The simplest and earliest style of door is the plank door. Planks of wood or metal are attached side by side to create a flat surface. This simple design and rustic character give the door a sturdy appearance. Grooves in the door can run horizontally or vertically.
Rustic Plank doors are often paired with strap hinges, horizontal batons, clavos, nail heads, or iron window cages.
Modern Plank doors often incorporate oversize hardware, narrow windows, and inlayed metal strips.
