Dongfeng xinjiang truck parts Lower protective plate 1301064-TLKE02Y

Built to withstand off-road hazards and heavy-haul stress, this lower protective plate features a Q355B low-alloy high-strength steel core with 7mm thickness—delivering exceptional impact resistance. It has a minimum tensile strength of 470MPa and yield strength of 355MPa, enabling it to absorb impacts of up to 1500N (equivalent to a 150kg object falling from 1m) without deformation or cracking. The plate’s surface is engineered with a concave-convex reinforcement pattern (depth: 10mm) that distributes impact force across the structure, preventing localized damage to the oil pan or transmission. Unlike thin aluminum alternatives (which dent easily), this steel plate resists punctures from rocks, curbs, or debris—common risks in construction sites, mining areas, or rural roads. This robust protection reduces costly repairs and extends the lifespan of undercarriage components by 50% compared to unprotected setups

Engineered to resist corrosion from mud, rain, road salt, and chemical contaminants, the protective plate features a professional three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (12μm) is applied to the steel surface to block rust at the substrate. Then, a high-temperature electrostatic powder coating (90-110μm) with epoxy-polyester composite is baked on, forming a scratch-resistant, waterproof barrier that resists peeling even after prolonged exposure to UV radiation. Finally, a clear chromate passivation layer enhances coating adhesion and chemical resistance. This system passes 1500-hour salt spray testing (per ASTM B117) with no red rust, ensuring durability for over 10 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 oil changes or chassis maintenance

Designed for efficient installation, the lower protective plate undergoes CNC cutting and bending to achieve strict dimensional accuracy (length/width tolerance: ±0.5mm). The pre-drilled holes have a concentricity error of ≤0.1mm, ensuring perfect alignment with the chassis’ mounting bolts. The package includes 10 galvanized M12×40 high-strength bolts (grade 10.9), lock washers, and rubber gaskets—these gaskets provide vibration damping and prevent water from seeping into the chassis. Installation steps are straightforward: align the plate’s holes with the chassis brackets, insert the bolts through the gaskets and washers, and tighten to the recommended torque (55-60N·m) with a standard wrench. No specialized lifting equipment is needed for most installations, and one technician can complete the process in 40 minutes or less. This easy installation design reduces labor costs and minimizes truck downtime—critical for commercial operations relying on daily transportation

Beyond basic protection, the lower protective plate is optimized for practical chassis maintenance and versatile use. It features pre-marked access panels (with removable bolts) for oil drain plugs and transmission fluid checkpoints—eliminating the need to remove the entire plate during routine oil changes (saving 30 minutes of maintenance time). The plate’s weight (22kg) is balanced to avoid adding excessive load to the chassis, ensuring no impact on fuel efficiency (tested to increase fuel consumption by less than 0.5L/100km). Additionally, it can be used as a secondary mounting point for aftermarket accessories like skid plates or recovery points (via pre-drilled auxiliary holes). This versatility makes it suitable for various applications—from long-haul highway driving (protecting against road debris) to off-road construction work (shielding from rocks and uneven terrain)—meeting the diverse needs of Dongfeng Xinjiang truck owners
