What is the required way to identify fabricators' stock steel material?

In the context of identifying fabricated stock steel material, certified mill test reports are essential because they provide detailed documentation of the steel's properties, including chemical composition, mechanical properties, and other critical specifications. These reports are generated by the steel mill and verify that the material meets the standards and codes required for construction and engineering projects.

Using certified mill test reports ensures that the steel complies with relevant specifications and standards, which is crucial for safety and integrity in structural applications. This documentation is typically tied to specific batches of steel and serves as a reliable resource for engineers, inspectors, and project managers who need to verify the material's quality and suitability for its intended purpose.

While barcode labels, manufacturer's certificates, and visual inspection tags play roles in material management and identification, they do not provide the comprehensive and certified data offered by mill test reports. Barcodes may assist in inventory tracking, manufacturer's certificates affirm the source but can lack detailed material properties, and visual inspections do not provide quantitative analysis necessary for verifying compliance with engineering standards.
