Steel Coating
Structural steel is often painted to protect it from corrosion, but it depends on the situation:
Painting requirements
Structural steel steel must be painted or protected if it's exposed to the exterior.
Best coatings
Some of the best coatings for structural steel include:
- Epoxy: A widely used coating for industrial and marine applications
- Polyurethane: Often used as a topcoat over epoxy primers
- Zinc-rich: A coating that provides galvanic protection and corrodes to form a barrier between the steel and its surroundings. It's recommended for highly corrosive environments.
- PU: A coating that's sprayed on in multiple layers to enhance durability. It's often used for smaller components in machinery or equipment.
Application methods
Paints are typically applied to structural steel by brush, roller, conventional air spray, or airless spray. Airless spraying is the most common method for controlled shop conditions and or field application
Surface preparation
Before applying paint, the surface should be cleaned of loose mill scale, rust, dirt, and other foreign matter.
