About Us

A Brief History

McCullough Steel Products was started in April, 1974 in a 4,000 square-foot building. We now have over 60,000 square feet in 3 locations.

We have grown to represent some of the finest manufacturers of piping materials and plumbing suppliers in the world and keep an in-depth stock. In April of 2006, Mary Connor Adcock, Mr McCullough's daughter, bought the company.

McCullough Steel Products has been built on integrity and the ability to ship quality products quickly. We maintain one of the largest inventories in the Southeast and pride ourselves on total customer committment.

We couple quality products with the best customer service available. Our sales staff has over 200 years combined experience to help you locate even the hardest-to-find item.
