Metal siding profiles — exposed vs concealed fastener

The defining difference between metal siding profiles is where the fastener lives: an exposed-fastener rib is screwed through the crown (visible), while snap-lock/standing-seam and board-and-batten profiles hide the fastener behind the seam or batten cap.

What this diagram shows

Three end-section cutaways of metal siding profiles on a substrate. Left: an exposed-fastener rib panel with a screw and rubber washer driven through the top of a rib crown, visible on the surface. Center: a concealed snap-lock / standing-seam panel where a clip is hidden inside the raised seam and fastened to the substrate. Right: metal board-and-batten where raised batten caps snap over the panel and hide the fastener.
