Aluminum alloy/composite lightweight structural design balances strength and stiffness, integrating roof load-bearing, sealing, protection, and weight reduction to address challenges such as high energy consumption in large components, fatigue, and assembly consistency. Utilizing integrated designs like honeycomb structures, it ensures lightweight yet high-strength performance, flame retardancy, waterproofing, and extended fatigue life, while also enabling uniform floor heating. The system has achieved EN 45545‑2 HL3 fire‑retardant certification.
Product Series: Large aluminum alloy car bodies and components, aluminum alloy equipment compartments for EMUs, aluminum alloy movable roof panels, driver cabs, and more; honeycomb composite panels, green biodegradable lightweight composites, and lightweight electric‑heated flooring, among others.
Application scenarios: Lightweighting engineering requirements for locomotives, high-speed EMUs, urban rail vehicles, and regional trains, among others.
