What is the net coverage of 36 inch wide steel roof deck?

Those of you who are familiar with exposed roofing and siding panels know that architectural panels are typically priced on an overall panel width that is sometimes 2 inches or more larger than the net coverage.
In the structural decking world, we like to keep things simple:  the only width that is published and used to determine the area for pricing is the net cover width.  When we say that Type B roof deck is 36” wide, we mean that you will cover 36” of your roof with each sheet when the side lap is nested as shown below:

As always, please email or call to ASK D-MAC if you have any questions regarding steel deck and accessories!
