Polyethylene tanks now dominate the Australian water tank market as
they are lighter and more cost effective than alternative materials.
The food grade material used in manufacture ensures pure drinking water
with no taint.
All National Poly Industries tanks are manufactured to Australian
Standard 2070 for Food Contact and Australian Standard 4020 for
Drinking Water.
While using quality materials is important, it’s the manufacturing process that makes us stand out from the rest.
Our advanced manufacturing process uses computer-controlled rotational
moulding machines to produce one-piece tanks with extra strength.
Our tanks do NOT have a vertical side seam and do NOT require a pole to support the roof.
The material weight of every tank is stated in writing, giving you
proof of the strength and integrity of every tank manufactured by
National Poly Industries.
National Poly Industries water tanks have:
20 Year Warranty.
Tanks are designed for strength, with thicker walls at the base
One-piece tank construction (with no vertical seams)
100% UV protection against harsh Australian conditions
Every tank has a self-supporting roof (with no internal poles)
Tanks made from food grade material (to Australian Standards AS2070/AS4020)
Delivery is available throughout Queensland, New South Wales and the ACT.
The
manufacturing process of our rainwater tanks has minimal impact on the
environment as there are no emissions during manufacture and the
material can be recycled.
