Common Problems of Metal Sheet & Coil: Steel Substrate Defects

From the time metal coil is formed and coated in a steel mill, to when it is slit in a metal roof manufacturer’s facility, there is a small possibility for certain defects to be present. On today’s Q&A Mondays episode, Thad Barnette, Adam Mazzella, and Jeff Hock explain what types of defects can happen and how steel mills, paint lines, and metal roofing manufacturers work to ensure those defects don’t reach end users. They also discuss how to spot certain defects that may slip through, and what you should do as a metal fabricator if you notice problems.
