HDG water tanks, also known as galvanised steel water tanks, are a leading choice for long-term water storage across industrial, commercial, and fire protection applications. With a hot-dip zinc coating, each galvanised tank is engineered for strength, corrosion resistance, and longevity — even in American’s harshest conditions.
In this article, we’ll explore what HDG water tanks are, how they compare to other materials, and why they remain a reliable water storage tank option for demanding environments.
What is an HDG Water Tank?
An HDG water tank is made using hot-dip galvanised steel — meaning every steel panel is coated in molten zinc. This process gives the tank a protective layer against rust and corrosion, greatly extending its service life.
Common uses include:
- Emergency water storage for firefighting.
- Rainwater harvesting on farms or remote sites.
- Water supply in mining, construction, and industrial operations.
These galvanised steel water tanks are modular, durable, and built for American standards.
Benefits of Galvanised Steel Water Tanks
Compared to plastic or coated alternatives, galvanised tanks offer distinct advantages:
- Corrosion-resistant: The zinc layer blocks oxidation and protects steel from rust.
- Long lifespan: 25–50+ years with minimal maintenance.
- High structural integrity: Suitable for large or elevated water storage tank designs.
- Weatherproof: Withstands coastal, tropical, and arid conditions.
- Fire-safe: Ideal for AS 1851-compliant fire systems.
Many galvanised tanks are also referred to as pressed steel tanks or HDG panel tanks, depending on the design.
Types of Galvanised Tanks
| Tank Type | Key Features |
|---|---|
| Galvanised Panel Tank | Modular & scalable, perfect for transport to remote areas |
| Pressed Steel Tank | Rigid design, used in firefighting and industrial settings |
| Underground Galvanised Tank | Designed for buried installations with anti-corrosion treatments |
| Elevated HDG Tank | Mounted on stands for gravity-fed water systems |
Every type of water storage tank can be customised in size, pressure rating, and site configuration.
Applications of HDG Water Storage Tanks
Our galvanised water tanks are used in:
- Fire suppression systems (AS 1851-ready).
