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.
Flats Specifications
MS Flats are generally used in Industrial gratings, various fabrication works & domestically, it is used in grills outside window.
Representation of M.S. Flats is done by the Width (W) & the Thickness (T) of the Flat. For example: When we say 25 X 5 FLAT, it means Width = 25mm & Thickness = 5mm.
Grades & Quality
There are no Primary producers of MS Flats only the Secondary producers i.e. Rolling Mills produces MS Flats. Various Rolling Mills follow the grades & quality specifications given in IS 2062. In general, MS Flats produced by the Secondary Manufacturers passes the physical parameters but fails to match the chemical properties of IS 2062 except few Rolling Mills.
