Foam Core Aluzinc Sandwich Panels

The foam core aluzinc sandwich panel is a new type of composite material. The surface coating of aluzinc is aluminum-zinc alloy. The foam core material supplied by TOPOLO is high-quality closed-cell foam such as XPS, PU, PET, PU, and EPP.

The advantages of the Aluzinc sandwich panel are obvious.

  • Galvalume steel has good high strength, heat resistance and corrosion resistance.
  • Closed-cell foam has good thermal insulation, waterproof and moisture-proof properties.

What is aluzinc (galvalume) steel?

Galvalume steel is a pre-coated steel obtained by hot-dipping a layer of Al-Zn coating on both sides of cold-rolled steel with various strengths and thickness specifications. Its surface coating is 55% aluminum, 43.4% zinc and 1.6% Silicon alloy composition. The surface is characterized by smooth, flat and gorgeous spangles.

Surface Treatment

In order to obtain better corrosion resistance and a more beautiful appearance, the surface of aluzinc steel will be pre-coated.

  • Color: RAL series
  • Paint: PE, SMP, HDP, PVDF

Closed Cell Foam Core

The closed-cell foam board provides a reliable guarantee for light weight. It is not only light in weight, but also has good thermal insulation, waterproof and moisture-proof performance.


As a composite material with high-cost performance, foam core aluzinc sandiwch panels has a wide range of applications. It can be used in buildings, RVs and trucks as wall panels, roofs, ceilings, partitions, etc.
