Thanks for contacting us with this problem. I believe this is some sort of electrolysis, as your contractors suggests. While your salt water pool is a suspect, I don't think it's ultimately the culprit. I believe this can happen simply from having the aluminum track lay on top of concrete. There are actually chemicals in the concrete that can cause this kind of corrosion. It would be best if you could place some type of plastic or foam barrier between the bottom of the track and the concrete.

Hello there. We carry one type of patio door track, our 80-106. Review the video below and see if you think you could adapt this track to your door. Let me know if you have further questions. |
