What do ASTM Specifications require to be printed on each reinforcement bar?

• A. A symbol or marking to indicate the type of steel, a letter or symbol to show the producer's mill, and markings to designate steel grade
• B. A manufacturing date
• C. The bar's weight per foot
• D. A color code for the grade

Answer: (A)

Reinforcement bars must carry permanent marks that identify what kind of steel they are, who produced them, and their grade. ASTM specifications require printing a symbol or marking to indicate the type of steel, a code (letter or symbol) for the producer’s mill, and markings that designate the steel grade (such as Grade 60 or Grade 75). This labeling ensures traceability, quality control, and that the correct material is used on a project. Other items like a manufacturing date, the bar’s weight per foot, or a color code for grade are not specified as standard print markings by ASTM.
