How vertical metal panels become a cut list — full-height columns and the gable rake offcut
Vertical panels run the full wall height, so the count is ⌈wall width ÷ coverage⌉ and each panel is cut to the wall height — to the peak on a gable, then trimmed to the rake. That rake offcut is why gable walls carry a higher waste tier.
What this diagram shows
A front elevation of one 30-foot-wide by 10-foot-tall gable wall with an 8-foot rise, clad in R-panel with 36-inch (3-foot) net coverage. The wall is divided into ten vertical panel columns, each running the full height; one column is highlighted in blue and labeled "1 panel = 1 column, cut to the peak." The panels are ordered to the peak height of 18 feet, and the two triangular areas above the eave line, outside the gable triangle, are hatched red and labeled "rake-trim offcut (waste)." The takeaway reads: ceiling of 30 divided by 3 equals 10 panels, each 18 feet, cut to the peak and trimmed to the rake.
