For large liquid storage tanks, the preferred material of construction is carbon steel with an epoxy-based interior coating and a high-quality coating on the exterior. Non-metallic materials such as fiberglass or plastic can work well for smaller tanks that store the product at ambient temperature. However, these materials are not as durable as carbon steel, and they lose strength at high temperatures. For more information on handling and storage, you can refer to the publication Calcium Chloride: A Guide to Handling and Storage.
