I helped a friend fix his sagging garage doors.
They need a cable and turnbuckle because the door frames are not rigid enough to handle the weight without sagging.

Parts used for tooling often require a black oxide finish.
After these parts were tig welded, they were bead blasted, and then coated with black oxide.
That begins with a boiling degreaser, then rinse water, then black oxide coating, then rinse again, and then a penetrating oil followed by an oven bake.
