As Stavian Industrial Metal, we recognize that special high grade zinc (SHG zinc) stands at the top tier of refined zinc classifications, defined by a minimum purity of 99.995% Zn. This exceptional purity is achieved through advanced electrolytic refining processes that eliminate trace elements such as lead, iron, cadmium, and copper. The result is a metal with remarkable stability, high corrosion resistance, and superior surface uniformity—qualities that make SHG zinc the preferred choice in industries where precision and reliability are critical.
SHG zinc exhibits a silvery-white metallic appearance, a density of approximately 7.14 g/cm³, and a melting point of 419.5°C. Its combination of mechanical strength and ductility allows for easy shaping and processing, while maintaining consistent performance under varied industrial conditions. The metal’s excellent conductivity and reactivity make it ideal for galvanizing and electrochemical applications. Furthermore, the reduced impurity levels contribute to a smoother, more durable coating layer, extending the lifespan of galvanized steel products.
From a chemical standpoint, SHG zinc’s amphoteric nature enables it to react with both acids and bases, making it a versatile raw material in various industrial and chemical processes. Its resistance to atmospheric oxidation also makes it an efficient sacrificial anode in corrosion protection systems.
The production of special high grade zinc begins with high-quality zinc ore concentrates—typically sphalerite (ZnS)—which are mined, crushed, and refined. Stavian Industrial Metal prioritizes responsible sourcing, ensuring that all raw materials meet stringent environmental and quality standards. After extraction, the ore is roasted to convert zinc sulfide into zinc oxide (ZnO) while releasing sulfur dioxide gas. This roasted oxide then serves as the feedstock for hydrometallurgical processing.
In the leaching phase, zinc oxide reacts with sulfuric acid to produce a zinc sulfate solution. This liquid undergoes multiple purification stages where impurities such as iron, copper, and cadmium are precipitated or chemically neutralized. Maintaining a controlled pH level and temperature is crucial to achieving optimal separation efficiency. The purified zinc sulfate solution forms the basis for the subsequent electrolysis process.
Electrolysis is the most critical step in obtaining special high grade zinc. During this process, the purified solution is introduced into electrolytic cells equipped with aluminum cathodes and lead-silver alloy anodes. When electric current passes through the solution, zinc ions migrate to the cathodes and deposit as a thin, high-purity metal layer. Once a sufficient thickness is achieved, the zinc sheets are removed, melted, and cast into ingots. These ingots represent SHG zinc with a purity level exceeding 99.995%, ready for use in various industrial sectors.
At Stavian Industrial Metal, we conduct thorough quality inspections at every stage of production. Each batch of SHG zinc undergoes chemical analysis, spectrometry testing, and physical inspection to confirm compliance with international standards such as ASTM B6 and ISO 752. This rigorous approach ensures consistency, reliability, and traceability for all customers across manufacturing, construction, and energy industries.
Special high grade zinc is most widely used in the galvanizing industry, where it acts as a protective coating for steel and iron surfaces. The galvanizing process—whether hot-dip or electro-galvanizing—forms a zinc-iron alloy layer that prevents rust and extends the lifespan of structural components. Stavian Industrial Metal supplies SHG zinc ingots designed for superior coating adhesion and uniformity, ensuring long-term corrosion resistance even in harsh environments.
This application is particularly vital in infrastructure, automotive manufacturing, and marine construction, where structural integrity is essential. Galvanized steel made from SHG zinc exhibits better mechanical performance, longer durability, and reduced maintenance costs compared to untreated steel.

Zinc oxide derived from SHG zinc, for example, is utilized in rubber manufacturing, pharmaceuticals, and ceramics due to its purity and chemical stability.
In the energy sector, SHG zinc plays an important role in battery production. Zinc-carbon, zinc-nickel, and zinc-air batteries rely on high-purity zinc to maintain consistent electrochemical performance and minimize degradation over time. As global demand for sustainable energy storage solutions grows, SHG zinc’s recyclability and non-toxic nature make it a preferred choice for next-generation battery technologies.
The exceptional properties of SHG zinc extend beyond its purity. Mechanically, it provides superior formability and resistance to wear, making it suitable for industrial fabrication and coating processes. Electrochemically, it serves as an efficient anode material due to its stable potential and controlled dissolution rate.
In galvanic applications, SHG zinc acts as a sacrificial metal, protecting underlying steel structures by corroding preferentially.
