Structure: The 75mm metal‑faced double gypsum + rock wool manual sandwich panel consists of pre‑painted steel or stainless steel facings, edges sealed with galvanized steel strips and corner pieces. The core is rock wool + double 9.5mm gypsum boards (one on each side). Manufactured through heating, pressing, and curing processes.

Core: Rock wool (density 100 kg/m³, ≥120 kg/m³ optional) + double 9.5mm gypsum boards · Application: Cleanrooms, hospitals, pharmaceutical plants, high‑fire‑risk areas, partitions requiring enhanced fire resistance and thermal insulation.
