How Coastal Air Contributes to Corrosion
Coastal air has certain components like salt, water, and humidity which support high rusting rates. The salt particles in the air, when they land on your metal garage door, can cause some small abrasions to form. This moisture gets into the rust due to various cuts. This rust can make the metal weaker with time and cause damage to the door as well as stains that are not a good look.
01
Salt
Salt carried by the sea breeze deposits on metal surfaces and erodes protective coatings.
02
Humidity
The high humidity by the coast accelerates rusting, especially with salt present.
03
Temperature Fluctuations
Coastal environments have drastic changes in temperature, causing the metal to cool and warm, increasing moisture and rust formation.

Noticing Rust and Corrosion Early to Prevent Garage Door Damage: The sooner you catch it, the more preventative actions you can take before it becomes a bigger problem.
