the North American market.

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.

Manufacturing Excellence

CST's DeKalb facility is ISO 9001:2008 quality system certified. Engineers design tanks for a wide range of standards including AWWA D103

Standard for Bolted Steel Water Storage Tanks, AISC, FM codes and NFPA Standard 22. Additionally, glass coatings meet ANSI/NSF Standard

61 requirements for indirect additives, making Aquastore, Harvestore and Slurrystore tanks ideal for liquid, feed, manure storage and digestrate

processes. Most importantly, extreme pride is taken in craftsmanship for a tank that endures the test of time.

From the automated manufacturing processes through the stage-by-stage inspection and even down to careful inspection of the glass. Our

glass-fused-to-steel quality is the best in the industry. The best proof of the precision of CST's manufacturing procedures can be seen in the

thousands of tank installations around the world.

Glass-Fused-To-Steel Process

Glass-fused-to-steel is the premium technology in the tank market. The factory-applied silica glass coating on Aquastore, Harvestore and

Slurrystore tanks forms a hard, inert barrier for both the interior and exterior tank surfaces to guard against weather and corrosion. Glass-fused-

to-steel is impermeable to liquids and vapors, controls undercutting caused by corrosion and offers excellent impact and abrasion resistance. The

color won't fade or chalk and most graffiti can easily be removed. It never needs painting.

A multi-step process is the heart of the glass-fused-to-steel technology system.

Fabricated sheets are grit blasted to a uniform, near white surface

Proprietary formulations of borosilicate, minerals, water and clays are blended into a sprayable slurry called

"slip"

After inspection, the slurry is fused to the steel sheets at temperatures above 1,500 F to produce the

distinctive glossy Aquastore finish

The molten glass reacts with the profiled steel surface to form an inert, inorganic chemical and mechanical

bond

Vitrium Glass Finish

New process technology has resulted in the development of ESPC's newest glass innovation Vitrium.

This coating combines the outstanding chemical and physical resistant properties of Titanium Dioxide (TiO2) saturated glass with a highly

engineered ultra-fine glass structure surface to create a high performance glass-fused-to-steel technology. Vitrium features and benefits include:

Tough TiO2 glass formulations provide longer life

Electrostatic base coat application ensures consistent quality

Maximum coating effectiveness without requiring increased coating thicknessUnique process technologies provide factory certified "holiday-free" sheets

Process efficiencies lead to competitive pricing

Ideal for both cold and hot climates

Edgecoat

CST's proprietary Edgecoat process thermal sprays the glass-fused-to-steel edges with a protective alloy. Glass is

added to double coat the sheet edges with barrier coatings for maximum protection, much like an encapsulated shell.

For some individual circumstances, multiple glass applications and firings produce specialized unique performance

requirements.

Color Options

Aquastore glass coatings are available in standard cobalt blue or four other premium exterior colors. Forest green, sky blue, desert tan or white

premium colors are available at an additional cost. Inquire for custom colors.

History of Glass-Fused-To-Steel

CST Storage (formerly A.O. Smith) first discovered the methodology of controlling corrosion by fusing glass to steel in the 1930s. 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 1949 as a Harvestore silo. This agricultural use to store feed while retaining quality has been widely used for

almost 60 years.

In the 1970s, our Municipal and Industrial Division was formed and we subsequently launched Aquastore tanks for water, wastewater and other

industrial liquid uses. Since 1930, more than 100,000 Aquastore, Harvestore, Slurrystore and NutriStore glass-fused-to-steel tanks have been

installed in over 70 countries around the world.
