Get to Know What R-Panels and Ag Panels Are

In short, an Ag panel is a term for one of the most popular exposed fastener metal roofing and siding profiles in the construction industry. Post-frame (pole barn) buildings and residential metal roofing are the two largest construction segments for Ag panel use.

There may be some small differences in specifications and details, but the photo below represents the popular Ag panel profile in use today. Distinguishing features of this popular Ag panel are ¾” tall major ribs that are spaced 9” on-center.

A multi-use exposed R-panel fastener metal wall and roof panel was originally designed for use in pre-engineered metal buildings. The use of R-panels has expanded into other areas such as residential metal roofing.

The photo below showcases distinguished characteristics of a R-panel. Major ribs are 1.25” tall and spaced 12” on center.

Look at the photo below. Imagine them side by side on a building. The visual appearance of the panel profile is the difference between the two panel types which is why deciding which one to use comes down to personal preference.

Some contractors prefer the bold appearance of an R-panel (especially in Texas and the Southwest) where bold is considered to be beautiful. Other contractors and homeowners prefer the look of an Ag panel.
