Durable Polycarbonate Domes for Stunning Architectural Designs

"Sinhai’s polycarbonate dome was the perfect choice for our botanical garden in Singapore. The 8mm hollow sheets provided excellent light transmittance and thermal insulation, creating an ideal environment for tropical plants. The curved design was easy to install, and the UV-resistant coating has kept the dome clear and vibrant for 3 years. Highly impressed with the structural integrity and aesthetic appeal."
