Cold Rolled Steel Bar

Cold Rolled Steel Bar
Cold rolled steel is produced by a rolling metal forming process where the metal stock passes through one or more pairs of rolls to provide uniformity and reduce the thickness of the metal. If the temperature of the metal being rolled is below its recrystallization temperature, the process is called cold rolling.

Cold rolled steel bar is a kind of steel product made by special processing process. It conducts cold processing process such as cold pull and cold pull at room temperature, so as to obtain more accurate size and excellent physical properties. This reinforcement usually exhibits high strength, high hardness and good corrosion resistance, making it outstanding in various engineering applications. The surface quality of the cold roll round bar is very good. After the cold rolling treatment, the surface flatness is high and smooth without distortion, which makes its bonding ability with concrete stronger and improves the stability of the overall structure. In addition, the cold rolled steel rod also has good ductility and toughness, although its ductility is slightly worse compared to the hot rolled steel bar, but it can still maintain good performance under high strength load.

Cold Rolled Steel Bar Characteristics
Surfaces are more finished and tolerances are tighter.
Cold rolled steel bars are true and square, with sharp edges and corners.
Smooth surfaces tend to feel greasy.
