Modular Tanks

HISHITANK Systems

Proven Fire Protection with Engineered Durability

With over 50 years of engineering expertise, HISHITANK™ is a trusted name in fire suppression tank systems across industrial, commercial, and municipal sectors. Each unit is built for long-term reliability in high-stakes environments where safety cannot be compromised.

Constructed from fiberglass-reinforced plastic (FRP) panels, these tanks are designed to resist corrosion, extreme temperatures, and structural fatigue. A robust external steel support frame adds additional strength and stability, while precision-fitted gaskets ensure watertight performance and minimize maintenance needs.

HISHITANK Fiberglass Fire Water Storage Tanks

HISHITANK™ fiberglass tanks, made from high-strength FRP (fiberglass-reinforced plastic), offer superior durability and performance compared to traditional steel or concrete tanks. Engineered for fire protection and potable water applications, these tanks combine longevity, easy assembly, and flexible site integration. Thanks to their modular panel design, HISHITANKS can be installed without cranes or welding. Simply align the panels, place the gasket, and bolt them into place—making the process fast, repeatable, and accessible in remote or confined locations. Unlike round tanks, HISHITANK’s square structure allows for space-efficient installation and a wide range of layout options, maximizing capacity even in constrained environments.

• Easy Construction: Assembling the HISHITANK requires no heavy machinery; simply fix the gasket between panels and join them with bolts for effortless completion.
• Square-Shaped Design: Maximizes space utilization and water storage compared to round tanks, offering versatile design options.
• Performance: HISHITANK holds compliance in NFPA and NSF, ensuring quality and suitability for beverage storage.
• Modular Flexibility: Available in various shapes such as T-shape and H-shape, ranging from 265 to 320,000 US gallons, adaptable to different property structures.
• Retrofit Capability: Ideal for renovating existing buildings, HISHITANK can be installed in narrow entrances or rooms, accommodating diverse installation scenarios.
• Easy Maintenance: Requires no internal coating or rubberizing, simplifying cleaning and maintenance compared to tanks made of other materials.
