Dongfeng Xinjiang white cab shell 50M14-C43S6 in stocked

Crafted from automotive-grade high-strength low-alloy (HSLA) steel (grade Q345) with a minimum tensile strength of 345MPa, the 50M14-C43S6 cab shell offers exceptional structural rigidity and impact resistance—critical for heavy-duty truck operations in harsh environments (e.g., construction sites, long-haul highways). The shell undergoes a multi-step manufacturing process, including robotic welding (ensuring weld strength and uniformity) and shot blasting (removing surface rust and impurities to enhance coating adhesion). Key stress-bearing areas, such as the front anti-collision beam interface and roof support pillars, are reinforced with additional steel plates (thickness increased from 1.5mm to 2.0mm), providing enhanced protection for drivers in the event of minor collisions or rollovers

The cab shell features a high-performance automotive-grade white coating system that meets Dongfeng Xinjiang’s strict aesthetic and protective standards. The coating process includes three layers: a cathodic electrophoretic primer (for corrosion resistance), a high-build intermediate coat (for surface smoothness), and a matte or glossy topcoat (depending on customer requirements) in a standard “Dongfeng White” (Pantone 11-4810 TPX) shade. This coating system delivers excellent weather resistance, withstanding prolonged exposure to UV radiation (passing 1000-hour xenon lamp aging tests without fading), extreme temperatures (-40°C to +80°C), and chemical contaminants (e.g., road salt, diesel fuel). Additionally, the surface is scratch-resistant (meeting ISO 15184 standards for pencil hardness ≥ 2H) and easy to clean, maintaining a professional appearance even after long-term use

The 50M14-C43S6 cab shell is pre-machined with precise interfaces to accommodate all essential cab components, streamlining the assembly process for manufacturers or maintenance teams. These interfaces include: pre-drilled holes for windshield and side window installation (with rubber gasket grooves to prevent water leakage), threaded holes for door hinges and latches (ensuring door alignment and smooth opening/closing), and mounting brackets for the instrument panel, seat rails, and HVAC (heating, ventilation, and air conditioning) system. All holes and brackets are positioned with a tolerance of ±0.5mm, ensuring that OE components (e.g., Dongfeng Xinjiang’s original windshield, door locks) fit perfectly without adjustments. This precision also reduces the risk of post-assembly issues such as air or water leaks, which can affect driver comfort and cab longevity

Despite its high-strength construction, the 50M14-C43S6 cab shell incorporates a lightweight design to improve the vehicle’s fuel efficiency and payload capacity—key considerations for heavy-duty truck operators. The HSLA steel material is strategically used: thinner steel (1.2mm-1.5mm) is applied to non-stress-bearing areas (e.g., rear cab panels), while thicker steel is reserved for critical structural parts. Additionally, the shell features a streamlined shape (with a drag coefficient of approximately 0.58) that reduces air resistance during highway driving, further contributing to fuel savings. The overall weight of the cab shell is approximately 320kg (for a standard single-row configuration), which is 8-10% lighter than traditional carbon steel cab shells of the same size—without compromising on strength or safety. This lightweight design helps Dongfeng Xinjiang trucks meet increasingly strict fuel efficiency regulations while maintaining their heavy-haul capabilities
