How to Paint on Structural Steel Sections

Structural steel is a versatile and durable material heavily used in the construction industry to build a wide variety of projects. Whether it be buildings, bridges, towers, railways, or tunnels, steel can be shaped and mended into different parts to accommodate these projects with ease. Compared to materials like wood and stone, steel does not wear down easily, and is more affordable, making it a more reliable building material overall.

Being a very versatile material, structural steel offers a good number of advantages, and one of them is that you are able to paint on steel sections using structural steel paint and provide color and a layer of protective coating.

How do you paint on structural steel?

Structural steel is designed to be durable, providing a sturdy foundation in which a structure can be built on. Adding paint to these steel sections helps improve the design of the structure while improving the strength and lifespan of steel. While painting on steel might seem like a straightforward task, there are a number of processes that you must accomplish before applying the right amount of coating. Here is how you can paint on structural steel.

Clean the steel sections

Clean The Steel Sections

Before you begin to apply the primer and final coat on your structural steel, the first thing that you need to do is to clean the steel sections. Dirt, dust, debris, liquids, and other substances can cause damage to the steel surface, which can compromise different sections of painted steel if not cleaned properly. Using cleaning solutions like soap and degreasers would be able to remove any substance present on steel. For the best effect, using hand tools can help make the process more efficient, and ensure that the surface would be kept dry after cleaning.

It is best to thoroughly clean all parts of the steel section that will be painted to prevent any substances affecting the primer and paint during the process. Once it has been cleaned, the next step is to apply the primer to begin the painting process.

Coat the primer

After cleaning the steel sections, you can now apply the primer, which helps provide an extra protective layer that helps the structural steel paint stick properly to the surface. Similar to painting on other surfaces in a structure, the primer is important to ensure the material being painted would still retain the same durability. Using a galvanized primer is very effective, as it allows most kinds of paint to attach on the surface, and strengthen the steel section as well. Apply the primer using a brush specialized for latex and epoxy paint, which would spread the primer on the surface evenly. After applying the primer, let it rest for a number of hours to let it dry up.

Prepare the paint

Prepare The Paint

While the primer cures, you now have the time to mix the paint that you would use on your steel sections. Mixing the paint with the proper formula would prevent it from getting easily damaged due to wear and tear, and provide the right shade of color that matches the whole structure. Make sure the paint is properly mixed before you begin applying it on steel.

Apply the paint on steel

Once the paint has been properly mixed, the structural steel can now be painted on. For the best effect, using epoxy paint allows you to cover up and add color to your steel sections accordingly. When it comes to painting, it is important to follow the design aesthetic of the structure itself for the ideal symmetry. For industrial sections and machinery, it is important to use the addition of color to signal personnel about hazards and locations that will allow them to operate. Like the primer, let the paint dry for a number of hours to see the final product.

Key Takeaway

Steel is one of the most versatile building materials around, as it can be used for almost any type of structure. Painting on steel not only provides an added shade of color, but it also creates a protective layer that provides more strength to the steel, allowing it to withstand daily wear and tear much better.
