When you buy a new garage door, you don't want to start replacing its parts in just a few years. The reasonable thing is to keep garage door parts for many years. Most of them should even last for at least fifteen years or even over two decades. Only springs will have to be replaced sooner since they are manufactured to last for a specific amount of cycles. So, parts replacement depends on their initial lifespan expectancy. If this was the case, people would only replace the garage door springs every seven or eight years and keep the other parts for much longer. Though, we notice that we need to make changes more often. How natural is that?
Garage doors might be constructed to last for a long period of time but don't forget that they are affected by external conditions. They are also affected by everyday use and their lifespan additionally depends on the frequency and quality of their maintenance. It will also make a difference whether you have good quality parts and whether their material is suitable for your needs or not. Sea salt for once is really catastrophic to steel parts. If you had a house with an overhead door by the sea and another house with the same exact overhead door inland, you would notice that the door close to the sea will wear much sooner due to erosion. In this case, you would require galvanized parts in order to be sure they will last longer.
Not that galvanized parts are not affected at all by sea salt and high moisture but they are highly resistant. Even if they are affected, it will take a very long period of time till the zinc coat is ruined. Only then, moisture will begin affecting the steel under the galvanized coating. When the right materials are chosen for each area and parts are maintained properly, they last for ages. Don't forget that good lubrication maintenance also protects parts and ensures their long-lasting. So, take good care of all parts and place attention to the springs, since they must be replaced sooner. If parts are meant to last for fifteen years, make them last for twenty.
