Dongxin Chemical supplies 4N zinc granules produced from high-purity 0# distilled zinc ingots provided by Huludao Zinc Industry Co., Ltd. These ingots have a purity of 99.995% and are manufactured in strict compliance with the national standard GB/470-2008. The resulting zinc granules have a bright surface, a dense structure, and are free from inclusions.
Throughout the production process, from zinc ingots to zinc granules, we implement stringent controls to ensure no contaminants are introduced and to avoid contact with other metals. We utilize advanced testing equipment, including the DF-100 direct-reading spectrometer and plasma inductively coupled atomic emission spectrometer, to conduct comprehensive quality inspections on each batch of zinc granules. Every stage of production is meticulously monitored to ensure no detail is overlooked, thereby achieving consistent product performance and stability.

Electroplated Steel Sheets
- Corrosion Resistance: Zinc granules are used in the electroplating process to coat steel sheets. This zinc coating provides superior corrosion resistance, making the steel sheets suitable for use in environments exposed to moisture and corrosive elements.
- Durability Enhancement: The zinc layer enhances the durability and longevity of steel sheets, protecting them from rust and extending their service life.
Automotive Tire Steel Cord
- Strength and Flexibility: In the automotive industry, zinc granules are employed in the electroplating of steel cords used in tires. The zinc coating improves the adhesion between the steel cord and rubber, enhancing the overall strength and flexibility of the tire.
- Enhanced Performance: The electroplated zinc layer contributes to better performance and reliability of tires, making them more resistant to wear and tear.
Fasteners and Hardware
- Protection and Longevity: Zinc granules are used in the electroplating of fasteners such as bolts, nuts, and screws. The zinc coating provides effective protection against corrosion, ensuring that these components maintain their integrity and functionality over time.
- Improved Aesthetics: Electroplated zinc also enhances the appearance of fasteners and hardware, giving them a smooth and shiny finish that is both attractive and resistant to environmental damage.
