Exterior brushed gold aluminum

[Zendavor Signs]

I know this material comes in 4'x8' and 4'x10' .040" thickness sheets, but I need something more rigid than 040. I would prefer to not "laminate" it to a backer, I fear that invites trouble down the road. Dibond comes with this finish, but it is good for interior use only. Any suggestions?

Dibond comes in brushed gold i believe and it's 3mm.

or you can try 080 alum

yeah dibond/alupanel is only warranted for interior though...I dont have a suggestion other than laminating exterior .040 brushed gold to a heavier backer
