half round

Semicircle molding shape

Half round describes a shape that is semicircular in cross-section—flat on one side, curved on the other.

The term appears most often in construction and metalworking: a half round file for smoothing concave surfaces, half round molding for decorative trim, half round gutters with their characteristic curved profile.

We need half round stock for the railing.
