Zinc Water Tanks – Premium Long-Lasting Water Storage


Rainbow Tarps and Linings have partnered with a leading corrugated-tank manufacturer to deliver South Africa’s most durable zinc water tanks — combining 20+ year lifespans with various liner options to meet the needs of Africa’s agricultural, mining and domestic sectors.


Why Choose Zinc Over Plastic?
  • UV-resistant – won’t crack or become brittle like roto-moulded tanks.
  • Hygienic – prevents algae growth (solid galvanised top).
  • Potable-safe – certified 620-micron liner for human drinking water.
  • Aesthetic – sleek corrugated zinc finish.
