Aluminum and Steel Corrosion 1

[RDM]

Does anyone have any general information on ways separating aluminum steel when connecting them together? I am working on a remodel and the architect would like to use polished aluminum frames and they would have to be supported by existing steel framing.

Are there any special coatings, plastic washers, etc. that someone is aware of. Any help is appreciated. Thanks.

I have been reading on this and it seems like something is going to corrode regardless. Stainless steel appears to corrode aluminum as well. I have to do aluminum handrails all the time that connect to steel. Each manufacturer has their own specs on the paint to be used or tape req'd to separate dissimilar metal contact.
RDM, you may want to check out the mfr's specs on the frames you are using and refer to them in your dwgs., in additon to whatever other precautions you decide to use.
