Salt can wreak havoc on outdoor trash cans, especially in coastal regions where salty air and water accelerate corrosion. To design trash cans that withstand salt damage, consider these key strategies:

1. Material Selection: Opt for corrosion-resistant materials like marine-grade stainless steel, powder-coated aluminum, or high-density polyethylene (HDPE). These materials are inherently resistant to rust and degradation.

2. Protective Coatings: Apply specialized coatings such as epoxy or galvanized finishes to create an additional barrier against salt penetration.

3. Drainage Design: Incorporate drainage holes to prevent saltwater accumulation, which can lead to prolonged exposure and faster deterioration.

4. UV-Resistant Additives: Combine salt resistance with UV protection to ensure longevity in sunny, coastal environments.

5. Minimal Metal Components: Reduce exposed metal parts, as they are most vulnerable to salt corrosion. Use plastic or composite fasteners where possible.

By integrating these design principles, outdoor trash cans can remain durable and functional even in harsh, salt-rich environments.
