Liner panels are interior walls of steel paneling. Similar to exterior walls, they consist of standard 3-foot wide panels (usually 29 gauge) that are screwed to the framing. Full-height liners run from floor to roof and attach at the top to the eave struts on the sidewalls and to the rake rafter on endwalls. Partial-height liners typically attach to the girt at 7'4" and extend an inch or two above it (most steel buildings have a girt at 7'4"). Buildings with liner panels must have a base condition that provides a connection point for the bottom of the panel (see
base options).
