Humble Beginnings

Joseph Lombardo, an Italian immigrant, founded State Supply in 1933. Driven by an entrepreneurial spirit and necessity, Joe saw a business opportunity to provide for his family during the Depression. He would source and deliver plumbing and heating repair parts to customers for a fee. State Supply not only survived during this period but continued to grow through the years – even with challenges along the way, including the disruption of WWII and a devasting fire that destroyed their first building in 1962. 


Staying true to its founding principles through it all – working hard to earn its customers' trust.

The guiding principles Joe built his company on still hold today. Customer satisfaction is State Supply's number one priority. To this end, we've built a team of knowledgeable, trustworthy product specialists. We source from only the best-in-class vendors and manufacturers and stock over 30,000 items with same-day delivery. The name State Supply has become synonymous with dependable business partner. We're now considered the nation's largest distributor of steam traps and repair parts in the industry.


We help our customers find the right solution the first time.

Still a family-run business today – State Supply is led by the third generation Lombardo's. While the company remains humble to its St Paul roots, we now operate on a much larger scale, serving more than 50,000 customers nationwide and even internationally.
