ENGINEERED STORAGEPRODUCTS COMPANY
When Engineered Storage
Products Company entered the
liquid storage market with
glass-fused-to-steel bolted
tanks in the 1970s,
the company already had years
of experience producing glass-
coated tanks for the agricultural
market. Environmental
concerns were creating new
demands for liquid storage
tanks. As this market expanded,
glass-fused-to-steel tanks
proved to be a preferred choice
for many applications. Today,
Aquastore® tanks are found in
virtually every segment of the
liquid storage market, storing
potable water, waste water,
process water, fire suppression
water and landfill leachate.
Glass-fused-to-steel bolted
tanks offer several advantages
that have contributed to their
rapid acceptance. They are cost
effective. Factory coating
eliminates the weather delays
and variables affecting the
quality of field applied coatings.
The unique, bolted lap-joints

can be pre-engineered to allow
for future vertical expansion.
Bolted tanks can be erected in
remote locations and can be
designed for relocation. Best
of all, their performance is
dependable, with minimal
maintenance cost.
The factory-applied silica glass
coating on Aquastore tanks
forms a hard, inert barrier for
both the interior and exterior
surfaces of the tank. It guards the
steel core against weather and
corrosion. The physical proper-
ties of the glass coating
are especially suited to
municipal/industrial
liquid storage applications.
Glass-fused-to-steel is
impermeable to liquids
and vapors, controls
undercutting causedby corrosion and
offers
excellent
impact and abra-
sion resistance. The
color won’t fade or
chalk, and most
graffiti can easily be
removed with paint solvents.
Engineered Storage Products
Company utilizes a variety of
sealants with specific chemical
resistant properties suited to the
range of liquids stored
in different applications.
Engineers at Engineered
Storage Products Company

tions are available for each tank.
Aquastore glass coatings
meet ANSI/NSF Standard 61
requirements for indirect
additives, making our tanks
suitable for potable water
storage. The combination of
bolted construction, glass-
fused-to-steel technology and
custom engineering has given
Aquastore tanks a unique
position in the environ-
mental market. Aquastore
tanks are adaptable to a
wide variety of liquid storage
and waste water process
applications.

Engineered Storage Products
Company’s DeKalb, Illinois
manufacturing plant houses
every stage of Aquastore pro-
duction. From processing of
raw steel, sheet surface prepara-
tion, hole punching and coating
application to packaging and
shipping, everything is accomp-
lished in house. In keeping with
its commitment to maintaining
high standards, our manufac-
turing facility is ISO 9001:2000
quality system certified.
Raw steel that is delivered to
the plant is tested for physical
properties, such as tensile
strength and elongation, and
chemically analyzed. After the
sheets have been cut and
rolled, the radius is checked for
accurate dimensional control.
The heart of the Aquastore
tank coating system is a multi-
step process for glass-fused-to-
steel. The sheets are steel grit
blasted to produce a clean,
rough surface, then inspected
and pre-coated. Borosilicate
glass compositions are ground,
blended with minerals and
clays, then mixed with water to
form a sprayable slurry called
slip. The slip is applied and the
wet film is checked for the proper
coating thickness.
The proprietary formulation of
borosilicate glass and minerals
is fused to the steel sheets at
temperatures above 1500o
Fahrenheit (815.5o C) to produce
the distinctive glossy Aquastore
tank coating. The molten glass
reacts with the steel surface to
form an inert, inorganic system
that is chemically and mechani-
cally bonded to the steel.
Engineered Storage Products’
proprietary Edgecoat™ process
flame sprays the edges with a
protective alloy. Glass is then
added to double coat regular
sheet edges with barrier coatings,
so that standard steel panels are
largely encapsulated in glass. For
some tanks, multiple applications
and firings produce specialized
coatings. Final checks are made
to assure color conformity and
finished coating thickness.
The other components of the
tank are subject to the same
exacting procedures. The bolts
for assembly are fabricated in
DeKalb. Inspection processes
are carried on throughout the
plant, extending to tensile
testing of our bolts and
continuous monitoring
of mechanically-galvanized
bolt coatings and the condition
of plastic bolt head encapsula-
tion. Even the sealant is
inspected on a batch-by-batch
basis. By the time the
Aquastore components are
crated, every part has been
quality confirmed.
Glass-fused-to-steel is
already a proven product.
Engineered Storage Products
continues to develop new
glass coating formulations
for specific functions. Our
Glass97™ interior tank wall
coating is a recent example.
Glass97 is formulated with
titanium dioxide, which
increases coating toughness
for potable water appli-
cations. Our traditional
cobalt blue coating and
Glass97 are both ANSI/NSF
Standard 61 certified for
contact with potable water.
Constant monitoring andtesting throughout thecoating process assures thehighest levels of quality.
State of the art engineer-ing software specificallydeveloped for tankanalysis controls a jobfrom design throughfabrication and erection.
A fully equipped in-house labprovides constant monitoring ofmaterials. Metallurgic testsinclude spectrographic analysis,tensile strength and Rockwellhardness. We monitor color,
thickness and continuity of coatings.Sealants are tested for conformity ona batch basis. Bolts are tested fortensile strength, polypropylenecopolymer encapsulation andmechanical galvanizing.
