Reinforcing steel bar i.e. rebar is widely used in the construction industry. Such rebar having deformed shapes with ribs like herringbone, spiral or crescent shaped long products either in coil or straight form can well combine with concrete in civil engineering construction for unique mechanical properties and tighter adherence for surface ridges. The feature that makes rebar so strong is the presence of many small ridges which help in keeping huge load of weight avoiding slipping. This is why proper threaded fastening is so important.
