Mfgr. asks if ground current causes corrosion of aluminum garage doors

We have an Aluminum garage sliding screen door unit, which is installed in the Garage door opening section with a header a track and side jambs, and the door panels will be lifted into the installed tracks and slide across the opening along the 3 to 4 panel track. Now my question is we have homeowners call a few months after about a bubbling looking coating of sometimes powdery substance appear on their sliding door panels. We were told this may be a form of Oxidation. Formed by an electrical current running underground, that affects the aluminum. And is the remedy to connect a ground wire to the side of the main frame to a grounding rod in the ground?

Corrosion of bare aluminum is to be expected if frequently wet. Most patio type sliding aluminum door frames are anodized, which prevents the problem.
