What are the technical advantages of cold forming ribs on small reinforcing bar?
One obvious advantage is to produce ribbed bar below the smallest hot rolled product (6mm).
Is the hardening induced by cold working of any value, or is it detrimental when processing the ribbed bar?

With the right placing ribs and lugs, the TMT barshttp://rightsteel.in/importance-of-lugs-and-ribs-are-on-tmt-rods/ can give the structures an optimum lifespan as well as stability. As the heights and complexities go upwards, the importance of properly placed ribs at correct angles has only gone up. 

There have studies which have proved that lugs and ribs have in fact been effective in increasing the bendability and concrete bonding index. This has also led to reducing the length of TMT bars while retaining the strength and tensile strength. These ribs and lugs also reinforce the protective coating against rust and corrosion which is painted on all TMT bars.
