Versatile Crystal Sheets for Lightweight Structures

"We used crystal polycarbonate sheets for a temporary exhibition hall in Shanghai. The sheets’ transparency and lightweight nature allowed for a quick, modular build. Despite being thin, they withstood heavy rains and winds during typhoon season. The 10mm thickness provided ample strength, and the neutral color preserved the exhibit’s lighting integrity."

Sophia Rivera
Durable Crystal Sheets for High-Moisture Environments

"In a Miami aquarium’s tunnel exhibit, Sinhai’s crystal polycarbonate sheets replaced traditional glass panels. The material’s resistance to saltwater corrosion and ease of cleaning made it ideal. The optical clarity remains unchanged after 2 years of constant humidity, providing an unobstructed view for visitors. Reliable and visually stunning."
