Explore our primary machinery catalog. All models listed below are manufactured with heavy-duty structural frames and integrated OEM rocker panel systems.
Within the structural architecture of commercial vehicles—specifically class 8 heavy-duty vehicles such as Sinotruk HOWO and Shacman F3000 series—the rocker panel serves as a vital structural component. Positioned at the lower perimeter of the cabin safety cage beneath the entry doors, the rocker panel ties together the A-pillar, B-pillar, and the floor pan. Far from being a mere aesthetic trim piece, it acts as a primary load-bearing box section engineered to absorb torsional forces, survive gravel impact, and resist structural deformation during side-impact or rollover events.
In municipal and off-road mining applications, heavy trucks face severe mechanical and chemical stress. The proximity of rocker panels to the road surface subjects them to continuous mechanical bombardment from road debris, water ingress, and road de-icing salts. This exposure leads to rapid oxidative decay (rust) if the component is not designed according to exact OEM metallurgy specifications. A degraded rocker panel compromises the structural integrity of the cabin, causing misalignment of entry doors, failure of pressurized dust seals, and eventual structural failure under load.
For fleet procurement managers, sourcing replacement rocker panels based purely on unit cost often leads to premature failure. OEM rocker panels are stamped using customized progressive dies matching the original vehicle CAD data. This guarantees that all spot-welding flanges, door hinges, and wiring loom clips align exactly to within ±0.5mm tolerances. Conversely, non-OEM stamped aftermarket sheets frequently lack deep draw precision, resulting in micro-cracks in the steel matrix that accelerate corrosion.
The global demand for heavy truck cabin replacement components is driven by the growing lifespan of logistics fleets in developing economies. With the average age of heavy trucks in Africa, Central Asia, and the Middle East reaching 8 to 12 years, structural rebuilding programs have become crucial for fleet safety. As specialized manufacturers, we supply high-quality chassis assemblies and certified cabin sheet metals to ensure vehicles survive these harsh operational realities.
We utilize cold-rolled advanced high-strength steel (AHSS) sheets with tensile strength ratings up to 590 MPa. This provides superior dent resistance and structural thickness without adding unnecessary weight to the cab structure.
Our automated immersion priming applies a uniform cathodic epoxy coating (KTL/E-coat). This process coats internal box sections and hidden weld seams, passing a rigorous 1,000-hour salt spray test.
Using high-tonnage robotic stamping presses, our tooling department ensures exact replication of the complex curves and flange steps required for Sinotruk HOWO and Shacman configurations.
Founded in 2014 in Deyang City, Sichuan Province, China, Hongkai Automobile Trading Co., Ltd. began as a focused truck trading supplier in China's domestic heavy vehicle market. Through our early years, we successfully built a robust local customer network, gaining deep technical expertise in vehicle logistics, chassis structural reconditioning, and heavy-duty cabin parts fabrication.
In 2022, Hongkai’s management recognized the growing international demand for dependable heavy transport and launched a dedicated globalization strategy. We entered foreign markets, establishing partnerships with fleet owners across Africa, the Middle East, and Central Asian countries. To support this rapid export growth, we built a modern refurbishing and testing plant in 2023, expanding our engineering capabilities and setting new quality standards for structural vehicle reconstruction.
Currently, the company's headquarters is located in Shundi Auto Trade City, Deyang City, housing our modern administrative and sales office across a 15,000 square meter campus. This site also includes our specialized vehicle testing and pre-delivery inspection facility.
To support global supply chains, our primary truck assembly and body panel fabrication plant in Chengdu, Sichuan Province covers a massive 196,000 square meters. Our workforce of 186 professionals includes specialized R&D engineers, metal fabricators, paint technicians, and logistics coordinators. We also maintain a large warehousing hub, keeping a broad inventory of trucks and heavy cabin spares ready for immediate export shipping.
We operate under the core values of "Integrity, Professionalism, Innovation, and Win-Win." Integrity ensures clear contracts and transparent metal grading. Professionalism guides our dimensional design, while innovation delivers better corrosion protection. We strive for a win-win partnership, supporting global fleet operators in extending the service life of their transport assets.
Our engineering sales support guides you through initial specification reviews, steel gauge selections, custom stamping requirements, and shipping configurations. We provide 24/7 technical after-sales assistance, helping your maintenance teams with panel fitment, welding parameters, and protective painting steps.
With 20 years of hands-on experience, we understand how fleet cabins react under real-world stresses. This expertise helps us design reinforcement components that prevent early failure in demanding work environments.
Our technicians hold professional qualification certificates, ensuring that our welding, dimensional checks, and paint application follow rigorous industry standards.
We manufacture custom components tailored to your specific application requirements, ensuring precise panel fitment for custom cabs, special-purpose bodies, or older truck models.
The evolution of Hongkai Automobile Trading Co., Ltd. through a continuous expansion of facilities and capabilities.
Began selling truck chassis components. Built frontline experience working with diesel drivetrains, cabin structures, and early domestic logistics operators.
Pioneered "leasing + maintenance and support" services, successfully expanding coverage across logistics nodes in six provinces in South China.
Independently registered Hongkai Automobile Trade. Shifted focus toward high-end heavy truck configurations and built a procurement-modification-certification-after-sales service network.
Completed the 20,000 square meter Hongkai Automobile Trade City in Deyang, establishing dealership networks with leading truck brands like Sinotruk HOWO and Shacman.
Launched our dedicated delivery fleet, ensuring vehicle shipments and replacement parts reached our domestic network within 48 hours.
Expanded our global distribution network, supplying heavy-duty trucks, dump bodies, and chassis reinforcement components to fleet owners in Africa and the Middle East.
We welcome fleet managers, technical directors, and B2B distributors to audit our production and testing centers in Sichuan.
Salty marine air accelerates chemical rusting in unprotected steel components. For coastal fleets in West and East Africa, we provide rocker panels coated with high-density zinc-iron alloy coatings to resist salt-spray corrosion.
In mining operations across the Middle East, fine dust and sand wear down standard body panels. Our customized rocker panels are designed to resist abrasive wear and prevent dust from getting into the cabin.
In cold regions like Central Asia, road de-icing agents and sub-zero temperatures can make standard sheet metal brittle. We use low-temperature impact resistant steels to maintain structural strength during winter operation.
