Why Rust Invades Our Garage Doors?

Rust is a natural reaction in the environment. It has several forms and affects iron and all its alloys. Steel garage doors and parts will rust when the material will come in contact with both oxygen and moisture. For this reason, steel is not recommended for high moisture regions. For the same reason, steel undergoes manufacturing processes of galvanization in order to resist erosion. After all, corrosion is basically the destruction of the material by its chemical reaction to specific environments. Who wants to deal with such problems? The good thing is that there are solutions but even then you must take good care of your steel overhead door.

Protect steel from corrosion

All materials have their weaknesses and steel has to deal with corrosion. Rust is rather unavoidable if you consider that this is a chemical reaction of metals to moist environments. All exposed metal parts will eventually rust just by being in the open air and they will rust much sooner if they are exposed to moisture. Steel can be affected by dry oxygen or water. The problem will get worse when steel is exposed to sea salt due to electrochemical reactions. The only metal that is resistant is aluminum. Aluminum has an oxide coating, which acts as rust resistant shield. So, aluminum is resilient to both oxygen and water.

This is the way manufacturers try to cope with steel garage door problems. They actually use aluminum to protect scratches, small seams and holes on steel materials, even galvanized ones. Aluminum is considered a passive material and in physics as well as in engineering this means that it is resistant to air and water. So, when we are talking about stainless steel doors and garage door parts, we basically mean that the material has a passivation layer of chromium which protects it from rusting.

The way steel sectional doors are processed is determined by one's needs. The cheapest way to protect steel is zinc coating. Though, it is important to consider your personal requirements. Do you live by the sea? Does your region have high moisture levels? It's also vital to remember that galvanized materials could still crack and allow entrance to the natural environmental elements, such as moisture and oxygen. If you want to be sure that rust won't knock on your door, remember that lubrication maintenance of parts is always necessary.
