  • OSHA Upgrades

With the size and scope of water storage tank projects that Maguire Iron handles across the country, we have assembled a high-quality team of project managers and coordinators to personally handle every project from start to finish. Our project management team is experienced in all facets of the construction process. This experience and knowledge ensure a single point of contact for communication on each project. Maguire Iron prides itself on handling all details of a project in a timely and professional manner.


One of the things that set Maguire Iron apart from the competition is we have over 100 years of experience painting all sizes and styles of water tanks. We believe that choosing the best coating system for your tank is paramount to protecting your investment long-term. That is why at Maguire Iron we only use the highest quality interior and exterior coating systems and apply them according to the American Water Works Association (AWWA). If you are looking for a tank that makes a statement we can work with you to design a paint scheme that will get noticed. We can help you design a specialized logo or graphics to advertise your community or business.


Maguire Iron has always believed in manufacturing high-quality tank parts. We use them on every new water storage tank we build. This philosophy has led us to begin manufacturing and selling water storage tank parts for existing tanks across the country. Our tank parts meet all OSHA regulations and are made from high-quality American made steel in our Sioux Falls facility by a team of experienced metal fabricators. This process allows us to maintain superior quality with competitive pricing and timely delivery.
