Protective coating or scale? on cold roll sheet
Protective coating or scale? on cold roll sheet
(OP)
I am trying to put a bright finish,without without heavy grind marks, on 14ga. cold roll steel.
I have had good results with material that has been left out and has some mild rust. The new sheet I have purchased has a blackish blue coating that is very difficult to grind through and still leave a smooth finish. Is there a way to cut that layer without grinding?
Thank You
