While steel water tanks are more expensive than plastic tanks, they have a much higher capacity and are more durable than plastic tanks.
Steel water tanks are perfect for customers who need to store anything from small sized tanks to much larger amounts of water. Steel tanks can hold up to 5 million litres of water, making them a better choice for irrigation, industrial and fire protection. They are more durable than plastic tanks, lasting 20+ years, due to them being resistant to the environment and the harsh African sun. Being a completely closed tank this prevent algae to grow in a steel water tank, making it a more hygienic choice, especially where for drinking water.
The wide range of sizes allows the tanks to be customized to fit the customers requirements. Compared to plastic rotor-moulded tanks which only come in specific sizes – 1 000 L, 5 000 L, 10 000 L, etc.
In summary, steel tanks are great for all uses, however budget wise they are more expensive.
