Yes, powder-coated steel can rust, but it is much more resistant to rust than uncoated steel. Powder coating is a dry finishing process that involves applying a layer of paint in powder form, which is then cured under heat to form a protective layer on the metal surface. This coating provides a barrier that helps protect the steel from moisture and other environmental factors that can cause rust.

However, if the powder coating is damaged or scratched, it can expose the underlying steel to moisture and air, leading to rust formation over time. Additionally, if the coating process was not done properly or if the steel is exposed to extremely harsh conditions, rust can still occur.

To prevent rust on powder-coated steel:

1. **Inspect Regularly**: Check for any damage or chips in the coating and repair them promptly.
2. **Clean Regularly**: Keep the surface clean to avoid buildup of dirt and moisture that can lead to rust.
3. **Use Proper Coating Techniques**: Ensure the powder coating process is done by professionals using high-quality materials.
4. **Apply Touch-Up Paint**: For small scratches or chips, use touch-up paint to cover exposed areas and prevent rust.
