Fusion Bonded Epoxy Tanks: Are They the Modern Solution?
Fusion Bonded Epoxy, or FBE, tanks are engineered for long-term performance. Unlike traditional paint, the FBE coating is a specialised powder fused directly to the steel in a controlled factory environment. This creates a tough, continuous bond that resists chipping and peeling.
How Do FBE Tanks Work?
FBE tanks use an engineered polymer coating. The epoxy powder melts and permanently fuses to the steel, creating a solid and uniform coating that is highly resistant to corrosion and abrasion.
The robust, non-porous surface protects the steel from harsh chemicals and demanding environments, making the tank durable and low maintenance over its service life.
Where Are FBE Tanks Ideal?
FBE tanks are well suited to critical applications where a long-lasting, high-performance storage solution is needed. This includes:
- Potable water
- Wastewater
- Industrial use
- Municipal projects
- Chemical storage where a high-performance, non-porous coating is required
FBE tanks offer excellent corrosion resistance and can handle liquids within a pH range of 3–12.
Which Type of Steel Tank Is Right for Your Project?
Different steel tank systems suit different applications. The right choice depends on your water type, hygiene requirements, corrosion exposure, budget, maintenance expectations and project conditions.
Galvanised Tanks: Why Are They a Proven Choice?
Galvanised tanks are a durable and reliable option for water storage. They are made from steel sheets protected with a zinc coating. This coating acts as a barrier against rust and helps the tank last for many years.
How Does Galvanised Steel Protect the Tank?
Galvanised steel uses sacrificial protection. The zinc coating helps protect the underlying steel from corrosion and is often used with a liner.
Where Are Galvanised Tanks Ideal?
Galvanised tanks are a dependable choice for large-scale, practical applications where durability and cost-effectiveness are important. They are commonly used for:
- Agriculture
- Fire fighting
- General industrial use
- Farming
- Industrial applications
- Fire-fighting applications
Galvanised tanks are a proven, cost-effective and durable tank option.
Zincalume Tanks: Are They a Modern Choice for Water Storage?
Zincalume is a type of steel with a specialised alloy coating made from aluminium, zinc and a small amount of magnesium. This advanced coating gives the steel greater resistance to rust and corrosion than standard galvanised steel.
How Do Zincalume Tanks Work?
Zincalume tanks use a two-part system to store water. The strong Zincalume steel shell protects the outside of the tank from the weather. Inside, a flexible tank liner holds the water so it does not come into contact with the steel. This helps keep the water clean and prevents contamination.
Where Are Zincalume Tanks Ideal?
Zincalume tanks are a popular choice for many projects because of their durability and modern appearance. They are suitable for:
- Residential use
- Rural use
- Fire fighting water storage
GFS Tanks: Are Glass-Fused-to-Steel Tanks the Gold Standard in Durability?
Glass-Fused-to-Steel tanks, also known as GFS or Glass-Lined Steel tanks, use premium coating technology. The process involves heating steel panels to over 800°C and fusing a thin layer of glass to both the inside and outside surfaces.
This creates an inseparable bond between steel and glass, combining the strength of steel with the superior corrosion resistance of glass. The result is a smooth, non-porous surface that will not rust or degrade over time.
Where Are GFS Tanks Ideal?
GFS tanks are a leading choice for critical applications that require long-term durability and low maintenance. They are suitable for:
- Potable water storage
- Wastewater treatment
- Industrial processing
- Applications requiring the longest possible service life
- Projects where minimal maintenance is important
GFS tanks offer excellent corrosion resistance and can handle harsh chemicals.
Stainless Steel Tanks: When Is a Stainless Steel Tank the Premium Solution?
Stainless steel tanks represent a premium option in liquid storage technology. Constructed from high-grade 304 or 316 stainless steel, they offer superior inherent corrosion resistance without requiring internal liners or external coatings.
A stainless steel tank is naturally robust and supports excellent longevity, structural integrity, hygiene and purity.
For high-value projects requiring a stainless steel water tank, stainless steel tank water solution or stainless steel water storage tank, this material is often preferred where cleanliness and corrosion resistance are essential.
Where Are Stainless Steel Tanks Ideal?
Stainless steel is the essential choice for applications where purity, hygiene and extreme durability are non-negotiable. Typical uses include:
- Wineries
- Breweries
- Food and beverage processing
- Pharmaceutical manufacturing
- Potable water storage
- Harsh chemical storage
- High-purity liquid storage
A stainless steel water tank in Melbourne, stainless steel water storage tanks in Geelong or a stainless steel tank in Morwell may be suitable for projects where hygiene, durability and long-term corrosion resistance are key priorities.

Frequently Asked Questions
Steel water tanks can be used for rainwater harvesting, household water supply, garden irrigation, potable water, livestock watering, crop irrigation, stormwater management, process water, fire-fighting reserves and industrial water storage. The correct tank design depends on the type of liquid, required capacity and site conditions.
Yes. Steel water tanks can be designed for both above-ground and underground installation. Depending on the project requirements, a tank may be positioned beneath a driveway, patio or other usable area, making it suitable for compact sites where available space is limited.
The best tank depends on the intended application, water quality, hygiene requirements, corrosion exposure, budget and maintenance expectations. Armstrong Tanks offers galvanised, Zincalume, Fusion Bonded Epoxy, Glass-Fused-to-Steel and stainless steel tank options for different residential, agricultural, commercial and industrial needs.
Yes, steel tanks can be used for potable water when suitable materials, coatings or internal liners are included. Potable water tanks should be designed and manufactured to meet relevant requirements, including AS 4020 for products used in contact with drinking water.
Galvanised steel is protected by a zinc coating that provides sacrificial protection against corrosion. Zincalume uses an alloy coating containing aluminium, zinc and magnesium for enhanced weather and corrosion resistance. Zincalume tanks generally use an internal liner so the stored water does not come into direct contact with the steel shell.
Fusion Bonded Epoxy tanks use a specialised powder coating that is fused directly to the steel in a controlled factory environment. The resulting non-porous surface offers excellent resistance to corrosion, abrasion and chipping. These tanks are commonly used for potable water, wastewater, municipal, industrial and selected chemical storage applications.
Glass-Fused-to-Steel tanks combine the structural strength of steel with the corrosion resistance of glass. The glass coating is permanently fused to the steel panels at high temperatures, creating a smooth and durable surface. These tanks are well suited to potable water, wastewater treatment, industrial processing and projects requiring minimal ongoing maintenance.
Stainless steel tanks are suited to applications where hygiene, purity and high corrosion resistance are essential. They are commonly used by wineries, breweries, food and beverage processors, pharmaceutical facilities and businesses storing potable water, high-purity liquids or corrosive substances. Armstrong Tanks offers options made from high-grade 304 or 316 stainless steel.
Yes. Bolted steel tanks are a practical option for large-capacity water storage because the components can be fabricated in a factory and assembled on-site. They can be used for fire water, potable water, farming, mining, industrial facilities and food industry applications.
The applicable standards depend on the tank design and intended use. Armstrong Tanks references standards including AS 4100 for steel structures, AS 1170 for structural design actions, AS 4680 for galvanised coatings, AS 4020 for potable water and AS 2419.1 for fire hydrant installations. AWWA D103 may also apply to factory-coated bolted steel water tanks.
