When the grade number 60 is marked on the bar, where is it located?

• A. 4th mark in order
• B. 1st mark
• C. 2nd mark
• D. Between the main ribs

Answer: (A)

Grading information is stamped on reinforcing bars as a fixed sequence of marks along the length. The number 60, which denotes Grade 60 steel (about 60 ksi yield strength), is placed as the fourth mark in that identification sequence. So, when you read the marks from one end, the grade 60 appears as the fourth imprint. It isn’t simply located in a spot like between ribs—the markings follow a standard order, and the grade value is the final stamp in that sequence.
