Product Detail
As the global construction industry moves towards prefabricated, green, and industrialized construction, metal surface sandwich panels with their advantages of lightweight, high strength, energy efficiency, environmental friendliness, and rapid installation, have become one of the most widely used building envelope materials in modern industrial buildings, commercial buildings, and cleanroom projects.
Metal surface sandwich panels are composed of a metal face panel and a core material with different properties. They not only possess excellent structural strength but also offer multiple properties such as thermal insulation, fire resistance, moisture resistance, sound insulation, aesthetics, and durability, meeting the diverse needs of different countries and industries for building envelope systems.
What are Metal Surface Sandwich Panels?
Metal-faced sandwich panels typically consist of three parts:
- An outer layer of high-strength color-coated steel sheet or aluminized zinc-coated steel sheet
- A middle functional core material
- An inner metal face panel
Through a continuous composite production process, different core materials are firmly bonded to the metal sheet, giving the panel multiple functions simultaneously, including load-bearing, enclosure, thermal insulation, and decoration.
Based on the core material, metal surface sandwich panels can be divided into:
- Metal-faced rock wool sandwich panels
- Metal-faced foam sandwich panels
- Metal-faced magnesium oxide sandwich panels
- Metal-faced silicate rock sandwich panels
Different products are suitable for different building types and usage environments.
