Rebars and Wire Rods

Rebars and Wire Rods

Rebar, short for “reinforcing bar” or “reinforcement bar”, is a metal bar that is used to help increase the tensile strength of concrete. As a result, it helps concrete structures withstand tensile, bending, torsion, and shearing loads. Since these are areas of weakness for concrete, rebar strengthens concrete structures that would otherwise fall apart under these forces.

Steel wire rod is a semi-finished product which is rolled from steel billet in a wire rod mill and is used primarily for the manufacture of wire. The steel for wire rod is produced by all the modern steelmaking processes, including the basic oxygen and electric furnace processes. Steel wire rod is usually cold drawn into wire suitable for further processing such as cold rolling, cold heading, cold upsetting, cold extrusion, cold forging, or hot forging. Although wire rod is produced in several regular shapes (round, square, hexagonal, and rectangular), most of the wire rods rolled are round in cross section. Round wire rod is usually produced in nominal diameters of 5 to 15 mm, advancing in increments of 0.5 mm.
