International Tank Service

What International Tank Service does

International Tank Service, Inc. (ITS) is a privately held, family-owned industrial fabrication and field-construction contractor headquartered in Lima, Ohio, founded in 1977 and currently in its fourth generation of ownership. The company designs, fabricates, and field-erects custom welded aboveground storage tanks to API 650, AWWA D100, and related standards, with capacities ranging from 30,000 gallons to 7,000,000 gallons. ITS serves industrial, commercial, and municipal customers across the United States — including Fortune 100 firms — across a diversified vertical mix spanning petroleum and crude oil, asphalt terminals, liquid fertilizer (UAN), acids and alkalis, frac water, biodiesel/ethanol, brine water, vegetable oil, DEF, fire water, and wastewater/clarifier/digesters. The company supports the full tank lifecycle through complementary services: API 653 inspection, repair and 24-hour emergency service, floating-roof fabrication and installation, proprietary tank jacking and leveling, and manway kit fabrication.

ITS operates an in-house, capital-intensive fabrication footprint in Lima, Ohio, spanning four owned facilities (headquarters at 1085 South Metcalf Street, a dedicated fabrication facility on South Central Avenue, and two operations/warehouse sites) equipped with a Bertsch plate roll, a King vertical turret lathe, Burny 10 CNC plasma tables, CNC water-table burn tables, and multiple overhead bridge cranes (5-ton, 6-ton, and two 10-ton units). Quality and compliance are central to the operating model: ITS holds API 650/653/620, AWWA D100, NFPA, ASME, annual Factory Mutual, OSHA, and USEPA conformance, with in-house licensed API 653 inspectors, x-ray-certified welders, and Professional Engineer-reviewed inspection reports. NDE capabilities include Magnetic Flux Leakage (MFL) floor and edge scans, ultrasonic thickness testing, and magnetic particle, penetrant, vacuum box, and eddy current inspection.

The business model is project-based, custom-engineered, and quote-driven: each engagement flows through a detailed online RFQ capturing diameter, height, capacity, design basis, product stored, materials, fittings, and labor regime (union/non-union/prevailing wage), with both budget and firm pricing options. Revenue mixes one-time new-tank construction with recurring professional services (inspection, repair, emergency response, jacking, and component fabrication). Go-to-market is enterprise field sales — direct-to-customer bidding on custom projects — supplemented by industry association memberships (NAPA, The Asphalt Institute, AEMA) and compliance platforms (ISNetworld, PEC Premier). Customer concentration centers on U.S. enterprise accounts in petroleum and asphalt, with a long tail across adjacent industrial verticals; the firm self-reports 500+ aboveground tanks delivered since 1977 and 330+ fire water tanks.
