Having owned and ran many roll forming machines in the past, I know from experience that no one would ever subject their costly and precision forming machines to rusty materials. I didn't even like to run new hot rolled materials through them without having a series of brushing and cleaning rollers cassette in front of the forming rolls
Mill scale and rust gets embedded in the hardened rolls over time or just accumulates on their surfaces causing unfavorable results which will lead to the product being rejected by the clients

THis was probably only for show as to what can be done. Even in China people are not so stupid as to ruin their machines for future work.
