Technical Highlights & Solutions

Facing the unique challenges of the Metro & Rail project, HSST overcame multiple technical difficulties with professional expertise.

💧
Challenge
Underground Moisture Anti-Slip
Solution: Flame-textured + water-brushed composite treatment, surface roughness Ra=12.5μm. R11 anti-slip rating, friction coefficient ≥0.5 even with water. Silane water repellent on stone back, absorption <0.1%.
📳
Challenge
Vibration Environment Stone Fixation
Solution: Developed vibration-damping dry-hanging system with rubber dampers between anchors and brackets. Absorbs 10-30Hz low-frequency vibration from passing trains, panel displacement <0.2mm. 100,000-cycle fatigue test with no loosening.
🔥
Challenge
30-Second Evacuation Fire Protection
Solution: All stone passed BS 6853 fire test, flame spread index <5. Fire insulation layer behind platform wall stone. At 1200°C for 30 minutes, back temperature rise <50°C, ensuring emergency evacuation time.
