Alustep® HFR is a sandwich panel used as support for natural stones. This panel combines exceptional strength with lightweight, making it ideal for applications that require high performance and great durability.
IMO MED certification is one of the strengths of the HFR Sandwich Panel. In fact, it achieved Mod. B and D and the US Coast Guard. This means that the product has been rigorously tested and approved to the highest standards set by the International Maritime Organization (IMO), ensuring compliance with fire reaction regulations for ships and vessels.
Alustep® HFR is a sandwich panel composed of a honeycomb aluminium core and two fiberglass skins impregnated with epoxy resin. It is the most robust of the Alustep® series panels has good fire reaction properties.
