From a metal producer, you can buy 3/8” thick by 12” wide 6061 aluminum in 36 ft lengths. These are delivered to your warehouse at a cost of $1169 each.

You want to sell 4 feet long sheet and you shop worker needs 2mins to cut the rolled sheet into the 4 feet lengths and place then on a pallet for shipment.
