Bullnose ceramic tile trim

Bullnose is a term used in building construction for rounded convex trim, particularly in ceramic tile.

Uses

Bullnose trim is used to provide a smooth, rounded edge for countertops, building corners, Verandahs or other construction.

When referring to bullnose, it is sometimes modified by adding the word quarter or half. In the illustration, one piece of quarter-bullnose tile is juxtaposed with a plain piece of tile, to create a finished look - note that the top trim strip shows a quarter-bullnose on two of its sides.

However, when referring to counter tops (such as a granite counter top in a kitchen) which extends beyond the edge of the underlying cabinetry, either a quarter-bullnose or half-bullnose edge may be used. A half-bullnose can be constructed by bonding two sections with quarter-bullnose, effectively creating a 180-degree curve, in order to create a more finished appearance. This would effectively double the thickness of that portion which extends beyond the cabinetry.

Bullnose is used in highway construction in North America to buffer and protect the end of the Crash barrier or Jersey Barrier at an entrance and exit ramps.
