Core Substrates

To learn more about the core substrates used in aluminum honeycomb panels and other building panels, call (303)664-9601 or visit www.flatironpanelproducts.com.

Flatiron Panel Products works with a wide variety of core substrates, specializing in aluminum honeycomb for varying applications. Aluminum honeycomb cores can be produced in a variety of ways.
This is an internal aluminum honeycomb core substrate shown without aluminum face sheets. Core substrates are the foundation of panels. This core is comprised of ¼” aluminum honeycomb with a 3003 aluminum alloy grade. The hexagonal cell are a 1/4” in diameter. This is a structural grade aluminum honeycomb core used for emergency vehicle flooring, commercial trailers, and structural wall cladding. ¼” aluminum honeycomb core is strong and rigid while maintaining the lightweight feature. This core is cut to size at 1-¾” thick and is ready to be bonded to make an aluminum honeycomb panel. Aluminum honeycomb core can range in thickness from ⅛”-6” and is cut to precise dimensions, within .005 of an inch. Aluminum honeycomb core provides the highest rigidity, while maintaining the lightweight feature of any substrate available.
⅜” aluminum honeycomb core is also lightweight and rigid. ⅜” cell core is the most common substrate overall, meeting the majority of strength and weight requirements, while being fairly cost effective. Aluminum honeycomb cores are impervious to extreme temperatures, ranging from below zero up to 350 fahrenheit. Aluminum honeycomb is also resistant to moisture, corrosion, fungi, and is A+ fire-rated. Cores can be perforated to allow airflow through the panel while maintaining strength requirements; vacuum tables and industrial machine parts typically benefit from this feature.
This is an example of an aluminum honeycomb core bonded to a transparent polycarbonate face sheet, which demonstrates the even bond line. Polycarbonate panels are dent and moisture resistant.
Polyiso foam core is a closed cell substrate that is water and fire resistant. Polyiso foam core can be used in internal or external panels due to the R factor. It is commonly used for external cladding in commercial buildings, elevator cabs, and the marine industry. Polyiso foam core is also rigid while being lightweight, and fire, water, and fungi resistant.
Aluminum plywood panels are used for heavy duty, high impact applications such as: high traffic ramps, bridges, and areas that require high strength without weight requirements or concerns. Aluminum plywood core allows 100% of the core to be bonded, providing the strongest bond possible, being dent resistant, with a sleek aluminum look.
Polypropylene panels are made up of plastic honeycomb and are popular in the boating industry and other places where water-friendly paneling is required. The this core allows panels to be submerged in water and will not warp in humid or watery conditions.
As the most cost effective and lightweight option, paper honeycomb core is used in standard interior doors, shelving and partitions.
