As an accredited Zinc Ash factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Zinc Ash is packaged in durable, moisture-resistant 50 kg HDPE bags, securely sealed and clearly labeled for industrial use and safety. |
| Shipping | Zinc Ash is shipped in sealed, moisture-resistant bags or drums, typically lined with polyethylene. Containers must be clearly labeled and handled as non-hazardous, but kept dry to prevent chemical reactions. Transport should comply with local safety regulations, ensuring containment to avoid spillage and environmental contamination during transit. |
| Storage | Zinc Ash should be stored in sealed, labeled containers in a cool, dry, and well-ventilated area away from moisture, acids, and incompatible substances. The area should be protected from physical damage, sparks, and open flames. Proper containment prevents dust dispersion and environmental contamination. Ensure storage complies with local regulations, utilizing non-combustible shelving and readily accessible spill containment measures. |
