The sheet will have laser cut parts, so if will not lay flat under its own weight then its a no go. I found a local supplier, but they are kinda hard to deal with, so I wanted a backup. I'll ask the shop if they have a way to deal with a little bow.It will flatten mostly fine, but it does take a slight roll. It won't be enough to prevent working the material and using it in the structure or as a skin. But if you're trying to just have a dead flat, straight, and true sheet to lay on a table, you won't get that. Also, I've tended to get a bit of kink a few inches from one end which, hasn't affected any parts I've ended up making, but it has affected where I cut those parts from the sheet.
If you are just making ribs or smaller skin pieces I'd have no issue using the rolled sheets. If you're gonna make a big wing skin or something and are using basically the whole length, it's iffy. If you had one bad corner, would it kill your part, or are you cutting a big corner off anyway?
Of course I'd never want to pay the freight charge for just a few sheets so after we ran out of our main order of metal we went to rolled. If you'll use it, definitely try and see about ordering a bunch of sheets at once to spread that freight cost out.
If they don't handle Al then I won't bother. Aluminum is basically a commodity. No one is varying significantly on price. I have 10 quotes and all are right at $160 +/- $10 for 48x96. The kicker is how close they are/shipping.Spruce now has an outlet in Harrisburg....they do not handle aluminum but maybe you could talk to them as to if you could pick it up there as a special?
