CINCO IRON WORKS was established as a sole proprietorship. Its President, Luis M. Diaz, who began operations with one worker, started the company in 1992. Beginning as an ornamental metal fabrication and installation company, the business in a short span of years, has cemented a position in the Southern California area as a company who serves its clientele with unparallel timeliness, quality and craftsmanship.

CINCO IRON WORKS, INC commenced operations in 1997 when the company was converted to a California corporate entity. Highly regarded in the marketplace, CINCO has steadily increased sales and profits and is the owner of its own building of operations constructed in 2000.

The name, CINCO (Spanish for Five), represents the size of the owner's family and is dedicated to the success of his family and assisting others. That dedication aspires to contribute to the economy through the provision of work for more people, be the top performer in steel fabrication and a benevolent force in the community.
