I go to a few diffrent places, just depends . lowes metal rack ,expensive but convenient , weldin shop next town over, race car fab shop, but my fav is the scrap yard ,they may or may not have what you want but at .25 cents a lbs its the cheapest buy far.
we have 2 metal supply shops 2 towns over.. 1 is a 25m drive, the other is 35m.. have a scrap metal / surplus shop that is about 35m away as well.. but burried in the middle of an old industrial district.. so takes a bit to navigate too.
the salvage shop has better metal prices by far.. but is the hardest to get to. the closest metal shop gouges you a bit in that if you puy a non standard size, they charge you for the entire piece, plus a price per cut.
thus if you buy, say.. a 4x5 sheet of 1/8.. that starts life as a 4x6 sheet at their shop. you pay the 4x6 cost, plus a cut cost. if you got a 3x5.. you'd pay 2 cut costs. IE.. pay more.. get less.
last time I re skinned a section of loader bucket I ran into that.. I asked if I could have the cut pieces since I paid for them.. NOPE! last time I've dealt with them after that robery.
should have said I wanted the 4x6 piece AND 2 cuts.. theoretically wouldn't have cost any more and would have had 2 leftovers to play with..
that's why lowes metal rack sometiems gets my business, if I just need a piece of cold rolled or a quick piece of angle to finish up a job... pay more.. but is 5m away and convienient.
that one metal shop I mentioned that gouges. you can't get same day service, even on in stock metal. you walk in, pay, fill out a cutting ticket, then are given a time the next day it will be ready.. even if you ar ethe only customer and all the shop guys are standing around the door smoking
the salvage people will walk right out with 'salvage sized' blow torch with a 100' lead and light it off their cigar and cut stuff as you point at it. measur eit up and load it for you while you pay.
I TRY to use them when I can..
