Protean’s HC-220 Laminated Honeycomb Metal Wall Panels offer perhaps the flattest wall panel system available in the market today. The skins are laminated in our unique dead flat platen vacuum press using either kraft-paper honeycomb core or aluminum honeycomb core ensuring extreme flatness and greater composite strength. In addition to the phenomenal strength of the composite panel, the product is extremely light weight, the average Protean laminated wall panel weighs approximately 2 pounds per square foot significantly reducing the size, weight and cost of the supporting structure.

HC-220 Series Metal Wall Panel Systems are designed and installed utilizing a combination of our “rainscreen” principle panel system and gasket at the joints of the panel. The tongue and grove joint enables the metal wall panels to be installed both horizontally and vertically using concealed fasteners. When installed in the horizontal position, the joint system with interlocking tongue and groove, which provides a natural method of shedding water preventing the water from penetrating the exterior skin of the building.

The exterior panel skins are formed on press brakes, ensuring crisp lines and offering greater dimensional flexibility, while the interior liner skins are roll-formed, increasing productivity. The skins and the cores are then laminated on a dead flat platen vacuum press table ensuring extreme flatness and greater strength. This system offers an excellent means of obtaining custom insulated wall panels.

Typically fabricated at a thickness of 2″, the honeycomb core metal wall panels are also available 1” up to a thickness of 6″. Metal wall panel widths are available up to 54 3/4″ based on the 2” panel thickness available in as many different sizes as the project requires at the same competitive price. This system offers an excellent means of obtaining custom aluminum wall panels.
