Built with Aluminum & HDPE Technologies
This truck topper combines the strength of heavy-duty aluminum with the durability of marine-grade HDPE to create a structure that’s both tough and lightweight. Aluminum provides rigid support and secure mounting, while HDPE absorbs impact, resists moisture, and eliminates corrosion and rot.
Together, these materials are engineered to handle vibration, temperature changes, and constant outdoor exposure—resulting in a topper that stays solid, quiet, and dependable through years of hard use.
