Our History

A Quality, Affordable, Attractive, Permanent Legacy

William Mario Del Zotto, born in 1901, immigrated from Italy to the U.S. during the beginning of the European Arena of World War II. He worked as a bricklayer in the coke ovens of US Steel in Duluth, MN, and helped his son William John Del Zotto get his start in the pre-cast concrete business.

Later on, William John (Bill) Del Zotto founded Del Zotto Manufacturing. Bill started out just making steps and step forms, then septic tanks and septic tank forms. From those early forms, Bill built smarter and more efficient concrete forms by making them safer and easier to strip, pour, and maintain. He invented and patented hundreds of pre-cast forms and equipment. Today, we carry on the legacy, care, and expertise built over the last 100 years to bring you the simplest and best custom steps on the market!

Thank you for the concrete stairs at 3910 W 6th St. that you put in back in 2018. I just sold the house last week. I appreciate your part of the team that made that possible.
