FIVE DECADES OF FORWARD MOTION

CIW began in 1972 with the vision and determination of its founder, Jim Gonsalves. After years of experience in steel fabrication and industrial production—often working 36 hours straight without sleep—Jim purchased a small ornamental iron business in Pacheco, California, called Concord Iron Works.

Today, three generations of the Gonsalves family proudly continue Jim’s legacy. CIW remains a family-owned business and a recognized leader in Structural Steel and Miscellaneous Metals, with a commitment to exceptional product quality, consistent service, and on-time delivery.
