Types of Sandwich Panels Based on Outer Skins

The outer layers (skins) provide strength and protection. Common materials include:

• Metal Skins:

  • Galvanized Steel: Durable and corrosion-resistant.

  • Aluminum: Lightweight and rust-resistant.

  • Stainless Steel: High corrosion resistance, used in harsh environments.

• Composite Skins:

  • Fiberglass-reinforced plastic (FRP).

  • Carbon fiber (for high-performance applications).

• Other Materials:

  • Plywood or MDF (for lightweight structural applications).

  • Cement board (for fire-resistant applications).
