Yeah, I've also searched a long time to find them. It always takes a few days until they ship the profiles because they make them exactly like you want them. But normally you'll get them within 2 weeks, sometimes earlier. Prices are also okay as long as you don't use anodised 2mm alli! I've used it one time but you see every little fingerprint, RAL colors are much better, cheaper and always look the same. Much easier to keep them clean...
Its a german online shop and they have a config tool you simply write the numbers in you want. They offer 1, 1,5, 2 and 3mm natural, anodized(eloxiert) or RAL colour coared alu sheets bent to what ever form you want. They also have steel, copper and other materials in the list.
Thats the U-profile configurator below. But try it with different thickness, 2mm is sometimes cheaper like 1,5mm thickness for some unknown reason. For relatively small housings 1mm is enough.
I like the white or anthracit RAL coatings. Looks pretty nice and is durable like paint. They should ship within the EU zone it only leads to slightly higher shipping costs.
You need to chose material and thickness first from the dropdown menus(upper right side) then enter A, B and C numbers below, then length and then chose which side you want to look at/ be color coated (for instance outside or inside).
It calculates on the fly and the price is shown in the lower left side below the picture of your profile.
Its actually pretty easy..

That's the driver case of my last fixture.
