MAXIDOR RUSTING

I have Maxidor retractable gates on both my sliding doors, I have noticed both my Maxidor gates are rusting and the parts are not stainless steel. Emailed Maxidor - ********** & ********** & ********** Technician from Maxidor came out. Inspection done and the funny thing is he said it might be my pool. LOL I have the gates on the inside. How does the pool rust the gates inside the home? I have called an outside engineer to check and he stated the rust started before the Maxidor gate was put in , like in production. I see a lot of people are having issues with MAXIDOR rusting on hello peter. I wont recommend MAXIDOR because there product rusts. I have it on 2 homes and its very expensive to maintain rust.
