Another example of a rigid electrical conduit is emt electrical metal tubing which is most commonly made of galvanized steel but can also be aluminum.
Popularly known as thinwall.
The one weakness emt has the one that may make nonmetallic a better choice is corrosion.
While emt is bent with a hand bender or a knee for a slight bend in a hot attic rmc properly installed could be used a chin up bar.
