TANKS WITH STANDARD ROOF

The most common CORGAL tanks in use are the tanks with 30-degree roofs. This standard tank consists of corrugated galvanized steel wall sheets with a 30-degree galvanized steel roof system. The standard 30-degree roof tanks are equipped with a geotextile preliner and either a 25 mil. or 40 mil. flexible membrane main liner for water containment.

The corrugated high-rib roof (CHR) design is standard on all models 12′ diameter and larger. The 6′, 8′, and 9′ diameter models have a flat-seam (FS) roof as standard but the corrugated high-rib roof is available as an option.

The 30-degree roof tanks are pre-engineered for water storage in a seismic zone 2B with a 90 MPH wind speed at a UBC Exposure C location. Roof snow load ratings are available for specific locations.

TANK ACCESS

All tanks having 2 rings (models XX02) or taller have a removable side access panel that is used for interior tank access during construction or for emergency access.

All tanks have an access opening and cover located at the peak of the roof. The opening is 22″ round for tanks from 6′ through 24′ diameter. The opening is 36″ round for tanks 27′ diameter and larger.

Tanks 12′ diameter and larger also have a manhole access and cover located on the lower end of one roof panel for side roof access. The manhole opening is trapezoidal 24″ X 16″ X 19″. The cover has a latch with provision for use of a padlock for tank security.

An 18″ round access hatch and cover is available as an option for side roof access into 6′ diameter flat-seam tanks. A 24″ round access and cover is available as an option for side roof access into 8′ and 9′ diameter flat-seam tanks.
