Structure: The 50mm metal‑faced double MgO + aluminum honeycomb manual sandwich panel consists of pre‑painted steel or stainless steel facings, edges sealed with galvanized steel strips and corner pieces. The core is aluminum honeycomb + double 5mm MgO boards (one on each side). Manufactured through heating, pressing, and curing processes.

Core: Aluminum honeycomb (cell diameter 21 mm, <21 mm optional) + double 5mm MgO boards · Application: Cleanrooms, laboratories, electronics manufacturing, areas requiring high flatness, light weight, and good fire resistance.
