Been a while since I chipped in on anything (or logged in, for that matter), but I had a bad experience at federal metals turn into a good experience because of russell metals and another place called metalworks. 6 months ago I was looking for some 0.250 thick 3x3 angle iron, 0.125 2x3 rectangle box, and 0.125 1.5x1.5 angle so I could make a t-square fence for my table saw. Federal had decent prices, no minimum that I recall (other than needing at least one a set length, probably 20') but when I asked where I could setup a couple portable sawhorses so I could cut my pieces to fit in my own car, they wouldn't let me. Since I wasn't about to haul some long angle irons out to the road to cut (and risk being run over), I went drove around a bit in the area, and then called Russell Metals.
While the lady was SUPER helpful, she did mention the $200 minimum (or something along those lines, maybe it was $300?), but also said they couldn't do shorter lengths, at least that day. However, as I was about hang up, she told me to check a place in the highfield industrial area (11th and 46th ave, near blackfoot and glenmore) called Metalworks Canada. After driving over there, I got probably the best customer service I've had with the small metal suppliers. I had to wait a week or so for the rectangle box to come in, but the guy said he was trying to get a bit more stock handy for hobby orders. Price was significantly less than metal supermarket (not hard, obviously), but they would cut to any length, and assist with loading. When I came to pick up the order later, the staff drove the stock right to the back of my car on the forklift, and helped me lift the heavy pieces in.
While chatting with the order desk, he said they're trying to get into the smaller order market, and some of their employees used to work at metal supermarket, and didn't like the MO there. Normally they deal with metal gutters and roofing and what not, so they don't show up on a search of metal stock suppliers, but I definitely wanted to toot their horn a bit. They said they could order anything that's readily available, even somewhat strange sizes or alloys, etc.. and they sell by the foot or by the full length, whatever's easiest for you.
That's probably enough from me, hope everyone had a good holiday season!
