How do you identify rebar?
One of the easiest is to look for the stamped numbers and letters between the lines on the rebar. This may include a set of three characters, such as B6S. This means that the manufacturer is shown by the letter B, it’s grade 60 rebar and it’s made of steel. If there’s another number there, that may show rebar sizes.
What does rebar look like?
Rebar’s surface is often “deformed” with ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns.
What are the sizes of rebar?

How far should rebar be placed from edge of concrete?
Reinforcement should also be placed low enough so saw cutting does not cut the reinforcement. For welded wire reinforcement, the Wire Reinforcement Institute recommends steel placement 2 inches below the surface or within the upper third of the slab thickness, whichever is closer to the surface.
What do the numbers and letters mean on rebar?
It’s actually quite easy. The number represents a unit of 1/8 of an inch. So that means a #4 rebar is 4 times 1/8″ or in other words – 1/2″. #5 bar is 5/8″; #6 bar is 3/4″ and so on. To cut and bend your rebar, check out the rebar cutters and rebar benders at Fascut Industries.
How do you choose rebar size?
Contractors sometimes use the “1/8 Rule,” meaning the size of the rebar is 1/8 the thickness of the slab. For example, a slab that is 6 inches thick might have rebar marked as size 6 or 3/4-inch.
