Sheetal Group has launched new multi-layered Sheetal King Premium water tanks which are virtually unbreakable. Made from food-grade material, they have strong outside corners. For additional strength, ribs form an integral part of their design. The tanks are available in 500-2,000 litre capacity, and come with a 10-year warranty. Their unique threaded lid ensures they stay tightly shut and sealed. The tanks are priced at Rs 5.50-6 per litre.
