Want to know the material used to make this turbine

TL;DR Summary

In the attached video, you can see how an archimedes turbine has been built. I just want to know what kind of material is used to build the fins mainly.

After seeing this video, I have decided to make a homemade version of this machine. The axle and other parts can be taken care easily, but I want to know what kind of material is being used to make the blades of this turbine. These part is the most important part while making the turbine.

why not ask the youtuber who posted the video?

One possible material could be aluminum flashing often used at the bottom edge of roofs in the US.

They also have 10" x 10ft rolls that are cheaper. I posted this roll because it was 24" wide.

Polyvinylchloride.

(as stated in a 3 second pop-up at the bottom of the screen @0:37 thru 0:39. There are other pop-ups later in the video.)
