Product overview
Versatile calcium sulphate for construction, agriculture and manufacturing
Gypsum is calcium sulphate dihydrate, CaSO₄·2H₂O. Its natural crystalline water, workability and high calcium sulphate content make it essential in cement, plaster, soil treatment and industrial processing.
Our gypsum is selected for purity and consistency. Defined quality controls help keep chemistry stable from the first ton to the last, protecting downstream operations from mixed or unpredictable supply.
Each consignment is matched to the required grade and size and supported by documented chemistry.
Origin and sourcing
Trusted regional deposits with low impurity levels
Established deposits and direct quality control support stable chemistry, steady volumes and documented consignments.
Consistent Supply
Reliable source base for spot orders and long-term contracts.
Verified Chemistry
Each consignment is documented for procurement and process control.
