Product Details

Seismic-Proof Roofing System

Seismic-proof roofing system employs flexible alloy steel (0.45mm, elongation 22%) and shock-absorbing brackets that allow 150mm horizontal displacement during quakes. Tested to Japanese JIS A 5021 standard, it withstands 9.0-magnitude tremors without collapse—proven in Chile’s 2023 quake with zero structural failure. The stone layer uses flexible epoxy resin to prevent granule shedding under vibration, while PVC backing dampens resonance by 30 dB.
