Features Fusion Bonded Epoxy (FBE) Tanks Galvanised Tanks Glass-Fused-to-Steel (GFS) Tanks Stainless Steel Tanks
Material Steel panels With Epoxy coating Steel hot-dipped in molten zinc. Steel panels with a factory-fused glass coating on both sides. Stainless Steel (typically Grade 304 or 316)
Technology Barrier Protection: The epoxy creates a durable, non-porous barrier that prevents corrosion. Sacrificial Protection: The zinc coating sacrifices itself to protect the steel from corrosion. Often used with a liner. Fused Barrier: Glass is chemically bonded to the steel at high temperatures, creating an inseparable, inert barrier. Inherent Resistance: The material itself (chromium-nickel alloy) is naturally corrosion-resistant. No coating or liner is needed
Durability Excellent. Good Excellent Superior
Key Advantage Excellent corrosion resistance and can handle liquids from PH range 3-12 Fire Tanks with competetive price Excellent corrosion and can handle harsh  chemicals The most hygienic option; superior corrosion resistance; and ideal for food-grade and high-purity liquids.
Ideal for Municipal and industrial projects, wastewater treatment, and chemical storage where a high-performance, non-porous coating is required. Agricultural, industrial, and fire-fighting applications where a proven, cost-effective, and durable tank is needed. Portable water storage, wastewater treatment, and industrial applications requiring the longest possible service life and minimal maintenance.

Fusion Bonded Epoxy (FBE) Tanks: The Modern Solution

Fusion Bonded Epoxy (FBE) tanks are engineered to last. Unlike traditional paint, our FBE coating is a specialized powder that’s fused directly to the steel in a controlled factory environment. This creates a tough, continuous bond that won’t chip or peel.

How They Work

  • An Engineered Polymer Coating: The epoxy powder melts
    and permanently fuses to the steel, creating a solid, uniform
    coating that’s highly resistant to corrosion and abrasion.
  • Built to Last: This robust, non-porous surface protects the
    steel from harsh chemicals and environments, making the tank
    exceptionally durable and low maintenance over its lifetime.

Ideal Applications

  • FBE tanks are the dependable choice for critical applications
    where a long-lasting, high-performance solution is essential
    This includes potable water, wastewater, and industrial use.

Galvanised Tanks: The Proven Choice

Galvanised tanks are a durable and reliable option for water
storage. They are made from steel sheets that are protected
with a zinc coating. This coating acts as a strong barrier
against rust, ensuring the tank lasts for many years.

Ideal Applications

Galvanised tanks are the dependable choice for large-scale,
practical applications where durability and cost-ilffectiveness
are key. This includes agriculture, fire fighting, and general
industrial use.

GFS Tanks

GFS Tanks: The Gold Standard in Durability

Glass-Fused-to-Steel (GFS), also known as Glass-Lined Steel
(GLS), is a premium tank coating technology. This 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 the two materials,
combining the strength of steel with the superior corrosion
resistance of glass. The result is a smooth, non-porous surface
that won’t rust or degrade over time.

Ideal Applications

GFS tanks are the leading choice for critical applications that
require the highest level of long-term durability. This includes
potable water, wastewater, and industrial processing where a
low-maintenance, reliable solution is essential.

Stainless Steel Tanks: The Premium Solution

Stainless Steel tanks represent the gold standard in liquid storage technology. Constructed from high-grade 304 or 316 steel, they offer superior inherent corrosion resistance without the need for internal liners or external coatings. This naturally robust material ensures unparalleled longevity and structural integrity.

Ideal Applications

Stainless steel is the essential choice for high-value applications where purity, hygiene, and extreme durability are non-negotiable. This includes wineries, breweries, food and beverage processing, pharmaceutical manufacturing, and harsh chemical storage.

02
Zincalume Tanks: The Modern Choice

Zincalume is a type of steel with a specialized alloy coating of aluminum, zinc, and a small amount of magnesium. This advanced coating makes the steel much more resistant to rust and corrosion than standard galvanized steel.

03

How They Work

Zincalume tanks use a two-part system to store water. The strong Zincalume steel shell on the outside protects against the weather. Inside, a flexible tank liner holds the water, ensuring it never touches the steel. This keeps the water clean and prevents contamination.

Ideal Applications

Zincalume tanks are a popular choice for many projects due to their durability and modern aesthetic. They are perfect for residential, rural, and fire fighting use.
