1. Rationale – The project is in line with our strategic plan to double the downstream capacity in FRP and extrusion segments in next five years. Demand from both FRP and extrusion is growing rapidly in India. This capacity addition by the company will help to cater to growing demand from FRP customers.

This is for your information and records.
