There are so many construction materials that are used in the manufacturing of barrels. All of these construction materials differ in their properties and features. The most commonly used materials are aluminum, ceramics, and stainless steel. Aluminum and ceramics are reliable but when compared with stainless steel construction material, are less reliable and less durable. Stainless steel material is considered the best in durability and longevity. Moreover, it does not require much maintenance, ensuring you do not have to spend much of your time and money on maintaining the stainless steel barrel.
