Industrial plants & facilities are often faced with the challenge of finding a protective coating system to protect their assets. What are your best options when selecting steel coatings? Whether it’s for corrosion protection, chemical protection, or even just for aesthetic reasons, it may be difficult to determine which type of industrial coating is needed to protect infrastructure. Industrial coatings help protect steel from deterioration caused by humidity, salts, and pollutants. There’s a wide range of industrial coatings that can be used to protect your asset from corrosion so let’s look a few different types:

Epoxy coatings are one of the most widely used steel coatings in industrial and marine markets. Epoxies are known for having excellent adhesion to steel and provide good chemical resistance. They are also often sold as “surface tolerant”, which means they will adhere well to surfaces with minimal surface preparation. Epoxies can be formulated to cure underwater or on damp surfaces which make them unique for certain applications. Epoxies are generally categorized as water based, solvent based, or solvent free (100% Solids Epoxies).

Polyurethane coatings are often used as topcoats over epoxy primers on structural steel. The main reason these coatings are specified is because they have excellent gloss and color retention, as well as outstanding UV resistance. Polyurethanes are mostly used in exterior applications, although they are sometimes used interior for aesthetic reasons. Polyurethanes can also be formulated as a direct-to-metal (DTM). There are two major types of polyurethanes: Aromatic and Aliphatic. Aliphatic polyurethanes are more resistant to UV attack and typically just used in exterior applications. Aromatic polyurethanes are extremely tough and provide excellent abrasion resistance, but they do not have good color stability and will change color when exposed to UV light.

Zinc coatings contain a high percentage of zinc dust and protect steel from corroding by providing cathodic protection. The type of zinc rich coating is defined by the binder that’s used during the manufacturing process. The two types are: Inorganic Zinc (ethyl silicate) and Organic Zinc (epoxy, polyurethane). Inorganic zinc is one of the most popular steel primers in the industrial world. Inorganic zincs are known for their high heat resistance and generally provide better galvanic protection than organic zinc. Inorganic zinc is normally spray applied at 2-3 mils DFT and no more than 5 mils DFT to avoid mud cracking. Organic zinc can usually be applied by brush, roll, or spray and can be applied over a SSPC-SP-6 Commercial Blast, while an Inorganic zinc needs to be applied over a SSPC-SP-10 Near White Blast.

These 3 types of coatings are some of the most common that you will see in industrial markets such as: Chemical Processing, Pulp and Paper, Food & Beverage Processing, Power Generation. Mining, Petrochem, and Marine. There are several other coatings that are used in these markets such as Alkyds, Polyaspartics, Polyureas, Polysiloxanes, Vinyl Esters, to name a few.
Now that we’ve discussed some of the key coatings used, let’s take a look at the two different types of coatings systems used, which are single coat and multiple coat. Single coat systems require the applicator applies the coating very carefully because there’s a higher chance of holidays and other defects. In most cases, a multiple coat system is used in industrial and marine environments. Often times the coating system starts with either an epoxy or zinc rich coating as the primer, an intermediate coat of epoxy, and a finish coat of epoxy or polyurethane. One of the main reasons multiple coat systems are used is because certain materials do an excellent in one aspect of corrosion protection but not so well in others. In less aggressive areas such as an industrial maintenance project in a low humidity area, it’s common to see a 2 coat system applied. In more aggressive areas such as a chemical plant in a high humidity environment, it’s common to see a 3-coat system.

The trend of using corrugated steel floors when building pre-fabricated houses is preferred by many customers thanks to its high durability and fast construction time. Refer to the article below to find out information about the common types of floor in industrial houses, as well as why deck mezzanine corrugated steel floor is the optimal choice when constructing pre-fabricated steel buildings.
1.Common floor types for pre-fabricated steel buildings
1.1 Concrete Floor
KAIYAO are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
Concrete floors are chosen by many customers when building pre-fabricated steel buildings because of many outstanding advantages. Besides good bearing capacity, concrete floors also have high durability and good fire resistance.
1.2 Cemboard Cement Sheet Floor
Cemboard cement floor has the greatest advantage of being compact, easy to install, fast construction so it is often used in mezzanine flooring works, advanced renovation, especially the construction of civil pre-fabricated houses.
Thanks to the close attachment of ultrafine components such as silica, cellulose fibers and Portland cement, cemboard cement sheet floors have a certain hardness and good bearing. However, the horizontal bearing capacity of the cemboard plate is quite underestimated and the flexibility is not high. In addition, the cost of the product also has a greater difference than the same material lines. Therefore, the applicability of cemboard cement sheet floors in pre-fabricated steel houses is still very low.
1.3 Pre-fabricated Lightweight Concrete Panel Floor
Pre-fabricated lightweight concrete panels are also selected by many customers in construction, especially with civil works. Thanks to its lightweight, the product is suitable for installation in upgraded buildings that cannot be changed much in foundation structures or those with weak ground.
1.4 Deck floor
Deck floor is a combination of armored concrete and corrugated steel deck floor, which is often applied in mezzanine floor and standard floor in pre-fabricated steel buildings. The main component of the corrugated steel floor deck is galvanized steel to help the product have high durability, good corrosion resistance. In addition, galvanized steel also possesses a shiny, beautiful appearance, contributing to increasing the aesthetics of the building. In terms of structure, the floor corrugated iron waves are large so there is high bearing capacity.
Corrugated steel floor deck is very popular in the construction of pre-fabricated steel floor (Source: Pebsteel)The installation of a corrugated steel floor deck does not require many complicated stages. The investor can construct multiple deck floors at the same time without using the formwork like traditional concrete casting floor. As a result, the floor construction time is shortened while saving the amount of concrete used, helping investors optimize construction costs. Currently, deck floor is commonly applied in pre-fabricated steel frame works such as showrooms, office buildings, factories, warehouses …
