If anybody has worked in the past with some Chinese manufacturer that can provide Aluminium extrusions like this, please share the name/website. I want the side extrusion as shown in the linked picture direct off-shelf and do not want to bear the price of a custom die build. So far, I only found an American supplier who I know is not an original manufacturer.

If anyone knows a manufacturer, I'll really appreciate the help.
