With so many commercial liquid storage tanks available, choosing the right one for your needs can be challenging. Comparing features and benefits isn’t always straightforward.
Manufacturers build HDG tanks by dipping solid steel panels into molten zinc to ensure maximum protection. This process creates a durable, corrosion-resistant coating known as hot-dip galvanising.
The result is a tough, long-lasting surface that resists rust and safely stores a wide range of liquids for years. Â
 
															HDG panel tanks safely store potable and fire water, even in tough environmental conditions. Their modular design allows custom sizing to suit any project.

Raven Tanks delivers hot dip galvanized steel panel tanks built to last and tailored to your site.Â
We know our clients often have important questions before starting a project. Here are clear answers to help you make informed decisions with confidence. Â
Hot dipped galvanized hdg protects steel by forming a durable bond between zinc and the steel surface. Zinc acts as both a barrier and sacrificial layer, corroding before the steel to prevent rust, even when scratched. Â Â
Galvanized steel can last 25 to 75 years underground, depending on soil conditions, moisture levels, and coating thickness. In most Australian conditions, HDG tanks last long with minimal maintenance—even underground.
Use paint on galvanized steel to boost its lifespan or align with design specifications. However, surface preparation and compatible primers are critical to ensure proper adhesion to the zinc layer.
Welding galvanized steel works, but only with proper precautions in place. Zinc fumes are hazardous when heated, so proper ventilation and PPE are essential. Reduce the risk by welding first—then apply the galvanised layer.
