This is possible due to its special construction of an inner layer of FDA approved virgin HDPE, two inside layers of PE for improved stability, plus one outer layer of black and UV-stabilized PE.

Not only is it special in terms of its construction, it also has the best warranty the industry has to offer: lifetime corrosion protection and 5 years of labor insurance coverage (see warranty for more details).
