Generally produced from low or medium low carbon steel, mesh quality hot rolled wire rod is intended for drawing or cold rolling into smooth or deformed wire, which will subsequently be cross-wire resistance welded in to wire mesh for use as concrete reinforcement. Rods of this type are usually available as rolled and are frequently mechanically descaled inline with the rolling or wire drawing process. Generally speaking, there are practical limitations on drawing this quality of steel rods without intermediate annealing.
Industrial Quality Hot Rolled Wire Rod is produced from low or medium low carbon steel and are generally intended for drawing into industrial, merchant, or standard quality wire. Rods of this type are usually available as rolled, or in thermally treated conditions. Generally speaking, there are practical limitations on drawing this quality of steel rods without intermediate annealing.
Heading quality Hot Rolled Wire Rod is used for heading, forging, or cold extrusion. This wire typically has additional processing done to it for use in a header machine cell. These wire rods are produced by closely controlled manufacturing practices and frequently are
subject to mill testing and inspection to ensure internal soundness and freedom from surface defects, which may adversely affect the cold heading process.
Cold finishing quality hot rolled wire rods are intended for the manufacturing of cold drawn bars. The rods are expected to be substantially free from slivers, laps, and abrupt changes in section, which can impair the desired appearance of the cold drawn bars.
