VITRIUM is our proprietary titanium Dioxide (TiO2) glassing process applied in a 3-coat, 1-fire (3c1f) process procedure. VITRIUM coating is also produced in a 3-coat, 2-fire (3c2f) process primarily when special colors are requested or thicker layers of glass are required.
The CST proprietary VITRIUM glass-fused-to-steel process provides:
The combination of glass quality and glass thickness provide the assurance that over 69 years of experience and over 100,000 structures successfully installed around the world will continue with each and every new structure installed.
Titanium Dioxide (TiO2)
In CST, formerly Engineered Storage Products, launched an R&D project to develop a process for the direct application of our proprietary Titanium Dioxide (TiO2) Glass. The result is a totally new, patented “3-coat, 1-fire” (3c1f) process for applying TiO2 Glass.
TiO2 is a very common ingredient used by many coating manufacturers for various reasons:
As a result of using higher amounts of TiO2 in the final white layer, a unique visual marker on the glass known as “VITRIUM threading” becomes apparent. This is caused by thicker areas of the top white layer interspersed with thinner areas allowing the underlying bluecoat to show through opaquely. This immediately identifies the coating as VITRIUM.

CST (formerly A.O. Smith) first discovered the methodology of controlling corrosion by fusing glass to steel in the s. The technology was initially used in the brewing and hot water heater industries. While other uses for glass-fused-to-steel were explored, the first glass-fused-to-steel tank went into service in as a HARVESTORE silo. This agricultural use to store feed while retaining quality has been widely used for almost 69 years.
In the s, our Municipal and Industrial Division was formed and we subsequently launched AQUASTORE tanks for water, wastewater and other industrial liquid uses. Since , more than 100,000 AQUASTORE, HARVESTORE, SLURRYSTORE and NUSTRISTORE glass-fused-to-steel tanks have been installed in over 70 countries around the world.
In the realm of storage solutions, glass lined tanks have emerged as a powerhouse, providing durability, resilience, and performance that few other types can match. Also known as glass lined steel tanks or glass lined water tanks, these storage vessels are known for their superior features and versatility.
Crafted from a fusion of carbon steel and glass lining, glass lined tanks ingeniously combine the best of both worlds. The rugged strength of steel and the corrosion-resistance of glass lining culminate in a storage solution that performs well under diverse conditions. This unique fusion lends an edge to lined tanks over traditional storage tanks made of stainless steel or carbon steel.
Compliance with ISO , the international standard for vitreous and porcelain enamels, reinforces the credibility of glass lining and guarantees its performance. The glass lining or vitrification process imparts these tanks the versatility to serve a range of applications, from potable water storage to hot water storage and wastewater treatment.
Glass lined steel tanks are suitable for multiple industrial applications due to their robustness and resilience. In the realm of wastewater treatment, the corrosion-resistant nature of these tanks proves advantageous, allowing for safe and secure containment of waste materials. Moreover, their ability to withstand a variety of conditions makes them an ideal choice for bolted tank construction, a method involving individual steel panels bolted together to create a larger storage unit.
Besides wastewater management, glass lined tanks are a preferred choice for hot water storage, potable water storage, and even in the brewing and fermentation industries. The tanks’ glass fused to steel design ensures the stored materials are kept in optimal conditions, maintaining their quality and integrity.
Despite the many advantages of glass lining, it’s important to note that no glass lining is entirely flawless. Over time, the occurrence of microscopic cracks or pinholes is common, leading to potential corrosion of the underlying steel. This poses a significant challenge as it undermines the tank’s durability and longevity.
Yet, there’s a solution to this predicament: Corro-Protec’s powered anode rods. These rods, engineered explicitly for lined tanks, can drastically extend your glass lined tank’s lifespan, offering effective protection against corrosion and negating the need for routine maintenance.
The working principle of Corro-Protec anode rods is quite simple yet effective. These rods release a small, controlled amount of current into the tank, neutralizing the electrochemical reactions that lead to corrosion. This innovative approach ensures your glass lined steel tank’s longevity, irrespective of its purpose or size.
Interestingly, these anode rods are suitable not only for glass lined water tanks but also for bolted tanks. By utilizing Corro-Protec anode rods, bolted tank structures, along with other types of glass lined steel tanks, can significantly increase their resilience and reliability.
When you need a storage solution for potable water, hot water, or wastewater treatment, lined tanks present a dependable choice. However, it’s essential to acknowledge that every storage vessel, even the robust glass lined steel tanks, can be prone to corrosion over time. Thanks to Corro-Protec powered anode rods, you can extend the lifespan of your tank, eliminate routine maintenance worries, and enjoy peace of mind.
In essence, the resilience and adaptability of glass lined tanks have made them a popular choice in various industries. While they are not entirely impervious to corrosion, with the right corrosion protection in the form of Corro-Protec anode rods, these tanks can promise you enduring performance and reliable service. So when it comes to choosing storage tanks, consider the glass lined steel option for their unparalleled performance and longevity.
