Dongfeng xinjiang truck spare parts protective plate 1301061-TLKE02Y

Built to withstand harsh off-road and hauling conditions, this protective plate features a high-strength Q355B low-alloy steel core with a 6mm thickness—delivering exceptional impact resistance against road debris, rocks, curbs, or uneven terrain. It has a minimum tensile strength of 470MPa and yield strength of 355MPa, enabling it to absorb impacts of up to 1200N (equivalent to a 120kg object falling from 1m) without permanent deformation or cracking. The plate’s surface is engineered with a concave-convex reinforcement pattern (depth: 8mm) that distributes impact force evenly across the structure, preventing localized stress fractures. Unlike thin aluminum or plastic alternatives, this steel plate effectively shields critical components (e.g., engine oil pan, transmission housing) from punctures or dents—common risks in construction sites, rural roads, or mining areas. This robust protection reduces costly repairs and extends the lifespan of undercarriage parts

Engineered to resist corrosion from road salt, rain, mud, and chemical contaminants, the protective plate features a professional three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (10μm) is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (80-100μm) with epoxy-polyester composite is baked on, forming a scratch-resistant, waterproof barrier that resists peeling or fading even after prolonged exposure to UV radiation. Finally, a clear chromate passivation layer enhances coating adhesion and chemical resistance. This system passes 1200-hour salt spray testing (per ASTM B117) with no red rust, ensuring the plate remains corrosion-free for over 8 years in coastal areas or winter roads with deicing salt. All mounting holes are coated with anti-seize compound, preventing thread rust and enabling easy removal during maintenance

Designed for efficient installation, the protective plate undergoes CNC machining to achieve strict dimensional accuracy and surface smoothness. Its length/width tolerance is controlled within ±0.5mm, and the pre-drilled holes have a concentricity error of ≤0.1mm—ensuring perfect alignment with the truck’s chassis mounting bolts. The package includes 8 galvanized M10×35 bolts, lock washers, and rubber gaskets (for vibration damping and water sealing) that match the factory thread specifications. Installation steps are straightforward: align the plate’s holes with the chassis mounting points, insert the bolts through the gaskets and washers, and tighten to the recommended torque (40N·m) with a standard wrench. No specialized tools or lifting equipment are required for most installations, and one technician can complete the process in 30 minutes or less. This easy installation design reduces labor costs and minimizes truck downtime—critical for commercial operations relying on daily transportation

Beyond shielding a single component, the protective plate is designed to support versatile use across Dongfeng Xinjiang truck applications. It is commonly used as: 1) An engine undercarriage plate—protecting the oil pan and water pump from road debris; 2) A fuel tank guard—preventing punctures to the fuel tank in rough terrain; 3) A transmission housing shield—shielding the transmission from impacts during off-road driving. The plate’s design also prioritizes maintenance accessibility: it features pre-marked access slots (if applicable) for oil drain plugs or sensor connections, eliminating the need to remove the entire plate during routine oil changes or inspections. Its lightweight yet strong structure (weight: 18kg) adds minimal load to the chassis, avoiding increased fuel consumption. This versatility makes the plate a cost-effective solution for various protection needs, reducing inventory costs for repair shops and fleet operators
