Steel wire is one of the four major varieties of steel: plate, tube, profile and wire. It is a reprocessed product made of hot-rolled wire rod by cold drawing. According to the section shape, it mainly includes circle, square, moment, triangle, ellipse, flat, trapezoid, zigzag, etc. Ordinary quality steel wire includes steel wire for welding rod, nail making, mesh making, packaging and printing industry.

ASTM A510 A510M wire is one of the most widely used steel varieties. After rolling, it can be directly used for reinforcing and welding structural components of reinforced concrete, or it can be further processed for use.

High carbon steel is used to make spring tempered carbon steel wire. Commonly used grades of spring steel wire do not have a specific chemical name. They are instead specified and manufactured according to performance criteria specific to their primary end use, which is the manufacture of coil springs. These performance standards allow a range of carbon content, but there are other factors, such as tensile strength and bending/winding tests must be met within the specified range.

Low-carbon bright alkaline steel wire is a good general-purpose grade and is the most common type in daily life, such as hangers, electrical shelves, store displays and paper clips. It has good bending and flattening performance, is easy to form, and is conducive to welding.

PC Strand, or prestressed concrete steel strand, is a twisted steel cablecomposed of high strength steel wires and is stress-relieved(stabilized)for prestressed concrete or similar purposes.
