In comparison to normal hot rolled bars, a cold finished product gives tighter sectional tolerances, improved straightness, and a clean surface. The main advantage to the user is that material can be bought closer to the finished machine size and thus reduce machining costs. It minimises costly straightening operations and is more easily machined. Another benefit of cold drawn bar is a marked increase in physical strength over a hot rolled bar of the same section.
