Dongfeng NEW kinland truck parts left side roof 5701017-C0103

Built as a critical part of the NEW Kinland’s cab safety structure, this left side roof is crafted from high-strength low-alloy (HSLA) steel (Q460 grade) with exceptional impact resistance and load-bearing capacity. The 3.2mm thick steel panel undergoes hot-rolled and pickling treatment, achieving a tensile strength of 460MPa and a yield strength of 345MPa—capable of withstanding a 500kg top load (e.g., snow accumulation) without deformation. The integrated reinforcing ribs (12mm height, spaced 200mm apart) enhance structural rigidity by 40%, reducing cab vibration (≤3mm displacement at 60km/h) and improving driving comfort. In the event of a rollover, the roof maintains a minimum survival space of 500mm between the roof panel and seat cushion, complying with ECE R29 cab safety standards

Engineered to balance aerodynamic performance and functional utility, the 5701017-C0103 left side roof features a streamlined design tailored for NEW Kinland’s cab profile. The roof’s curved surface (radius 1800mm) reduces air resistance by 15% compared to traditional flat roofs, lowering fuel consumption by 3-5% for long-haul trucks (saving $1,200+ annually per vehicle). It integrates pre-formed mounting positions for roof-mounted components: a 400×300mm opening for the sunroof (Dongfeng OE 5701030-C0103) and threaded bosses for LED warning lights (common in hazardous material transportation). The roof’s edge is flanged and sealed with EPDM rubber, preventing rainwater ingress and reducing wind noise to ≤68dB inside the cab—enhancing driver comfort during extended trips

Optimized to endure harsh operating environments (rain, snow, road salt, and UV radiation), the left side roof adopts a three-layer protective coating system. The primary layer is a zinc-phosphate conversion coating (8μm thickness) for rust priming, followed by a cathodic electrophoretic coating (25μm thickness) that forms a seamless anti-corrosion barrier. The top layer is a polyester powder coating (40μm thickness) with UV-stabilized additives, resisting fading and chalking from long-term sun exposure. This coating system passes 2500-hour neutral salt spray testing (ASTM B117) with no rust or peeling, ensuring durability in coastal areas and snowy regions. The inner surface is coated with sound-absorbing paint (10μm thickness), reducing noise transmission from the roof by 20%

This left side roof is designed for efficient installation and long-term cost savings for Dongfeng NEW Kinland operators. Its 16-point flange design and pre-drilled mounting holes enable installation by a 2-person team in 4 hours—30% faster than aftermarket roofs with mismatched holes. The OE-compatible design eliminates the need for welding modifications (which weaken the cab structure and increase repair costs by 50%). By maintaining cab structural integrity, it prevents water leaks that cause interior damage (e.g., mold growth, electrical system failure—repair costs up to $800). The high-strength steel and durable coating extend service life to ≥500,000km—twice that of low-quality replacement roofs. Backed by a 2-year/200,000km Dongfeng warranty, it provides reliable cab protection and predictable maintenance expenses for fleet operators
