I need to find aluminum channel that is 1.5" x 3" x 1.5" x .25". I need the inside corners to be 90 degrees. I tried purchasing some from an online supplier but when I got them I soon found out it would not work for my application because the inside of the channel was not square. Feel free to email me: whitesideentp@yahoo.com

Believe what you require is called architectural channel, with an inside radius is called structural. Doesn't help you find it but may narrow down the search.

Hello, can the material that you bought be machined to your needs? Can the inside radius be removed? If so any local shop would be able to do this in short order I would think. I do have material on hand to machine what you need, If you would like me to give you a quote let me know.
