|
|
|
|
|
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. |
