Gold plated sheet cladding
I am a civil engineer working for a construction company,at the moment we are building a large mosque in Jordan.This mosque has a 15.6m diameter dome which The Owner want it to be externally cladded with gold plated sheets (base metal is not specified yet). I would like to know the technical information and specification on this subject.Jamal Alawi

Hello Mr. Alawi. Gold plating is an interesting construction because it does not tarnish, but remains bright. It is possible to gold plate the sheet before fabrication, or after fabrication but before erection, or in situ after erection.
Preplating probably isn't a good idea because of possible damage during fabrication, and newly trimmed surfaces being unplated. Plating after fabrication and before erection is probably best if the size of the parts permits (you'll certainly not find a gold plating tank large enough to accommodate a 15.6 m diameter dome).
Control of color may become an issue, so have everything plated together by one source.
You'll probably want the substrate nickel plated first, then gold plated.
