Steel Core takes pride in the fact that all of their steel has a minimum recycled content of 50% or greater and is sourced from Small family owned mills in the US, and all of their US manufacturing is US-Based using skilled US Labor.
Steel Core is the premiere manufacturer of Corrugated Bolted Steel Tanks ranging from 1000 to 650,000 gallons.
Steel Core was built from the ground up. Steel Core began as installers, and those years of hands-on experience lead them to see that improvements could be made in terms of materials, appurtenances, liners, and ease of tank assembly.
When Steel Core turned into manufacturers they took their experience on the job site to the drawing board and then onto the factory floor. Steel Core considers all aspects of a tank from its use, to its easy of assembly, to how the tank itself is shipped to you.
Steel Core has use applications in Fire Protection, Potable Water, Wastewater, Irrigation Water, Agricultural Water, Rainwater & Stormwater, Chemicals, Oil, and Temporary Storage.
Steel Core has the strongest “Green Manufacturing” principles and practices in the industry, and their tanks have been certified through the rigorous performance standards of the Living Build Challenge. (really?)
Steel Core Tank
STEEL CORE TANKS
Steel Core uses a Dual-Liner System, foremost to protect the water inside the tank, but also to protect the steel to ensure long life. The Water in a Steel Core Corrugated Bolted Steel Tank NEVER touches the Steel!
Steel Core uses Liners designed specifically for each individual tank, heat welded prior to shipping, arriving ready to install. We can even use a Center Pole for roof support on some of our extra wide tank diameters (35ft.-72ft.) without causing any issues for our Liners.
Steel Core uses the first liner in their Dual-Liner System, a Flexible Membrane Liner, to hold the water. These Liners are available in 20 mil. PE – 30 mil. PE – 40 mil. PE – 45 mil PP – XR3-PW – XR5 (BPA-Free ?) – Specialty Liners. They can hold everything from Potable (Drinking) Water to Wastewater, the choice of liner being based on your tank application.
Steel Core uses the second liner in their Dual-Liner System, a Geo-Text “Wick-Away” Pre-liner, to pull any condensation off of the tank roof and walls drawing it into the fabric itself. Gravity then pulls that water to the ground, allowing the water to flow out and escape.
Steel Core knows “WATER & STEEL DO NOT MIX” – Since the water is contained within the first liner, it never touches the steel, so there is no chance for corrosion in this manner.
Other corrugated tank companies don’t use LINERS. The water inside their tanks has constant and direct contact with the steel tank walls, and the seams between the panels.
Other corrugated tank companies depend on epoxy interior coatings over the steel, and mastic between seams to stop their tanks from leaking. The problem with that is steel expands and contracts with changes in temperature, epoxy & mastic do not. Epoxy & Mastic crack, and cracks always get bigger. Water seeps through these cracks, and the steel rusts.
That is why Steel Core can offer their Maintenance-Free 10 & 20 Year Warranty. Have a look at the pictures below to see a Steel Core Tank Interior and Another corrugated tank company’s tank interior

Steel Core uses 1.5 inch Grade-8 Galvanized Bolts with Cone Washers to grab and snug against any hole. We also use Grade-8 Galvanized Serrated Nuts for greater grab upon the G115 Steel Panels. All our bolt heads utilize “Allen” Drivers for greater grab & safety.

Steel Core Tanks quoted from National Storage Tank always include the following.
Materials – Appurtenances – Delivery – Engineering (foundation design as well?) – Installation
Also, we do not want to issue change orders, ever. We want you to know the total cost upfront. Each tank is specifically engineered for each project, nothing is ever “off the shelf”.
The only thing we do not include is the foundation or slab due to seismic requirements varying from region to region. We can pour you a slab, or you can use your own contractors.
A note about slabs, changes in NFPA-22 state ALL Fire Protection Tanks over 4,000 gallons MUST be seismically anchored on a Concrete Ring at the very least if not a slab. At National Storage Tank we pride ourselves on knowing the laws & code that pertain to our industry and keeping abreast of any changes.
Other corrugated tank companies … well we encourage you to get a quote from them then ask them if that quote includes Materials, Appurtenances, Delivery, Engineering, & Installation.
Some other tank companies make their money with “CHANGE ORDERS”. Your quote is for the Tank only, then once you sign a binding agreement you realize they did not include Appurtenances or Engineering, Delivery or Installation… then come the change orders…. So, make sure when dealing with another corrugated tank
STEEL CORE TANKS
No other tank company even comes close to Steel Core’s belief in and adherence to Green Manufacturing Principles.
Steel Core Tank’s Director of Development was involved in industrial manufacturing for over a decade, and when he was asked to collaborate with the tank installers-builders who founded the Steel Core brand, he saw an opportunity to create a truly “Green” and “Principled” form of manufacturing that benefited the environment, the company, but most of all the customer.
From Steel Core’s use of a Minimum 50% Recycled Content in all their Steel, to their Zero Waste – At Source Recycling Program, Steel Core raises the bar on the industry, but didn’t stop there. They have a Comprehensive Powder-Coating Overspray Recovery and Recycling System and State Of The Art Ventilation at their facilities, Centralized Distribution to keep the carbon foot print down and Steel Core’s Two-Way Logistics Program delivery trucks carry dedicated loads of cargo on their return trips and deliver that cargo to points along the route back to the factory.

There are many more reasons why Steel Core Corrugated Bolted Steel Tanks are superior to any other tank in the market including being Made in the USA, Installed by Factory Trained Technicians, and able to meet Seismic & Wind Requirements in California and all other States.
We want to stress this point: Any quote you receive from National Storage Tank for a Steel Core Tank includes: Materials – Appurtenances – Delivery – Engineering – Construction. No one else in our industry can claim that distinction.
