When it comes to aquaculture tanks, nobody gives as much attention to detail as Polytank:

Our rotomoulding process uses hollow metal moulds and a powdered polyethylene plastic that becomes liquid under high heat. The moulds with the liquid plastic inside are spun on both vertical and horizontal axis to form a uniform thickness, or skin on the outside walls, thus the namecrotomoulding. the mould is removed from head and allowed to cool under controlled conditions to avoid shrinkage or warpage. The resulting polyethylene plastic is resistant to impact, most corrosive chemicals and temperature extremes. The slippery surface makes it very easy to clean. Polyethylene is also environmentally friendly because it can be recycled.

Most Polytank products are one-piece with no seams or sharp edges. The lightweight of polyethylene makes even large units easy to lift and move.

PolyDome, our sister agricultural division, has its own metal fabricating shop from frames, stands, and supports, all of which can be used with our aquaculture line of products. All metal parts are powder coated for corrosion resistance.

Polytank has dealers across the United States, Canada and 10 foreign countries.
