Niles Steel Tank

What Niles Steel Tank does

Niles Steel Tank is a US-based custom fabricator of steel pressure vessels, hot water generators, process tanks, and storage tanks, operating continuously since 1898 from a 110,000 sq ft manufacturing campus in Niles, Michigan, with a dedicated 85,000 sq ft Alloy Works facility for specialty stainless steel vessels. The company builds under ASME Boiler and Pressure Vessel Code (Section VIII Division 1 with U, HLW, R, and S stamps), API 620/650, and ASHRAE 90.1b standards, and holds proprietary technology including Ultonium glass lining fused to steel at 1530°F with integrated Microban antimicrobial protection, the patented Diverter Tube sparging system, and Tank Defender epoxy lining. Its product portfolio spans vertical and horizontal water storage tanks (bare and jacketed/insulated), large-volume electric and hybrid water heaters, hot water generators, Power Plate brazed-plate heat exchangers, hydraulic separators, expansion bladder tanks, indirect water heaters for residential and commercial applications, large volume solar tanks, duplex stainless tanks, and general process tanks including air receivers and boiler blowdown tanks.

The company generates revenue primarily through hardware sales of both standard off-the-shelf products (held in inventory for Quick Ship delivery in 4-5 days) and fully custom-engineered vessels, with pricing quote-based and not publicly disclosed. Go-to-market combines a network of 100+ authorized distributors and sales agents across the US and Canada with direct quote requests handled through the company website for custom and large-volume enterprise orders. Customer segments include OEMs and major manufacturers across automotive, compressor and press, chemical and pharmaceutical, HVAC, water filtration, and waste water treatment, plus residential and commercial hydronics end-markets. The company has been a wholly-owned subsidiary of Bradford White Corporation since 2002 and serves international markets including Mexico, Germany, Saudi Arabia, and broader Asian and European regions.
