Fisher Tank Company: US Welded Steel Tank Builder 2026

Fisher Tank Company has designed, fabricated and erected field-erected welded steel storage tanks since 1948 — making it one of the longest-established tank constructors in the United States. Operating from fabrication facilities in Chester, Pennsylvania and Leesville, South Carolina, Fisher Tank Company serves bulk liquid terminals, refineries, chemical plants, power generators and municipal water utilities across North America.

Fisher Tank Company Overview

Founded during the early years of the Northeast oil and gas boom, Fisher Tank Company has remained focused on a single discipline: welded steel above ground storage tanks (ASTs). The company is 100% employee-owned under an Employee Stock Ownership Plan (ESOP), a structure that extends ownership to every non-union employee on its payroll. Headquartered at 3131 West 4th Street, Chester, PA, Fisher Tank operates sixteen dedicated construction crews and two state-of-the-art fabrication shops.

Fisher Tank Company builds to API 650, API 620, API 653, AWWA D-100, NFPA and ASME Section VIII Division 1 standards — covering the full range of tank types from atmospheric storage through low-pressure vessels. The company holds ISNetworld membership (#400-129971) and classifies as a Small Business Enterprise (SBE). Its safety record is consistently strong: OSHA TRIR/LTIR figures of 0/0 for both 2021 and 2022 reflect the company’s formal Health and Safety Programme, which operates under a dedicated Director of Safety.

Key Services and Capabilities

Fisher Tank Company provides end-to-end tank solutions: engineering and design, in-house fabrication, field erection, field painting, and ongoing maintenance and repair under API 653. Its two fabrication shops — totalling over 55,000 sq. ft. of floor space — handle plate rolling, beveling, cutting and custom fabrication of tank appurtenances including platforms, stairways, manways and bridges.

The company’s API 653 repair and modification capability is a core part of its business. Fisher Tank works with existing tank farms to extend asset life through bottom replacements, secondary bottoms, liner and leak detection installations, and full shell and roof replacements. ASME pressure vessel repair work (Section VIII Division 1 “U” and “R” stamps) is handled out of the Chester facility.

Tank size range runs from 20,000 gallons to 10 million gallons, in both carbon and stainless steel. Fisher Tank Company builds individual tanks and complete tank farms, offering turnkey packages that include site preparation, foundations, cathodic protection, painting, linings, insulation and instrumentation. This breadth of in-house capability positions Fisher Tank among the more self-contained welded tank constructors in the North American EPC market.

Industries and End Markets Served

Fisher Tank Company’s client base spans a wide range of storage-intensive industries. In the oil and gas sector, the company constructs crude tanks, firewater tanks, fuel oil tanks and ammonia tanks for terminals, pipelines and refineries. Its chemicals portfolio includes work for major names including BASF, DuPont, Chevron Phillips Chemical, Eastman Chemical, Merck and Mosaic Fertilizer — reflecting strong penetration across process industries where material compatibility and containment standards are demanding.

Power generation is a growing segment: Fisher Tank builds Thermal Energy Storage (TES) tanks with custom-fabricated internal diffuser systems for data centres, combined heat and power (CHP) facilities, hospital systems and municipal peak-shaving applications. This positions the company to capture demand as data centre construction accelerates and energy storage requirements grow alongside it.

Municipal water storage remains a core market. Fisher Tank constructs welded steel standpipes, ground storage tanks and reservoirs to AWWA D-100 standards for utilities of all sizes. Welded steel is the only tank type governed by a zero-leakage standard — a specification point the company consistently uses in its client communications. The company also serves ethanol and renewable fuels, aviation and rail, and pulp and paper sectors, making it one of the more diversified welded tank constructors among North American specialists. For an overview of the broader global tank terminal market, the sector context in 2026 reflects sustained capital investment across all of these end markets.

Fisher Tank Company in the North American Market

Fisher Tank Company competes in a market dominated by larger integrated EPC contractors such as CB&I and Tarsco (TF Warren Group), both of which operate at significantly larger scale with international project reach. Fisher Tank’s competitive position is built on depth of specialist expertise, employee ownership culture, and a strong safety record — differentiators that resonate with procurement managers at mid-size terminal operators, refiners and chemical producers where relationship continuity and project-level accountability matter.

The company participates actively in industry bodies covering the welded tank sector, including NISTM, STI/SPFA and AWWA — maintaining visibility with the engineering and operations professionals who specify tank construction contracts. Its consistent presence at NISTM — the primary conference for aboveground storage tank management in the US — reflects a deliberate account development strategy in the terminal and refinery maintenance market.
