This BBS have come up with all sorts of stuff in the past. I have an ugly garden wall that I am wanted to cover with small aluminium cladding painted to a specific RAL colour. However, I want to use small 1 x 1m squares rather than a huge sheet so that I can backlight behind it. However, so far I can find places that do large sheets painted to a specific RAL such as this: https://raaltd.com/aluminium-products/aluminium-sheet-products/pre-painted-aluminium-sheet/ - but they don't appear to offer any cutting. Or I can buy the small squares, but the place doesn't seem to offer any painting: https://www.aluminium-online.co.uk/...t/aluminium-sheet/?filter_sheet-thickness=1mm So, does anyone know somewhere that does both, or if I got the smaller squares, anyone know (or do) spraying to a specifical RAL code? Amaze me BBS ...
Buy the squares from Metal4U at Wetherby then spray them yourself (get some painters pyramids to stand them on).
I've got a book at home which might have the answer in, so leave it with me and I'll have a look when I get home.
Slightly off topic, but have you considered Perspex panels instead? You can get them most colours and cut to size and great for backlighting
