You Can’t Paint Over Corrosion: Why Chassis Protection Still Matters in Water Trucks

You Can’t Paint Over Corrosion: Why Chassis Protection Still Matters in Water Trucks

(Follow-up to our earlier posts Why Protecting the Chassis Matters More Than Galvanising the Tank and Built for the Long Haul – WT30 Water Tank Range)


The Harsh Truth About Water Truck Corrosion

This photo says it all - corrosion creeping into a chassis rail beneath what might be a perfectly coated water tank.
No matter how well you coat the tank, if the chassis interface isn’t protected, water, dust, and road grime will find their way in.

This is one of the biggest problems in water trucks today.
Importers focus on tank coatings and forget the chassis - the foundation of the truck. Once corrosion starts inside those rails, performance, safety, and service life all suffer.


Why Galvanising Alone Doesn’t Work

A galvanised water tank doesn’t make a water truck corrosion-proof.
Here’s why the industry keeps getting it wrong:

Dissimilar metal contact between zinc-coated tanks and untreated chassis steel.

Water traps that hold moisture under mounting plates.

Poor sealing where metal meets metal.

Limited access for cleaning and mid-life inspection.

Without a complete corrosion control system, these issues shorten the lifespan of even high-end mine-spec or civil-spec water trucks.


The ATT Approach: Design for Longevity, Not Just Looks

At Any Type Trucks, we engineer corrosion protection into every WT30 Water Truck we build.
Our system focuses on prevention, serviceability, and total lifecycle protection.

1. Water Deflection

Our tank subframes and guards are shaped to deflect water away from the chassis, not trap it. Drainage paths and open designs stop debris from collecting and holding moisture.

2. Streamlined Removable Tank Design

Every WT30 tank is designed to be lifted and removed during mid-life maintenance.
That means the chassis can be fully cleaned, inspected, and recoated - keeping the truck structurally sound for another service cycle.

3. Planned Mid-Life Maintenance

We don’t wait for corrosion to win.
Our water truck platforms are built for easy mid-life refurbishment - lift the tank, clean the chassis, and return the unit to service fast.
It’s a smarter way to protect your investment and extend the working life of your fleet.


Built for the Long Haul

Australian fleets operate in some of the harshest environments on earth.
That’s why Any Type Trucks builds durable, serviceable, and corrosion-resistant water trucks - engineered for mine sites, civil projects, and fleet operators who expect reliability year after year.

Because no matter how shiny the tank looks on day one, real protection starts underneath.
