Zinc slab is a fundamental raw material in various industrial sectors, valued for its high purity, excellent corrosion resistance, and versatility. At Stavian Industrial Metal, we supply zinc slab produced under strict international standards to ensure consistent quality and performance. Our zinc slabs are widely used in galvanizing, alloy production, and chemical manufacturing, meeting the demands of industries that require reliability, durability, and environmental sustainability.
Zinc slab is typically produced from refined zinc with a minimum purity of 99.995%, following international standards such as ASTM B6 or ISO 752. This high purity ensures excellent performance in various metallurgical and industrial processes. Trace elements such as lead, cadmium, iron, and copper are maintained at extremely low levels to prevent contamination and ensure consistent product quality. At Stavian Industrial Metal, each zinc slab is carefully refined and tested to guarantee uniformity and reliability for downstream manufacturing applications.
A standard zinc slab has a silvery-gray metallic appearance and a relatively low melting point of around 419.5°C, which makes it ideal for casting and alloying. Its density, at approximately 7.14 g/cm³, allows it to provide excellent strength-to-weight performance. Zinc’s ability to form a natural oxide layer on its surface gives it inherent corrosion resistance, which is especially beneficial in galvanizing and other protective coating applications.
The production of zinc slab begins with the sourcing of zinc concentrates, primarily derived from zinc sulfide ores such as sphalerite. These ores undergo roasting to convert zinc sulfide into zinc oxide, followed by leaching and purification. The purified zinc solution is then subjected to electrolytic refining, where zinc is deposited on cathodes in its purest form. The resulting metal is melted, cast into molds, and solidified into uniform zinc slabs.
Casting plays a crucial role in determining the physical integrity and surface quality of zinc slab. Modern facilities, such as those operated by Stavian Industrial Metal, employ continuous casting or semi-continuous casting techniques to achieve uniform grain structure and minimize defects. Temperature control during solidification prevents internal stresses and ensures dimensional stability. Each slab is inspected for surface smoothness, edge quality, and structural soundness before packaging and shipment.
One of the most significant applications of zinc slab is in the galvanizing industry. When melted, zinc from the slab is used to coat steel or iron surfaces, forming a robust protective barrier that prevents rust and corrosion. This process extends the service life of metal structures exposed to moisture or harsh environments. Zinc slabs supplied by Stavian Industrial Metal are favored by galvanizing plants due to their high purity and consistent melting characteristics, which ensure optimal coating quality and adhesion.
Zinc slabs serve as a key raw material in the production of various zinc-based alloys, including brass (a copper-zinc alloy), zinc-aluminum alloys, and die-casting materials. These alloys exhibit desirable mechanical properties such as strength, ductility, and resistance to wear. The purity and consistency of zinc slab directly influence the performance of these alloys, making it crucial for manufacturers to source from reputable suppliers. At Stavian Industrial Metal, we tailor zinc compositions to specific industrial needs, ensuring compatibility with diverse production systems.
Beyond metallurgy, zinc slab also serves as a precursor in the chemical industry for producing zinc oxide, zinc chloride, and zinc sulfate. These compounds are used in rubber vulcanization, fertilizer manufacturing, and pigment production. In the pharmaceutical field, high-purity zinc derivatives are essential in supplements and topical formulations for wound healing and skin protection. With stringent quality assurance, Stavian Industrial Metal ensures that zinc slabs meet the purity and traceability requirements necessary for chemical-grade and pharmaceutical applications.
Global demand for zinc slab continues to rise due to the increasing use of galvanized steel in infrastructure, construction, and automotive manufacturing. As urbanization and industrialization accelerate, particularly in Asia and emerging economies, the need for high-quality zinc materials becomes even more pressing. In response, Stavian Industrial Metal maintains a strong global supply network to meet large-scale and specialized industrial orders efficiently.
Ensuring timely and reliable delivery of zinc slabs requires a robust logistics system. At Stavian Industrial Metal, we have developed comprehensive supply chain solutions that include optimized warehousing, shipping, and documentation services. Our logistics team coordinates closely with clients to manage inventory levels, ensure product traceability, and minimize transit risks.

To guarantee that every zinc slab meets industry expectations, rigorous quality control procedures are implemented throughout the production cycle. Each batch is tested for purity, composition, density, and microstructure using advanced analytical methods such as optical emission spectroscopy (OES) and X-ray fluorescence (XRF). Mechanical properties, including tensile strength and hardness, are also evaluated to confirm consistency. Stavian Industrial Metal follows international standards such as ASTM B6, EN 1179, and ISO 752, ensuring that every zinc slab complies with global specifications for both industrial and commercial use.
Traceability is essential for maintaining quality assurance in global trade. Every zinc slab supplied by Stavian Industrial Metal is accompanied by a certificate of analysis (COA) detailing chemical composition, batch number, and origin. Our internal tracking system allows customers to verify product authenticity and performance history. This transparent approach reinforces customer confidence, meeting the requirements of manufacturers that demand precision and accountability in their raw materials.
Zinc slabs are relatively stable materials, but proper handling is necessary to maintain their physical integrity and prevent surface oxidation. Warehouses at Stavian Industrial Metal are designed with climate-controlled environments that limit exposure to moisture and air pollutants. Zinc slabs are stored on wooden pallets or non-corrosive supports to avoid contact with water or reactive surfaces. Operators use mechanical lifts and protective gear to minimize handling damage and ensure workplace safety.
Proper packaging plays a crucial role in protecting zinc slabs during transport. Stavian Industrial Metal employs moisture-proof wrapping and corrosion-inhibiting materials to maintain purity and surface quality. Each shipment is securely banded and labeled for easy identification, while custom packaging solutions are available for bulk or containerized deliveries. Our partnerships with global logistics providers ensure efficient shipping routes, reduced transit times, and on-time delivery to clients worldwide.
Zinc is one of the few metals that can be recycled indefinitely without losing its essential properties. At Stavian Industrial Metal, we actively support the circular economy by integrating recycling processes into our production cycle. Recovered zinc from galvanizing residues, die-casting scrap, and electronic waste is refined and recast into high-quality zinc slabs. This closed-loop system reduces the need for virgin ore extraction, lowers greenhouse gas emissions, and contributes to more sustainable industrial practices.
Our production facilities are equipped with energy-efficient furnaces and advanced refining technologies designed to minimize fuel consumption and carbon output.
