Standard Specifications
In accordance with the industry standard *GB/T 23453-2009: Natural Granite Building Slabs*, typical kerbstone dimensions are:
Height: 15 cm (pedestrian walkways), 20–25 cm (vehicular roadways), 30 cm (special separation strips);
Length: 50 cm (short segments for splicing), 80–100 cm (standard segments), 150 cm (long-span segments);
Width: 10–15 cm (narrow profile), 20–30 cm (wide profile/load-bearing type).
Note: For vehicular roadways, it is recommended to select products with a height of ≥20 cm and a width of ≥25 cm to ensure adequate impact resistance.
Customization for Special Applications
For sloped or curved sections, trapezoidal cross-sections (narrower at the top, wider at the bottom) or curved splicing designs are required; individual segment lengths may be reduced to 30–40 cm to accommodate the curvature.
