CST's reputation as the world leader in factory coated tanks goes beyond just field-assembled tanks. CST Storage also manufactures factory coated welded tanks. Unlike field welded and painted tanks, CST welded tanks are fabricated in a modern, indoor, controlled environment.
Once fabricated the tank is cleaned, coated and cured in our oven on a specially designed, controlled processing line. We call this the OptiBond™ coating process, and we are the only company in the world that uses this process to guarantee the best quality coatings for longer life and better life cycle costs.
CST's coatings feature a high cross-linked epoxy with excellent resistance to corrosion. These coatings provide superior immersion qualities and dramatically reduce life cycle maintenance costs. This makes our factory-applied coatings far superior to field-welded tanks.
In addition to factory coated steel tanks, CST fabricates tanks from stainless steel and aluminum. Tanks can be constructed with flat bottoms, with hopper bottoms and with elevated structures. Standard one-piece designs are available up to 85 x 15 that can be fabricated in a matter of weeks. Custom and multi-piece tanks can also be designed and fabricated in larger sizes.
Globally Delivered Locally Supported Tanks
So why ship a tank from our facility in Winchester, TN around the world? One answer is quality. Our global customers have long recognized the value of quality and consistency in their products and processes around the world. Couple that with CST's unique ability to integrate customer specified components in the tank and test them before the tank ever ships and you've got world class savings. Can your other local suppliers provide this service, quality and overall savings?
Unsurpassed Quality, Exceptional Performance
CST operates ISO 9001-certified facilities and employs only ASME-qualified welders. From engineering to in-shop fabrication to component installation, our focus is on providing products and workmanship that will lead to exceptional performance. CST's welded tanks are fabricated to domestic, international and API 12F standards and then shipped around the world.
The Unrivaled Value of Experience
With more than 100 years of experience, CST has produced and installed 250,000 tanks around the world. Applications include:
- Treating water used in the oil-sand extraction process
- Storing powder-activated carbon and Trona used to remove mercury from water
- Desulphurizing flue gases in fossil-fuel-burning facilities, such as coal-fired power plants
Our engineers serve on multiple national committees, setting standards and advising other groups on specifications that have proved superior across a wide variety of uses. This engineering expertise and professional involvement translates into tank systems that meet or exceed industry standards, regardless of the application.

CST's welded silos are ideal for the following applications:
Welded tanks are commonly used in dry bulk applications.
Dry and liquid chemicals present tough challenges for storage tanks. CST's flexibility of manufacturing welded tanks of a variety of materials and coatings puts us in the unique position of being able to provide you the right tank for your application.
Whether just a silo or a silo completely integrated with customer specified equipment, CST is capable of manufacturing and delivering the complete solution anywhere in the world.
Many of the strict sanitary specifications for food storage vessels require the use of a welded tank. When this is the case, factory-welded and factory-coated tanks offer the best coatings and fastest delivery due to the elimination of potential environment conditions that can delay field welded tank construction and coatings.
Factory welded tanks have been a common storage design in oil field applications for over a hundred years. CST has been in business that long and understands the unique needs the oil field demands for welded tanks.
Welded tanks are well suited for small volume storage of fly ash, activated carbon and Trona where the capacity of a bolted tank is not required.
Welded tanks meet the needs of many unique applications on a regular basis. If the need is for a smaller tank capacity and quality and delivery are important, then CST has a welded tank that may meet the needs of the application
