TANKS WITH CORRUGATED FLAT ROOF
CORGAL tanks are available with corrugated flat roof systems for those applications that do not desire a pitched roof and where snow loads are not a concern. The corrugated flat roof tank consists of corrugated galvanized steel wall sheets with an interior joist roof system covered with corrugated galvanized steel roof panels. The corrugated flat 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 flat roof tanks are pre-engineered for water containment only. The roof systems are not engineered for any specific sites nor for any live loads. These tanks should not be used in applications with high wind loads nor any snow load.
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 a 24â€ round access opening and cover located on the roof surface.
