How about a link? (Lowes) Or Home Depot. Its called "5V" for the profile. I like the broad flat surfaces of it for my screw penetrations. If you look at a section "on edge", you can count five "V"s - a double, a flat section, a single, a flat section, a double.
Its also called "U over V" assembly, because there is just a little more space between the double V on one side of the panel, compared to the other. The wider is the "U", and the panels get overlaid so that goes on top of the narrower one - again, flat surface for your screw, while the double Vs help ensure water can't be blown sideways between them.
Thank you.
