Product Overview

Sandwich panels are a durable, economical, modular building material used to cover buildings and structures. It can be used as a fireproof, waterproof, heat-insulating, and noise-reducing decorative material for exterior walls. It is lightweight, impact-resistant, and formaldehyde-free, providing green and environmentally friendly protection and decoration for buildings.

Sandwich Panels Overview

These panels are made of two layers of pre-coated steel plates and polyurethane insulation. The surface is high-quality color embossed veneer metal sheets, providing strength and rigidity. The middle layer is a rigid high-density polyurethane foam insulation treated with flame retardant. The bottom layer is an aluminum foil protective layer for moisture-proof functions.
