How are bar marks used in the field?

Explanation:
Bar marks on reinforcing steel serve as quick identification of what you’re using in the field so you can verify it matches the project specs. The mark tells you the bar’s size (diameter), its grade (yield strength), and the manufacturer. With this information, inspectors and crew can confirm the correct bars are placed where required and that they meet the design and code requirements, and it also supports traceability back to the producer. These marks aren’t about color, installation sequencing, or decoration; those purposes don’t apply to how rebar is specified or checked on site.
