CORRUGATED GALVANIZED STEEL
TANK
TEN YEAR WARRANTY
All corrugated steel water storage tanks are
designed to provide many years of service when properly installed and maintained. Please review and follow the installation and maintenance guidelines prior to
filling tank with water.
Installation:
1. Tank should be located on firm, compacted
native soil.
2. Tank should be carefully set on a level
foundation of 3/4" crushed rock, 4-6" deep with a minimum
1 foot radius from tank wall. When seismic design considerations
require anchoring to a concrete
wall or slab, a layer of 1/2" asphalt impregnated fiberboard, between
tank bottom and cement, is
necessary.
3. Use dialectic couplings on all metal piping
connections to tank to prevent possible electrolysis.
4. When attaching electric controls or wires to
your tank--care should be taken to prevent cables and
control mounting brackets from contacting tank. Use insulated brackets
and other nonconductive
materials. Do not use metal anode probes for level control.
Maintenance
1. Water should be changed with fresh water
about every three to six months. It is preferable that water
be circulated as often as possible. Use water for irrigation, cleaning
or other uses, then replenish tank supply with fresh water.
2. If your tank is equipped with an automatic
fill shut-off float valve, periodically check the adjustment
of the float arm attached to the float ball to prevent over flow.
3. If the water supply contains "hard"
or corrosive minerals, tank interior may require periodic cleaning
and recoating. Inspect tank interior and exterior coatings annually,
clean and re-coat if needed. Consult
with your local factory representative for additional recommendations if
necessary. Under normal water
conditions, tank coatings should last the life of the thank (typically 25
years).
To Clean Tank- Wash walls with water and use soft bristle brush to remove rust
and mineral deposits. Rinse with water and dry. Leave the top of the tank off.
To Recoat Tank- Once tank is cleaned and dried, recoat using a large brush.
If it`s a warm day it could take as little as 48 hours to dry. Leave the top of the tank off.

RE: NSF Corrugated Galvanized Steel Water Reservoirs
Corrugated Steel Tanks will provide years of
flawless service. Our corrugated galvanized storage tanks offer tremendous advantages over the options for water storage.
The options available to store water in large capacities are limited. They
are either welded or bolted steel tanks. Welded tanks are typically "butt" welded that rely on a
single weld bead for structural integrity. Certifying the structural quality and penetration of the weld is not
economically feasible for this type of tank construction. Bolted steel tanks rely on rubber gasket joints
that may require periodic servicing for leakage.
Installation
Corrugated field erected tanks are assembled without the need for heavy
equipment or potentially dangerous welding
construction. Corrugated tank components can be trucked in; hand carried
or even dropped in by helicopter. Expert
experienced craftsmen who insure the highest possible construction integrity
fabricate the tanks.
Construction
Corrugated steel has nine (9) times the tensile strength of flat steel
and is superior in resistance to compressive loads. Corrugated steel is especially resistant to the buckling and
"mushrooming" that can affect flat metal tanks during an
earthquake. Corrugated tank seams are overlapped and hand-riveted with
solid steel urethane polymer coated rivets
forming a double thickness of steel that further enhances the lateral and
vertical strength of the tank.
Service
Corrugated galvanized steel tanks have been manufactured in California for
over 100 years. With minimal periodic
maintenance, corrugated water tanks can provide decades of trouble free water
storage.
Safety
Most of American Tank Company`s Corrugated Tanks meet Seismic Zone 4
requirements and conform to Unified
Building Code (UBC) criteria. Set on a wide contained gravel foundation,
the width of the tank provides resistance
to overturning without the need for expensive seismic anchors. If
anchoring is required or requested, American Tank
Company will provide a foundation design and submittal drawings with a
California Civil Engineers wet stamp for building permits upon receipt of purchase order.
Warranty
There is an unprecedented 10 year manufacturer`s warranty against
defects in material or workmanship that cause
either leakage or corrosion.
Date: January 21, 1998
American Tank Co., Inc. has been a supplier of water storage tanks
throughout the United States since 1976. Our Corrugated Galvanized Water Storage Tanks are commonly used for domestic water storage, fire protection and small private water systems.
ATC Corrugated Galvanized Steel Water Storage Tanks are structurally
designed to A.I.S.C. engineering criteria. Tanks can be engineered to meet Seismic Zone 4 design criteria of section 12 of AWWA D-103-87. Our tank
appurtenances can be specified to conform to the accessories requirements of
NFPA-22 and Health Department Requirements for Small Water Systems. Our tank sealant (Sika-Flex 201) is NSF approved for drinking water storage applications.
ATC Corrugated Galvanized Steel Potable Water Tanks are lined on the
inside with NSF Approved Elastomeric Polyurethane coating.
We apply NSF Approved Elastmeric Polyurethane to our
galvanized tanks for the following reasons:
1. Adhesion - NSF Approved Elastmeric
Polyurethane forms a water tight, molecular bond to galvanize without sandblasting. Sandblasting galvanized steel would remove the factory applied zinc coating, removing a valuable Secondary defense against corrosion.
2. Application - NSF Approved Elastmeric Polyurethane
is factory applied to all submerged surfaces in strict conformance with the coating manufacturer`s recommended procedures. Field touch up can be easily performed without imposing health or environmental risks associated with field applied epoxy coatings.
3. Acceptance - NSF Approved Elastmeric Polyurethane is accepted by regulatory agencies for use in water systems including schools, hotels, restaurants, campgrounds and water districts.
