I was looking to buy confectionery rulers - basically a length of aluminum to pour candies or chocolate into and let set - but they are so expensive! I'm considering just buying commercial-grade aluminum bars, about a tenth of the price of the branded confectionery rulers. Does anyone know if there is any risk in using the commercial-grade aluminum, i.e. are the confectionery rulers treated with anything to make them food safe? Any help would be much appreciated!

Do what I did: go to any metal shop and as them to cut you bars of stainless steel , 3/8" x 3/8" by how ever long you want them ( I have 6", 12" and 14" lengths)
Stay away from aluminum, it oxidixes and isn't heavy enough.
You are very right to question the cost of commercial confectionary bars--most of the cost is profit, shipping, packaging, and advertising.
