The Ultimate Guide to Industrial Tank Coatings

In 2020, the global industrial coatings market reached a value of $83.16 billion.

Industrial tank coating is used to coat fuel tanks, water tanks, etc. due to the properties it provides. As there are various types, it is important to understand the differences, to make sure you choose what is best for you.

What Are Industrial Tank Coatings?

Coatings are used to cover the external surfaces of metal parts, usually to offer some form of protection. In the case of industrial tanks, the main purpose is to prevent corrosion, extending the lifespan of the tank.

Advantages of Coatings

Depending on the type of coating used, a number of benefits are available. Some of the most common advantages are:

  • Increased durability
  • Corrosion protection
  • UV protection
  • Improved appearance
  • Better chemical and water resistance
  • Fire resistance

Different Types of Coating

Several types of coatings are available with different properties. The type you should use depends on the application.

Epoxy Steel

Epoxy coatings are very popular in industrial and marine environments. They adhere to steel very well and provide strong chemical resistance.

They are “surface tolerant”, meaning very little surface preparation is needed, and they can be formulated to cure on damp surfaces, or even underwater if needed.

Polyurethane Steel

It is quite common to coat epoxy primers with a layer of polyurethane over the top. one of the main reasons for this is aesthetics. Polyurethane has very good gloss and color retention.

As industrial tanks are outside, they are constantly exposed to the elements, which degrades the appearance, so a polyurethane coating helps prevent this. They also provide excellent UV protection, another advantage for products that are constantly exposed.


Zinc provides cathodic protection, which helps prevent corrosion. There are two types, Organic and Inorganic. Inorganic is the more popular choice, as it provides superior galvanic protection and excellent heat resistance.

Choosing the Right Tank Coatings

When deciding what type of coating to use, there are several factors you need to take into consideration. You will base these on what you need from your coating.


Ask yourself about the conditions of your project.

  • Is it indoors or outdoors?
  • How long do you need the paint to hold?
  • How much of a concern is sustainability?
  • What standards do you need to comply with?
  • What are the painting conditions?


Think about the way you are working. Would it be better to go with a type that already fits in, or will you need to change things?

  • What types of paints/coatings are you already using?
  • What metals do you need to cover?
  • What equipment do you have?
  • Do you paint before assembly, or assemble then paint?


While the focus should be on what you need, the timeline you are working with could affect your decision.

  • Is drying time a factor?
  • How much can be painted per day?
  • Are you working to a strict deadline?
