Foster,
I can't offer much on the extruded Al front; this is fairly specialised and I've not looked into it for the Swift, preferring to use timber surrounds.
Capral is a good option, but there are many ornamental Al suppliers for the building industry, so perhaps a visit to a building material supplier (and perhaps more likely, a kitchen supplier) might be a good idea.
Good luck, and please keep us posted!
Cheers,
Hugh
