Benefits of a Polyethylene tank?


Competitively priced

You will find we are more cost-effective than alternative materials like galvanised steel, concrete or stainless steel.

Easy to transport & install

Polyethylene is very cost-effective to transport & install. It does not require heavy equipment to be lifted or moved.

No corrosion or rust

No rust, no corrosion, no lime and no rotting. Our tanks are extremely durable and there is no need to re-paint!

Strength & Longevity

Tanks are designed for strength, with thicker walls at the base. Our tanks have been manufactured for over 20 years!

Easy maintenance

Poly tanks require much less ongoing expense to maintain, and can be setup with a tank self cleaning system.

Variety of shapes & sizes

Polyethylene tanks can be offered in a variety of models, shapes, and sizes, and are great for both above ground and underground use.
Very easy to do business with. Delivery was right on time and the installer was fantastic. I couldn't be happier and will definitely buy from National Poly Industries again.
