- (For metal bars or other materials in bar form, see bar)
Bars are a grill or lattice of strong poles that prevent the passage of everything but liquids and light. A portcullis or classic barred prison door is a good example. No creature or object can pass through bars*, although in a future version this behaviour may be altered slightly (see below). Bars can be used vertically as walls or on a flat surface as floor grates.
Bars can be used to block off channels intended for the passage of water, or magma if they are built from magma-safe materials, whether to keep dwarves from falling in or to keep bad creatures from invading along them. They share much in common with fortifications, which can also be used for the same purpose. Bars can also be fired through like fortifications by marksdwarves and enemies alike, and provide no protection for either (unlike fortifications).
Bars can be built via the menu by a dwarf with the furniture hauling labor. They can be constructed as either "Vertical Bars" ( ) or horizontal "Floor Bars" ( + ). Floor bars are intended to be built over Open Space, though it is possible to build them directly on top of an existing floor (to increase room value, for instance). Both Floor Bars and Vertical Bars are built with one metal bar by any dwarf with the Furniture Hauling labor enabled.
Bars are identical in function to grates but distinctions will be made in the future. More specifically, bars may allow for the free passage of verminous creatures while blocking the passage of larger creatures. Bars may even allow small or narrow creatures (such as cats) to pass through. Grates will likely prevent the passage of any but the smallest vermin. Bars may also allow items to fall through, whereas grates would not.
(* Note - there is a known bug that allows flowing liquids to, occasionally, "push" creatures through bars and grates, though they still work as intended with non-flowing liquids.)
