Hallsten Aluminum Covers provide gaseous emissions containment for clarifiers, sludge holding tanks, aeration basins and any number of other storage vessels found in projects of environmental importance.

Our continuing design effort has resulted in over a dozen US Patents. These patents not only include the primary structural design but also many of the unique features found only on our cover system. Among these features are the Gear Hinged Access Hatch Panel and the Double Gutter Seal. The Gear Hinged Access Panel allows any individual panel on a cover system to become a fully opening and latchable access hatch. This effectively allows for a cover system that provides total access to the tank below. The Double Seal Gutter proves a continuous double seal for irregular or damaged concrete often found in basin retrofit installations. Both of these features are found only on Hallsten Aluminum Covers.
