Packing & supply

  • Bulk in tippers / trailers (25–32 MT)
  • Rail rake movement for large volumes
  • Jumbo bags on request

Storage & handling

  • Store on a paved, well-drained pad; avoid prolonged rain exposure to protect GCV.
  • Limit stockpile height and compact to reduce spontaneous-heating risk.
  • Blend before firing when combining GCV bands.
