Our Zinc product collection offers a complete range of Zinc Sulphate designed to meet diverse agricultural and industrial needs with uncompromising quality and purity. We manufacture Zinc Sulphate Monohydrate in powder, coarse powder and granulated forms for precise application, a highly soluble Zinc Sulphate Heptahydrate, and high-purity Zinc Metal, so buyers can source the right grade and form for their process from a single manufacturer.
Available in 33% and 35.5% zinc grades and in three physical forms: fine powder, coarse powder and granulated (granular). The 33% grade carries a minimum 33% zinc and minimum 15% sulphur; the 35.5% grade carries a minimum 35.5% zinc and minimum 17% sulphur, with controlled limits on cadmium, lead, arsenic and mercury. All forms are freely soluble in water, with a pH of 4.0 to 5.5 in a 5% aqueous solution.
Supplied as colorless to white crystals in 21% and 22% zinc grades, valued for high solubility and purity. The 21% grade carries a minimum 21% zinc and 10% sulphur; the 22% grade a minimum 22% zinc and 10.5% sulphur. Both are freely soluble in water and well suited to fertigation, foliar and chemical applications.
High-purity Zinc Metal of 99% minimum purity, supplied as ingots. With a melting point of 419.5 degrees Celsius and an atomic weight of 65.38 g/mol, it is used in galvanization of steel and iron, die-casting, alloy manufacturing such as brass, and as a chemical raw material.
