In Pole Buildings, Wainscoting is Used on the Exterior

It uses an alternate siding panel to cover the lower approximately three feet of the exterior walls. The most common application, with steel sided buildings, is to use a different color steel panel on the lower wall than the upper, this makes it more aesthetically pleasing.

A nice function of wainscoting on your pole building is that it allows the ability to quickly and easily change out a short steel panel in the event it becomes damaged.
