TL;DR
A splash plank is the pressure-treated skirt board, typically a 2x8 or wider, run horizontally along the bottom of a post-frame or shed wall at grade, where roof runoff and mud splash hit hardest. It anchors the base of the wall siding, holds the bottom of the metal panels off the soil, and is sacrificial by design, since ground-contact treated lumber there rots decades slower than steel panel edges rust.
