MAXIDOR SLIDING GATES

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. 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.
