Aluminum honeycomb is a lightweight but very strong structural material composed of aluminum sheets assembled to form a honeycomb-like structure. This type of material is often used in industries such as transportation (airplanes, ships and in trains in order to reduce weight), automotive and construction for its exceptional mechanical properties, finding use for a wide variety of industrial and design applications where the combination of light weight, strength and performance is essential. Another key feature is the flatness, guaranteed by the production method, even on very long panels (up to 15 m), a characteristic that architects like in order to have absolutely defect-free surfaces.
