Black Stains on GI in SR production


 

Hi!

Good day, I am working in a GI factory, SR and SM. Now I have a question about the GI production. Why the SR production appear the black stain?

Please answer me, thank you.

We all use our own lingo, Wuhui. I think your "GI" stands for galvanized iron, but unfortunately I don't have any idea what "SR" and "SM" stand for, so I don't know what you are talking about. and 'black stain' is a little bit vague. Sorry. More words, please.
