Structure: The 50mm metal‑faced double MgO+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 5mm MgO boards (one on each side of the rock wool). Manufactured through heating, pressing, and curing processes.

Core: Rock wool (density 100 kg/m³, ≥120 kg/m³ optional) + double 5mm MgO boards · Application: High‑integrity cleanrooms, GMP facilities, hospitals, operating rooms, areas requiring enhanced fire protection and structural rigidity.
