Lightweight composite airducts


At Frank Ralphs, we developed an industry-leading lightweight composite Air Duct. Their lightweight comes from their composite foam board core, while still maintaining structural integrity within a ceiling system. We are currently supplying the Rail Car industry but this product can be adapted for other transportation and industrial applications. We’ll find the solution for your needs, so send us your project or ideas!


We currently craft a variety of Plymetal and Aluminium Honeycomb panels for the flight simulator industry. However, they can be used for any type of simulator such as needed in Marine, Rail and Entertainment Industries!
