Competition in polymer‑sheet industry centers on process and structural innovation. Zhejiang Saining New Material keeps upgrading polycarbonate‑sheet technology, focusing on two flagship products for large‑scale glazing projects: PC honeycomb sheets and U‑lock interlocking hollow sheets.

The honeycomb lattice structure improves wind‑pressure resistance, impact performance and thermal insulation under equal weight, ideal for large‑span skylights and intelligent greenhouses. U‑lock sheets adopt improved interlocking joints, simplify on‑site installation and reduce water‑leak risks, widely applied for factory rooftops and commercial‑complex glazing roofs.

Our in‑house lab conducts regular tests on light transmittance, impact strength, UV‑aging performance and flame retardancy to guarantee consistent quality. R&D team develops modified formulas for high‑UV tropical zones, cold‑snow‑prone regions and other working conditions. Besides PC series, we also optimize acrylic sheets and PETG films for lighting, advertising display and packaging sectors.
