What material should above-ground storage tanks be made from?

Above-ground storage tanks are commonly made from steel because of its strength, durability, and resistance to environmental factors. Steel tanks can withstand extreme weather conditions and offer a reliable barrier against leaks and spills, which is vital for preventing environmental contamination. Additionally, steel is readily available and can be easily fabricated into various shapes and sizes to accommodate different storage needs.

While plastic tanks are used in some situations due to their lightweight nature and resistance to corrosion, they typically have limitations concerning temperature resistance and structural integrity under heavy loads compared to steel. Copper and wood are not suitable materials for above-ground storage tanks; copper is expensive and prone to corrosion from certain chemicals, and wood is not a durable option for long-term storage in varying environmental conditions. Hence, steel is the most suitable material for ensuring safety, reliability, and compliance with environmental regulations.
