concrete reinforcing bar (rebar)
In the United States, the size designations of these (usually) mild steel bars used to reinforce concrete are set by ASTM International.¹ Distributors usually stock rebar in 20- and 60-foot lengths. Besides mild steel, rebar is also made in stainless steel (cost-effective, for example, for concrete bridges where salt is spread on winter ice) and other specialty alloys. Almost all bars are deformed, that is, a pattern is rolled onto them which helps the concrete get a grip on the bar. The exact patterns are not specified, but the See more on sizes the many different rebar grades and how to tell them MillingWhat's the difference between red, yellow and green rebar?But if one end is red and the other end is a different color, it can be welded. In this system, white is grade 33, yellow is grade 40 and green is grade 60. How much does it really matter if I get the right grade of rebar?See all results for this questionWhat's the difference between grade 33 and 33 rebar?Rebar is graded to show the amount of tensile strength it has in terms of pounds per square inch. Grade 33 starts out the low end of strength, with strength increasing as the grade number gets bigger.See all results for this question
What kind of steel is a Grade 4 rebar?
Examine the markings. For example the markings "Z," "4," "S," identifies the piece as a number 4 rebar, made of steel by a manufacturer designated as "Z." If these are the only marks present, then this is a grade 40 bar.See all results for this questionWhat exactly is Mill Scale and what is done about it2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.What Kind of Metal is Rebar and What Can I Use it For the many different rebar grades and how to tell them MillingThe number represents the KSI value, or a thousand pounds per square inch. So a value of 60 means 60,000 pounds of pull before permanent damage, 80 means 80,000 lbs, 100 is 100,000 lbs you get the idea. If there isnt a number here, then its a grade 40.

While not as strong as the higher grades, the flaws in 2-grade lumber are generally not enough to seriously weaken the boards. Avoid using 3- or 4-grade lumber for structural framing applications. If you are hand-picking boards, examine them for knots and other flaws.
