Carbon steel is the most commonly used basic material for waste oil tanks. It has good structural strength and pressure resistance, is relatively economical, and has mature processing technology.

This material can meet most conventional waste oil storage needs, but its corrosion resistance is relatively weak. It requires treatments such as anti-corrosion coatings and cathodic protection to improve corrosion resistance.

Stainless steel is known for its excellent corrosion resistance. It can effectively resist the erosion of waste oils containing acid and alkali components, high humidity environments, or highly corrosive waste oils.

It is not easy to rust and has a smooth surface that is easy to clean. Common types of stainless steel are suitable for storing waste oils with different corrosion levels.

Fiberglass, or glass fiber reinforced plastic, is lightweight, high-strength, and extremely corrosion-resistant. It is non-conductive and non-thermal conductive, and can withstand the erosion of various chemical media.

This material is flexible in molding and can be customized to different shapes and volumes according to needs. It requires no additional anti-corrosion treatment.

Composite materials typically use carbon steel as a base, with an inner anti-corrosion layer such as a plastic layer or rubber layer.

This combines the high strength of the base material with the strong corrosiveness of the inner lining material, balancing both pressure resistance and corrosion resistance.
