We sell all type of TMT bar from 8mm to 40 mm diameter from primary and secondary producer.Reinforcement bars are used generally in construction projects.
Basically there are 3 Qualities in bars:-
♦ CTD : Cold Twisted Deformed Bars ♦ TOR : Tor – 40 ♦ TMT : Thermo-Mechanically Treated Bars
CTD & TOR-40 :
CTD & TOR -40 are old forms of reinforcement bars but are now obsolete because CTD name itself suggests that it is “cold twisted deformed” bars. And it is twisted when it is cold, which leads to surface crack which makes the product more prone to corrosion. TMT Bars are much easily available and is of superior quality than CTD & TOR-40.
TMT Bars:
Representation of TMT bars is done by its diameter. For e.g.: 8mm TMT bar means diameter of that bar is 8mm.
