Ribbed Deformed Bars provided with lungs, ribs or deformation on the surface to minimise the slippage of the Bar in concrete is used in reinforcing purposes by all advanced countries.
These Bars provided better protection to the reinforcement from corrosion. Cracks in the tensile zonce of these Bard are more evenly distributed and are much smaller in size. With no end hooks, bending. handling and fixing at site is simplified resulting in saving cost of labour, overlaping and joining. Weldable by flash or other processes under controlled conditions.
