What are common materials used to construct USTs?

The most common materials used to construct underground storage tanks (USTs) are steel, fiberglass, and various composite materials. Steel is widely favored for its strength and durability, making it suitable for storing a variety of liquids. However, steel tanks are often susceptible to corrosion, which has led to the development of fiberglass tanks. Fiberglass tanks are resistant to corrosion, lighter in weight, and easier to install, making them increasingly popular. Composite materials can also provide a blend of advantages, combining strength with resistance to environmental factors.

The effectiveness of these materials in preventing leaks and contamination makes them essential for compliance with environmental regulations and safety standards in the management of hazardous substances.
