Why is Rama TMT the right choice to ‘build it right’?
Rama TMT is an example of ‘Innovation meets products excellence’. Striking a fine balance between the life of the structure and its cost, these corrosion resistant bars help in reducing the rate of corrosion from the time of construction and thus enhance the life span of the structure.
