Making steel coils from an idea in MR

[doctorwayne]

"Reading", as the old Public Service Campaign used to say, "is fundamental!" It occurred to me to read the article a little more closely!
The author says that hot rolls cool to that dark blue gray color and then start collecting a patina of rust. I'm guessing the shiny silver rolls are stainless.
Makes sense to me!

Unless the mill is one dealing with stainless steel (generally considered a "specialty" steel), chances are that the shiny ones are tinplate. Coils were also shipped in boxcars, on heavy-duty wooden skids. I'm not sure why, but at the plant where I worked, most of the cars were U.P. 50' or 60' cars, with double plug doors. I didn't work in this department, but the coils were likely either tinplate or a type of galvanised steel, and, being shipped on skids, were shipped "on-end".
