Single Wall Tanks

Southern Tank manufactures reliable single wall steel tanks for aboveground storage of a wide range of fuels, oils, chemicals, and other liquids. Single wall tanks offer a cost-effective solution when secondary containment is already in place or not required by code.

Available in a variety of sizes, orientations, and support configurations, Southern Tank’s single wall tanks are trusted by industries across the country for their rugged construction, versatility, and long service life. Carbon steel or 300 series stainless steel materials are available.

Where Single Wall Tanks Are Used

Single wall tanks are ideal for:

• Facilities with concrete containment basins or dikes already in place
• Fuel and lubricant storage at maintenance shops, industrial plants and agricultural facilities
• Waste oil and used fluid collection sites
• Water treatment and chemical storage systems
• Remote sites or operations with portable containment pans
• Backup generator fuel storage where SPCC compliance is otherwise met

Southern Tank’s single wall tanks are a go-to choice for customers who need dependable storage and already meet local, state, or EPA secondary containment regulations through other means or are not regulated by local codes.
