Marilao Tube Center, founded in 1989, has rapidly become one of the foremost names in the B.I. (Black Iron) Tube market.  The Plant site is located in Sta. Rosa Marilao, Bulacan.  It was founded on the desire to achieve commercial success and technological excellence.  Its main products are B.I square tube, rectangular tube, and round tubes.

    We believe that we must conduct our business in a manner that is constructive, honorable, and mutually profitable for stockholders, employees, customers, suppliers, and the general community.  We believe that we can make a contribution to society by providing B.I.tubes of superior quality at a fair price. The value of our contribution to our nation's progress will be measured by our growth and profitability. Our profitability is proof that we are needed. We believe that we have earned the right to be where we are today. To this end, we will continue to strive to improve ourselves in the hope that we can build an institution whose contribution to society will last beyond our lifetime.
