AZCO® History Timeline

AZCO INC. was founded over 50 years ago with the vision of providing customers with complete industrial construction services from A to Z.

This foresight has become the foundation of what our company is today: an employee owned, full service industrial constructor and fabricator.

Our commitment to our customers is to complete contracts on schedule and within budget. We keep this promise by providing our customers with dedicated people with special skills and in-depth experience.


1949

Four individuals identify a need in the Fox Valley for a quality mechanical contractor to serve the industrial marketplace. Together they form AZCO INC., signifying service offerings from A to Z.
