Hanoi, as the political and economic hub of Northern Vietnam, has transformed into a critical epicenter for the Automotive Manufacturing and Supply Chain. With the presence of major industrial zones such as the Thang Long Industrial Park and Quang Minh Industrial Zone, the demand for high-quality Automotive Radiator Tubes has reached unprecedented levels. As Vietnam positions itself as a global hub for vehicle assembly, including the rapid rise of indigenous brands like VinFast, the necessity for reliable thermal management components is paramount.
In the surrounding provinces of Hanoi, like Hai Duong and Vinh Phuc, the concentration of Tier 1 and Tier 2 automotive suppliers has created a sophisticated ecosystem. Our radiator tubes, specifically designed for high-vibration and high-temperature environments, serve these massive assembly lines, ensuring that vehicles produced in Vietnam meet international cooling efficiency standards.
Hanoi’s subtropical climate, characterized by extreme humidity and temperatures reaching 40°C in summer, places immense stress on automotive cooling systems. Standard components often fail under these conditions. Our aluminum radiator tubes are engineered with superior corrosion resistance and enhanced heat dissipation surfaces (Dimple and Hourglass designs) to thrive in the harsh Vietnamese weather.
The city of Hanoi is leading the charge in green mobility. While traditional internal combustion engines (ICE) require robust radiator tubes, the new generation of Electric Vehicles (EVs) produced in the region requires specialized cooling for battery packs and power electronics. Our R&D department is now supplying advanced thin-wall aluminum tubes optimized for liquid-cooled EV systems.
About Us
Established in 2007, Zhejiang Rock Auto Co., Ltd. has been a leading manufacturer, exporter, and supplier of high-performance auto cooling system components. We specialize in producing a wide range of automotive cooling solutions, including radiator tubes, intercooler tubes, oil cooler tubes, as well as radiators, intercoolers, and oil coolers.
With more than 15 years of industry experience, Zhejiang Rock Auto has earned a reputation as a pioneer in the design and manufacturing of aluminum-based cooling products. We are committed to providing high-quality, cost-effective, and innovative solutions that meet the rigorous demands of our global customers. Our products are widely used in automobile, heavy industry, shipbuilding, sugar processing, packaging, navigation, molds, and other specialized applications.
At Zhejiang Rock Auto, we pride ourselves on our dedication to excellence and client satisfaction. We approach every project with a well-defined strategy, from initial design to final production, ensuring that our customers receive only the best in terms of quality and performance. Our team continuously works to enhance the efficiency of our products, driven by extensive research and development (R&D) efforts.
Our R&D unit is the cornerstone of our business, conducting detailed research and surveys to improve the performance and durability of our products. This commitment to innovation allows us to design new products with superior functionality, tailored to the specific needs of our clients. Additionally, we actively explore new applications for our cooling solutions, ensuring we remain at the forefront of the industry.
Modern production in Hanoi factories now relies heavily on High-Frequency (HF) induction welding for aluminum radiator tubes. This technology ensures a perfect leak-proof seal and thinner walls, reducing overall vehicle weight while maintaining maximum pressure tolerance.
As sustainability becomes a priority for Vietnam’s export markets (EU and USA), we utilize 3003 and 4343 series aluminum alloys. These are 100% recyclable and provide the best balance of thermal conductivity and structural strength for Hanoi-based manufacturers.
We are proud to be ISO/TS 16949 certified, and our state-of-the-art manufacturing facility is equipped with advanced technologies, including Brazing Furnaces, Fin Machines, and Core Assembly Machines. Our skilled and experienced team is proficient in all aspects of the manufacturing process, from design to final quality checks, ensuring that every product meets the highest standards.
As a customer-centric company, Zhejiang Rock Auto Co., Ltd. aims to achieve maximum customer satisfaction. We uphold the highest ethical standards in all aspects of our business and are committed to continuous improvement. Our relentless pursuit of excellence has enabled us to expand our presence globally, making us a trusted partner for businesses in Hanoi and beyond.
