Dongfeng GX Urea Tank Assembly Guard 1205541-T69L0

As a core protective component for the SCR system’s urea tank, this guard is designed to withstand high-impact forces and road debris damage common in heavy-duty truck operations. It is constructed from 1.5mm-thick cold-rolled steel (Q235 grade) with a reinforced perimeter frame (cross-sectional thickness of 3mm) and multiple longitudinal support ribs, achieving a static load-bearing capacity of ≥500 kg and an impact resistance rating of 20 kJ—sufficient to shield the urea tank from gravel, curbs, or minor collisions during loading/unloading. The guard’s open-grid design (30mm × 30mm mesh size) balances protection with weight reduction (total weight: 4.2 kg) and allows for airflow to prevent urea solution overheating, while blocking large debris (≥10mm) that could puncture the tank or damage sensors

Engineered to endure harsh operating environments (road salt, rain, humidity, and temperature extremes), the guard features a multi-layer anti-corrosion coating system. The steel substrate undergoes a zinc phosphate pretreatment (thickness ≥5μm) to enhance coating adhesion, followed by a cathodic electrophoretic paint layer (thickness ≥20μm) and a top coat of high-gloss polyester powder coating (thickness ≥8μm). This triple-layer protection achieves a salt spray resistance rating of ≥1,000 hours (per ASTM B117), preventing rust and corrosion even in coastal or winter regions where road salt is heavily used. The coating is also UV-stabilized, resisting fading and chalking from prolonged sunlight exposure (passing 1,500 hours of accelerated weathering testing per ISO 4892), ensuring long-term aesthetic and structural integrity

The guard is designed with user-centric accessibility to simplify urea tank maintenance, a critical feature for commercial truck operators. It includes two quick-release stainless steel latches on the side, allowing technicians to remove the guard in ≤2 minutes without tools—eliminating the need to disassemble mounting bolts for routine tasks like urea refueling, sensor inspection, or tank cleaning. The guard’s top edge is rounded (radius: 5mm) to prevent injury during maintenance, while strategically placed cutouts align with the urea tank’s (diameter: 50mm) and sensor connectors, enabling direct access to these components without removing the entire guard. Additionally, the guard’s lightweight design (4.2 kg) reduces operator fatigue during installation or removal

This urea tank assembly guard meets strict domestic and international standards for SCR system components and automotive safety. It complies with GB/T 3847 (China National Standard for Diesel Vehicle Exhaust Aftertreatment Systems) , ISO 22241 (International Standard for Diesel Engine Urea Solution and Related Components), and Dongfeng’s internal Q/DF 045-2024 specification for urea system protective parts. Each unit undergoes rigorous factory testing, including: a load-bearing test (sustaining 500 kg for 24 hours without deformation), an impact test (20 kJ impact with no structural failure), a corrosion resistance test, and a dimensional accuracy inspection using 3D scanning. These certifications ensure the guard does not interfere with the SCR system’s performance (e.g., no blockage of urea flow or sensor signals) and meets global emission regulations, making it suitable for Dongfeng GX trucks operating in China, the EU (ECE R49 standard), and Southeast Asia
