Where can I get this made?

[cropwell]

Anyway, I need to find a U-shaped bit of steel (channel) around 35mm high x 35mm long with the channel width internally about 6.5 +.5/-0 formed from 0.8 - 1mm sheet. Needs to be magnetic, so has to be steel, and finished in a brushed/satin effect.

How many do you need ?
