Standard Curb Styles
There are two standard curb styles: vertical-faced and sloped-faced.
Vertical curbing features a sawn top and a split vertical face that makes it ideal for use where traffic speeds are restricted, such as city streets, congested areas, traffic or safety islands, ramps on grade elimination and cloverleafs. Furthermore vertical curbing is used in cities and towns because its nearly 90°-edge makes it less of a tripping hazard for pedestrians.
Sloped curbing is installed at an angel with the top of the rectangular block covered by dirt, grass or pavement. This style of curbing is primarily used in parking lots, private road and suburban roadways.
