Last time, Brighton, MI, metal door and corrosion experts at Door Innovation discussed how deicing salt could be the culprit behind your corroded metal door frame. Salt is the issue again this week when Door Innovation exposes the relationship between coastal environments and propagation of corrosion. Here’s how you can work against these conditions to keep your door in working order.
Question: Do Coastal Environments Accelerate Corrosion Propagation?
Last week’s article outlined how deicing salt can mix with water, ultimately leading to corrosion. Filled with spraying saltwater, coastal environments face similar corrosion risks. A nearby ocean poses a much greater corrosion risk than deicing salt, and not just because of the amount of water involved.
Answer: Yes, for 3 Reasons
Corrosion is the result of contact between an electrolyte — a liquid-salt solution that carries electrical ions — and a metal surface. Electrolytes are formed when salt dissolves in water. The sea is a huge body of electrolytes, and when its waves crash onto the beach, tiny electrolyte particles can spray thousands of feet. Seawater can make contact with business’ metal doors from a surprising distance.
When seawater evaporates, the salt doesn’t get absorbed into the air. H2O tends to evaporate into relatively pure water vapor. Sea spray causes something similar to happen, however. Waves crash into thousands of tiny seawater droplets. If these evaporate in midair, leftover salt particles may aerosolize: that is, be carried on the air. As a result, salt crystals flying in the wind can travel long distances — possibly straight to your metal door.
Dew is the third reason you’ll find many corroded metal door frames in coastal environments. As temperatures drop overnight, water vapor tends to descend and condensate. That’s why grass is often wet in the morning. The more water vapor there is, the more dew you’ll end up with: that means coastal areas are likely to get far more of it. Water vapor can seep into the tiniest of your door’s nooks and crannies, corroding the frame from the inside when it reverts to liquid.
Let’s say you’re already noticing a corroded metal door frame. Act quickly to prevent the corrosion from spreading too deeply into the frame or, worse, the surrounding area in the building’s foundation. Cut out the corroded portions of your door frame and replace them with a Jamb Patch from Door Innovation. This corrosion-proof galvannealed layered steel restores the function of your door for years to come. Call Door Innovation today at (810) 227-7111 or visit their website to get yours. Tune in next week, when Door Innovation will be discussing how floods and hurricanes can aggravate metal door frame corrosion.
