Verified Project Case — 2025
Indonesia Industrial Factory – PU-Edge Rock Wool Roof Panels
Project Overview
Project Overview
LIAOHE supplied PU-edge-sealed rock wool roof panels for an industrial factory building in Indonesia in 2025. The project required panels with confirmed fire-retardant rock wool cores, polyurethane edge sealing to protect against moisture ingress, and PVDF coating for long-term corrosion resistance in a tropical environment. Panels were manufactured, quality-checked, and shipped to Semarang port in 13 × 40HQ containers.
