Sandwich board English name: laminboard
The sandwich panel product is composed of two layers of formed metal panels (or other material panels) and a polymer insulated inner core that is directly foamed and matured in the middle of the panel. These sandwich panels are easy to install, lightweight and efficient. The filling system also uses a closed-cell molecular structure to prevent condensation of water vapor. The formation of the outer steel sheet fully considers the structural and strength requirements, and takes into account the aesthetics. The inner surface layer is formed into a flat plate to meet various needs.
