Finish Options

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 (standard): the top of the curb has a smooth finish created by saw cutting.
  
  
• Split face (standard): the face of the curb has a rough finish created by being split.
  
  
• Thermal top: the top of the curb has a finish created by being sawn, 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 roughen the surface to give it a sandpaper-like surface.
  
  
• Thermal face: the face of the curb has a finish created by being split or sawn, then braised with a blow torch.
  
  
• Clean back: protrusions greater than 1/4-inch are removed using hand tools to create a smoother surface and stay within tolerance.
