Grade 40 or Grade 60 indicate to yield strength of steel and for more information
♦ Grade60
Rebar offers a minimum yield strength of60,000 pounds per square inch, or420 megapascals on the metric grading scale. It also features a continuous line system, with one line running along the length of the bar which is offset a minimum of five spaces from the center. These characteristics make grade60 rebar particularly well-suited for medium- to heavy-duty concrete reinforcement applications.
Designation offers a minimum yield strength of40,000 pounds per square inch and conforms to ASTM A-615 performance standards. Its metric counterpart is grade280 rebar, with an equivalent minimum yield strength of280 megapascals. This makes grade40 rebar an excellent choice for light- to medium-duty concrete reinforcing applications.
