Steel Bolted Tanks

Protank offers some of the best steel bolted tanks available on the market today. Our tanks make top choices among water tanks in terms of their construction material, engineering design, volume capacity, available options, customization ability, certification and company support. Our steel bolted water tanks are produced by North America’s leading steel bolted tank manufacturer Climate Inc. with more than 20 years experience, growth and industry know-how on providing quality, reliable water tank products. These large capacity steel bolted water tanks are perfect for scenarios that need a long lasting, compatible and certified source of clean water backed with a leading warranty system. Our steel bolted water tank products are fabricated in the USA with the highest quality raw materials that meet or exceed the requirements for sizable building structures intended to hold large capacities of water. The combination of Climate Inc's high-factory controlled quality with technical support provide clients with a complete engineered storage tank solution for thousands of different industries and applications worldwide.

Climate Incorporated steel bolted tanks Climate Tanks™, FRP tanks, and HDPE tanks are suited for tough environments where dependability is a vital characteristic. They can withstand the extremes of the environment in any urban, rural, or remote location. The modular and custom design principles of our tanks offers ease of transport, reduced erection and assembly timelines and provide project site adaptation with the added values of immersion heaters, insulation kits, and numerous other ancillaries. The bolted nature of the Climate Tanks™ allows them to be built very quickly when compared to welded or concrete structures. It also allows the existing tanks to be unbolted and moved on to new locations when required, significantly increasing asset value. Engineered designs will accommodate secure tank storage for local environmental conditions, such as high wind speeds, snow or seismic loads. The bolted tank and silo system allows structural designs to be used in various configurations including: Firewater, Storing of liquids, ClimaHarvest™ (Stormwater retention & Rainwater harvesting), Drinking water, Bulk material, Process tanks, Agricultural, Anaerobic Digestion & Biogas, Slurry, Mining, & Chemicals.

Steel Bolted Water Tank Specifications

Tank Codes & Certifications

Our steel bolted water tanks are approved with the requirements of relevant tank design standards and applicable International Standards: American Water Works Association (AWWA D103), European Union (EN 10025, EN 10149), American Society for Testing and Materials (ASTM A1011), National Sanitation Foundation (NSF/ANSI/CAN 61), National Fire Protection Association (NFPA 22), Texas Commission on Environmental Quality (TCEQ), and FM Global.


Protank’s steel bolted water tanks come in standard volume capacities ranging from 500 gallons up to 700,000 gallons (1,892 to 2,649,788 liters). Larger capacity tanks can be provided on request.

Tank Features | Roof

Roof is a fixed rigid design consisting of steel decking of ribbed design supported by galvanized Z and C purlins and finished with flashing.

Tank Liner

The tank is lined with a PVC liner that is fixed to the top of the tank through reinforced eyelets. Polyester geotextile matting is placed on the tank floor and walls to protect the liner from damage during installation and use.

Important Points | Installation, Site Preparation, Benefits

When ordered, the tank consists of steel panels and is fixed together with bolts. The steel bolted water tanks are delivered to your direct location as a complete unassembled package ready to be installed. Installation occurs onsite by licensed professionals after receipt of a thorough site specific, structural design calculation package certified by a licensed engineer within your state. This ensures the tank is built firmly to location requirements and in compliance with local law ordinances.

These tanks often require a concrete floor or other foundation type to provide tank support. Thorough review and the site engineer will design and specify foundation, anchor types, size and necessary embedment.


Steel bolted water tanks promote water conservation, can be built on difficult to access sites, can be disassembled, can be relocated, are suitable for active / passive fire protection systems, can reduce well pump strain, can increase property value and are capable of lasting a lifetime.

Available Options for Steel Bolted Water Tanks

Our steel bolted water tanks feature various customization options or add on accessories. Available steel bolted water tank accessories include rainwater gutter systems that use the tank roof to capture rainwater; Halcyon Assembly™; SeeLevel Blue™, an external water level indicator; OSHA compliant side ladder, roof ladder and roof safety rings.

Applications and More

Steel bolted water tanks are ideal for many applications where a repeat source of reliable water is necessary. Their most common uses are in rainwater harvesting, fire protection, stormwater management, irrigation, agriculture, potable water sourcing, mining & fracking, bulk storage, chemical storage, wastewater storage, and process water. For rainwater harvesting (RWH), steel water tanks offer the largest volume collection tanks on the market. In fire protection, they frequently service rural precincts, farms or small towns with only a small, maybe volunteer type fire department. For stormwater management, these tanks can help prevent damage or hazards from insufficient infrastructure and help gain control of weather effects over large land ownership cases.

In irrigation uses, our steel bolted tanks serve as welcome alternatives to long draws on well supplies and pumps or from reliance on municipal supply. For agriculture, they help offset dry seasons, unexpected droughts and provide water during growing seasons. In potable water provision, the tanks deliver clean, lasting and certified materials suited for years of drinking water service to businesses, industries, healthcare, educational facilities, storefronts, farms and residences.

Our steel water tanks are also often and suitably used as thermal storage and water cooling tanks as well as brewery and winery tanks.
