What is a Sandwich Panel? A panel with plastic, metal, paper or
other material enclosed between two
layers of a different material.
Generally, face plates may be fabricated with
stiff materials as compared to the core that is
fabricated by materials like plastics, composites
etc….

A.S. Panel
Composite (Commingled yarn
of polypropylene and fibreglass)
used as face plates.
Core material is generally
fabricated by PP Honeycomb
or Foam

Conclusion
Although it seems the A.S. Panels costs
more compared to materials like metal
and Aluminum, its lower cost for
handling, assembly, transportation and
maintenance makes it more competitive
and efficient on the market.
