Use Trim Coil LF calculated when you bend trim from flat stock and want the order to account for blank widths, trim coil width, roof edge runs, Valley J, Z-closure, and trim waste instead of simply copying raw edge lengths.
When To Use This Source
Use this source for trim coil lines where the amount you buy depends on how many trim blanks fit across the coil. This helps the order reflect the trim pieces you actually fabricate.
- Raw eave, rake, ridge, hip, valley, headwall, and transition LF tell you how long the roof edges are, not how much flat coil those profiles need.
- Blank widths tell the app how wide each trim profile is before bending.
- Trim Coil Width tells the app how many blanks fit across the coil width.
- Valley J-strip and Z-closure can add coil material from the roof lines they follow.
- Trim Waste is added after the calculated trim coil amount.
Example
If your ridge cap uses a 12 inch blank and your trim coil is 24 inches wide, two ridge cap blanks fit across the coil. A 100 LF ridge run would need about 50 LF of coil for that ridge cap before trim waste is added. If the blank width is wider, fewer pieces fit across the coil and the coil LF increases.
Where To Change It
Open Material Config in Instant Report and review Trim Coil Width, Trim Waste, and the Trim Widths table. In the Order Template editor, choose Trim Coil LF calculated for material lines that should use this trim coil estimate.
