Sunshine Coast Steel Coating

Steel components need more than just strength — they need the right finish to withstand the elements and maintain their integrity over time. At On The Spot Steel Fabrication on the Sunshine Coast, we apply steel coating solutions to help prevent corrosion, rust, and surface damage.


Our team selects and applies the most suitable coating system based on the conditions your project will face, whether it’s outdoor exposure, industrial use, or structural support. We coat beams, posts, stair stringers, gates, and other fabricated steel items, delivering a finish that lasts. With the right coating, your steelwork performs better and looks great for longer.

Coating for Durability & Performance

We apply protective coatings to steel components to enhance durability and extend product lifespan. Our process begins with proper surface preparation, removing contaminants and ensuring the steel is ready for coating.


Depending on your project requirements, we offer a range of coating options, including industrial painting, powder coating, and galvanising, each chosen for its protective qualities and finish. These coatings form a strong barrier against moisture, chemicals, and environmental wear, reducing the risk of rust and structural damage.


By handling the coating process in-house, we maintain quality control from start to finish, providing consistent results across every component. Whether you’re working on a new fabrication project or maintaining existing steelwork, we help protect your investment with coatings built to perform.

Frequently Asked Questions

  • What types of coatings are used on steel?

    Common steel coatings include powder coating, industrial paints, epoxy coatings, zinc-rich primers, and galvanising. Each option offers different levels of protection depending on environmental conditions and the intended use of the steel. These coatings create a durable barrier against corrosion, moisture, and UV damage, helping preserve both the strength and appearance of steel components.

  • How is steel prepared before coating?

    Before applying steel coatings, the surface is prepared through processes like abrasive blasting, sanding, or chemical cleaning. This removes contaminants, rust, and old coatings, ensuring proper adhesion of the new protective layer. Surface preparation is a critical step that improves the effectiveness and durability of the coating, preventing premature failure and enhancing overall performance.

  • Can steel coating be customised by colour or finish?

    Yes, many steel coating options can be customised by colour, texture, and finish to match project requirements or design preferences. Powder coating and industrial painting offer a wide range of colour choices and surface textures, allowing for both functional protection and aesthetic appeal. Custom finishes provide flexibility for decorative steelwork or branded commercial projects.
