In a division, the rebar is classified into two branches and coils. The coil rebar, as its name implies, is twisted into coils.

There are two types of coil rebar:

1. Simple coil
2. Ribbed coil

SAE 1006 and SAE 1008 wires are also classified as low carbon steels. The parameters related to the hot rolling process for this group of wires are different from the previous samples due to their different chemical analysis and microstructure. The chemical analysis as well as the mechanical properties of these wires according to ASTM standard are presented in the table below.
