Types of Steel Storage Tanks

Flat Bottom Reservoir Tanks.Reservoir tanks come in a broad range of sizes,with the diameter exceeding the height.Reservoirs are economical and effective storage,especially on higher ground.Since these tanks have a lower profile,it is easy to mask them with foliage.Types of Steel Storage TanksFlat Bottom Reservoir Tanks.Reservoir tanks come in a broad range of sizes,with the diameter exceeding the height.Reservoirs are economical and effective storage,especially on higher ground.Since these tanks have a lower profile,it is easy to mask them with foliage.Tanks Specs Drawings - Caldwell TanksComposite Elevated Storage Tank (CET) Multi-Column Elevated Storage Tank (LEG) Pedesphere Elevated Storage Tank (PED) Fluted Column Elevated Storage Tank (FLC) Ground Supported Flat Bottom Storage Tank (FB)
