Open Top Storage Tank

Our industrial open top (IOT) tanks are molded from your choice of virgin high-density cross-link or NSF-certified linear polyethylene. 

These flat bottom vertical tanks are molded with a stiffening lip on the top to give the tank rigidity, and they are equipped with a shoe-box style cover.

Assmann open top tank covers include a unique design that allows the lid to be hinged and stay open. They are available in a variety of colors and in sizes ranging from 30 to 680 gallons. 

We also offer both stainless steel and mild steel epoxy-coated agitator support stands.
