Materials & Manufacturing
Protank’s steel water tanks are manufactured from hot dipped galvanized
steel that resists weathering, corrosion, impacts and is UV proof. The
weight of steel used is either G-115 or G-145 depending on product type
(1.15 to 1.45 ounces per square foot – the thickest advertised coating on
the market). They feature corrugated steel sidewalls made to either 20
gauge or 23 gauge for the largest tank capacities, and 24 gauge to 26 gauge
roof panels.

Our galvanized water tanks have structural dimensions that increase from
130" diameter x 90" height (10.8ft x 7.5ft) up to 512" diameter x 127"
height (42.7ft x 10.6ft).
Tank Features | Available Roof Types
Galvanized steel water tanks come in various roof type options to suit
application needs and location requirements. The tanks are available with
either standard or speciality roof types. Standard roof types include: 30°
Flat Seam Roof, the most commonly used type; 30° High Rib Roof; 10° High
Rib Roof, and; Open Top. Specialty roof types include: Inverted Roof; Flat
Roof; Corrugated Flat Roof, and; Membrane Cover type.
Tank Features | Plumbing
All galvanized steel water tanks feature water flow inlets, outlet access
ports and safety overflow pipes. Tank inlets come in either 16” or 20”
diameters with a roof inlet basket screen and UV guard. Delivery outlets
are 2” standard bulkheads (or 2” GFN type) with a nickel coated ball valve
fitted with a PVC schedule 40 type connector. Tank volume overflows are 6”
PVC pipe overflows with mosquito screen and anti-animal one-way flap
guards.
Tank Liner
Internal steel water tank liners are made from either 20mil polyethylene or
24mil PVC, modern, durable and flexible thermoplastic materials. The resins
used are high quality, BPA free virgin resin only that meets FDA and NSF /
ANSI requirements for food grade, drinking water use.
Polyethylene liners are 20mil thick geomembranes with 700% elongation to
break and 2000min HPOIT per ASTM D638 and D5885 standards, respectively.
Important Points | Installation, Site Preparation, Benefits
When ordered, galvanized steel water tanks are delivered to your direct
location as a complete unassembled package ready to be installed.
Installation occurs onsite by licensed professionals after receipt of a
thorough site specific, structural design calculation package certified by
a licensed engineer within your state. This ensures the tank is built
firmly to location requirements and in compliance with local law
ordinances.
These tanks often require a concrete floor or other foundation type to
provide tank support. Thorough review and the site engineer will design and
specify foundation, anchor types, size and necessary embedment.
Benefits
Galvanized steel water tanks promote water conservation, can be built on
difficult to access sites, can be disassembled, can be relocated, are
suitable for active / passive fire protection systems, can reduce well pump
strain, can increase property value and are capable of lasting a lifetime.
Available Options for Steel Water Tanks
Our galvanized steel water tanks feature various customization options or
add on accessories. They can be installed in various colors from green,
black, white, beige, gray and others to match their surroundings. Tanks can
be made with different side wall types including annular, steel cladding,
patina, wood, decorative facia and masonry type exteriors. Tank walls can
accept signage for the installation of company logos, branding statements
or decals. Available steel water tank accessories include rainwater gutter
systems that use the tank roof to capture rainwater; an external water
level indicator; OSHA compliant side ladder, roof ladder and roof safety
rings; 20” to 30” lockable hinged tank roof manway openings. Tank towers
are also available to provide water tank elevation and come in wood, steel
or in combination with round, square or octagonal platforms with straight
or slanted leg styles.
Six Main Applications and More
Galvanized steel water tanks are ideal for many applications where a repeat
source of reliable water is necessary. Their most common uses are in
rainwater harvesting, fire protection, stormwater management, irrigation,
agriculture, and potable water sourcing. For rainwater harvesting (RWH),
steel water tanks offer the largest volume collection tanks on the market.
In fire protection, they frequently service rural precincts, farms or small
towns with only a small, maybe volunteer type fire department. For
stormwater management, these tanks can help prevent damage or hazards from
insufficient infrastructure and help gain control of weather effects over
large land ownership cases.
In irrigation uses, our steel tanks serve as welcome alternatives to long
draws on well supplies and pumps or from reliance on municipal supply. For
agriculture, they help offset dry seasons, unexpected droughts and provide
water during growing seasons. In potable water provision, the tanks deliver
clean, lasting and certified materials suited for years of drinking water
service to businesses, industries, healthcare, educational facilities,
storefronts, farms and residences.
Our steel water tanks are also often and suitably used as thermal storage
and water cooling tanks as well as brewery and winery tanks.

Fire protection tanks are growing as a cost effective alternative to meet the fire flow demands for residential and commercial developments dictated by local precincts.
Using tanks for detention or retention of stormwater is an effective way to maximize land use while decreasing project costs and is a requirement in many jurisdictions.
Water storage tanks are a great alternative to well water or municipal supply for irrigation watering needs. See how tanks can be utilized in conjunction with traditional methods.
Cisterns and water tanks have been a popular solution for agriculture water needs for decades. Stored water helps to offset the dry seasons providing needed water in the growing season.
Our tanks are available in many sizes and capacities for capturing and safely storing potable drinking water with NSF-61 certified liners for private residence and public venues.
