Somewhat off topic, since this is both DIY and not electrical [Linked Image]

I am going to be building some hardware (sewing table, computer desks, fabric storage racks, etc) using strut channel. I was wondering if anyone was familiar with the local suppliers in the Portland, Oregon area, and could point me to the 'right place to go' for reasonable prices and a good selection of fitting (especially angle and shelf fittings).

I know that I could, for example, buy all of this stuff from a place like McMaster-Carr (and pay a considerable premium for the convenience), or that I could buy the basic strut and 'Big Orange', for less than half the price of McMaster...but with no assortment of fittings.

I would much rather pay a reasonable premium to a local supplier that has good selection. Can anyone send me a pointer or two?

Thanks
Jon
