Galvanized Steel Composite Panel Overview

This series blends durability, magnetic versatility, and visual smoothness. It’s built from two galvanized steel skins fused to a polyethylene core — a tough, balanced structure that stays rigid yet easy to handle. Each side has a clean, even coating, ready for printing or dry-erase use. They’re offered as digital/digital or digital/whiteboard options


Core Features



  • Strong steel layers. Both faces use galvanized steel for strength and anti-corrosion reliability.

  • Smooth digital finish. Prints look crisp, colors stay true, surface stays flat.

  • Magnetic receptive. Great for attaching charts, displays, or teaching tools.

  • Self-supporting. It holds shape well without extra framing.

  • Dual coatings. Each side can have a different purpose — print one, write on the other.

  • We like how it feels solid but not heavy. You can mount it, print it, or turn it into a dry-erase board easily.
