About Us

We are a family run manufacturing unit that has been supplying standardised and custom grades of PCC to clients of all scope and sizes since 1999. We ensure consistent high quality and adherence to strict standards. Most of our clients end up working with us in the long term, often entrusting all of their PCC demand with us. We pride ourselves in having honest business practices, swift communication and industry leading product quality.
Our Founder
Our foray into manufacturing happened under the leadership of Late Lt. Cdr. V.C.P Vashisht, who set up a steel furnace in 1980, after retiring from the Indian Navy. He was among the very first businessmen to start manufacturing in Kala Amb, setting the way for the highly industrialized, present day version of this city. His absolute honesty, leadership qualities and hard-working nature are still well known among our customers, officials, staff and fellow industrialists alike.
