Finish Descriptions

There are a variety basic finish options available which may be applied to the top and face of a vertical curb. Any combination of these finish treatments may be specified, i.e., sawn top, split face; thermal top, split face, etc.

  • Sawn top: the top of the curb has a smooth finish created by saw cutting.
  • Split top: the top of the curb has a rough finish created by being split.
  • Thermal top: the top of the curb has a finish created by being split, then braised with a blow torch to roughen the surface to give it a safer, sandpaper-like surface.
  • Sawn face: the face of the curb has a smooth finish created by saw cutting. Not available on radius curves. Note that sawn faces can also be thermaled with a blow torch to create a smoother face front and/or back.
  • Split face: the face of the curb has a rough finish created by being split.
  • Thermal face: the face of the curb has a finish created by being split, then braised with a blow torch to smooth the surface.
  • Clean back: protrusions greater than 1/4-inch are removed using hand tools to create a smoother surface and stay within tolerance. This is the standard back finish for bridge curbing.
  • Sawn back: provides the ultimate clean back; available on vertical straight curb only.
  • Rock Face: hand chiseled to add roughness, a distressed finish. For landscaping use only.
