Code of Standard Practice by being marked by the supplier. This marking process typically includes the application of identification codes or tags that provide essential information about the material, including its specifications and compliance with relevant standards. The supplier is responsible for ensuring that the steel is correctly marked to convey its properties and to help in tracking and verifying compliance throughout the construction process.

While color coding, weight considerations, and RFID tags may be relevant in other contexts or industries, they are not the primary means outlined in the Code for identifying special material steel. The emphasis on supplier marking ensures a consistent and reliable method of identification that aligns with safety and regulatory requirements in the structural steel industry.
