Polyethylene resins include linear high density (HDLPE), cross-linked high density (XLPE) and linear low density (LLDPE) resins.

Poly rainwater tanks have several advantages over the customary steel water tanks. Their seamless construction provides them with greater impact strength and superior resistance to corrosion. These virtually unbreakable water tanks have a longer lifespan than steel tanks, which can rust through and leak. Poly rainwater tanks are fast and easily manufactured.
