help with angle iron's

[dbreeze225]

hey guys hoping that some one can help i think what i am talking about is called angle irons ( a long bar that has a L shape) allthough not always made with iron could be aluminum or steel ect.. basicy i am working a project and i want to get these angle irons to use around the edges as trim 3/4 in walls (so it goes in 3/4 in in on top edge and 3/4 in down from top edge) all the way around the 4 sides of this project...my problem is i cant find anything good i want it either polished or even anodized ( rather have it polished) but just something that doesnt look rough and streaky like it just cam out of a extruder i got one in homedepot at first not thinkijng about it being polished (wich nothing at home depot is polished ) and went to put it on and it just looked horible being so rough so any chance any one knows where to find this either a web site i can order from ( i did find 2 sites that i could order from with a few "finishing" options but neither one had pics of the diffrent finishing and i want to know what i am buying before i pay for it) or even any stores that cary theese types of products i am new to this type of stuff so any help would be appreciated thanks
