Re: Cold rolled steel, flats or square for use as rails.

who cares. when you have it ground, the lasagna noodle shape will be
a much larger concern than the rust.

cold rolled is a set unit. when you change any part of it, the
internal pressures effect change on other parts.

much better to start with hot rolled, stress relive it, then grind it.
