TMT Saria Is Better Then The Prescribed Standards -
The Indian Standard Bureau and International Standards Bureau prescribe certain maximum chemical composition of Carbon. Sulphur and Phosphorus. Our products even further better these. standards. Similarly, even for mechanical properties our products surpass the prescribed standards . We do this to .satisfy the needs of our esteemed customers for a good quality product and to give them maximum value for their money. The following tables would make the picture more clear:-
