Reviewing The Steel Perimeter Prep Band Before Surface Preparation

At the steel perimeter prep band, related roof surface preparation guide surface preparation should use the outer steel edge as one reference and a second line farther inside the panel as the stop reference. Number each perimeter segment before work begins, keep corner hardware and drainage outside the band, and leave one steel segment untouched.

Address one numbered segment at a time with small sections, ending each pass before the next corner or material transition. Recheck if the finish changes. Record a location number and a inside-line mark so the next visit can continue from the correct perimeter section.
