Uneven heat expansion produces an anti-slip,-like texture. 

​​Production Process​​:

Cut raw granite into slabs. Initial grinding → Flame treatment (800–1,000°C) using a (20–40 mm distance, 120–250 mm/s speed). Pre-spray water prevents cracking; removes 0.5–1 mm surface layer. ​​Result​​: Natural, rustic appearance ideal for sidewalks, roads, and interior/exterior walls. ​​Road Curb Stones ​ ​​Function​​: Demarcates roads, sidewalks, and green belts to ensure traffic safety and edge neatness. ​​Classifications​​: ​​Material​​: Concrete vs. Stone curbs. ​​Profile​​: H-type, T-type, R-type, F-type, TF vertical, P flat. ​​Alignment​​: Straight or curved (compatible with flamed slabs).
