Heavy-Load Structural Solutions

Customized high‑strength box‑type welded structure, with full-working-condition strength simulation, integrates heavy‑load support for the device body, environmental adaptability and protective design, and rapid maintenance. The weld quality meets CPB standards, ensuring long‑term safety and reliable load‑bearing performance under extreme conditions.

Product Series: Heavy-load platform structure, compact heavy-load module

Application scenarios: Oil drilling, heavy equipment, etc.

Lightweight Structural Solutions

Aluminum alloy/composite lightweight structural design balances strength and stiffness, integrating roof load-bearing, sealing, protection, and weight reduction into a single solution, thereby addressing challenges such as high energy consumption , fatigue, and assembly consistency in large components. By employing 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 structure has achieved EN 45545-2 HL3 fire protection standard.

Product Series: Large aluminum alloy car bodies and components, aluminum alloy equipment compartments for high-speed trains, aluminum alloy movable roof panels, driver cabs, etc; honeycomb composite panels, eco-friendly biodegradable lightweight composites, and lightweight electrically heated floor.

Application scenarios: Lightweight engineering requirements for locomotives, high-speed EMUs, urban rail vehicles, and suburban trains.

Functional Structural Solution

By adopting an integrated design-process approach, the system incorporates visual liquid-level monitoring, alternating oil suction, automatic oil replenishment, and control interfaces, enabling visual liquid-level management, automated oil topping-up, and intelligent control for both the fuel and engine-oil systems.

Product Series: Multifunctional cabins, fuel tanks, oil tanks, and other functional structural components, as well as functional structural parts and assemblies for low-altitude applications such as unmanned aerial vehicles.

Application scenarios: Rail transit vehicles, maintenance vehicles, the low-altitude economy.
