Before commencing a painting job on a steel tube, the necessary type of paint must be identified. This factor largely depends on the existing condition of the structure – oil-based is usually required if the steel tube is new, while a latex-based paint would be more suitable for previously-used surfaces.
To start the process, scrub the steel tube free from any grease residue with a wire brush and degreaser. In case the steel tube is heavily soiled, then a power washer would be helpful in eliminating any dirt and grime.
The next step after ensuring the steel tube is spotless is to cover it with a primer. After that, you can go ahead with painting, either utilizing a brush or roller for the task. Remember to start from the highest point of the tube and continue down.
Applying a coat of paint to a large steel tube may require one to reach higher than usual; for this purpose, it is best to deploy a ladder with utmost caution.
When the brushstrokes have dried to perfection, you can bring the steel tube into play.
