Electronic Rust Protection — Backed by Real-World Experience

CAT electronic rust protection systems are used across automotive, industrial and commercial environments where corrosion management matters.

Designed for practical installation and long-term operation, CAT systems provide continuous electronic corrosion suppression that complements conventional coatings and treatments.

Whether installed by vehicle owners, workshops, or commercial operators, the goal remains the same — supporting corrosion management in environments where moisture, salt and contaminants accelerate deterioration.

CAT systems are distributed throughout Australia and supported by a nationwide stockist network.

Choose Your CAT System

Selecting the right system is straightforward — system size is determined by operating environment and exposure level.

I did an 8 pad system on a shipping container pond and all pretty straight forward with instructions and advice given. Expanded it to 10 pads and the additional stuff showed up just about the next day. This system is very easy to work with.
