Stone, quartz, porcelain, wood, laminate, and solid surface have different span limitations. A narrow overhang on a continuous cabinet run may need less support than a deep seating area. Cooktop and sink cutouts reduce strength and can change support needs. The fabricator should specify brackets, corbels, steel plates, or hidden supports before cabinets are installed.

Key considerations

  • structural stability
  • crack resistance
  • load support
  • hidden supports
  • corbels
  • steel brackets
