We use a bezzel that is made of .015 thick tin plated carbon steel. Apparently, the plating is done as a sheet and after our stamper forms the bezzel, the edges are no longer coated and the carbon steel is exposed. The problem is that the parts rust in service after some years. In the past we have painted the parts, but that is getting expensive. I am looking for an alternative to painting. This is purely a cosmetic issue, not functional.
FYI, the bezzel is about 4.25 inches in OD and about 3.75 inches ID and the cross section is a "U" shape (picture a flat washer that is stamped parallel to its axis in the middle of the flat forming a U shaped cross section). The bezzel holds the galss into a panel meter that is used in an office environment.
Thanks.
