Aluminum is a relatively recent, modern addition to the list of materials used for furniture, however it has become enormously popular as the material of choice for commercial furniture in recent years. Aluminum is an abundantly available metal and it is lightweight and possesses many advantages over other metals used for furniture manufacture. Outdoor furniture made from tube steel is prone to rust even when carefully vinyl coated or stove enameled. These coatings can chip and degrade eventually meaning that steel furniture always eventually rusts. These barstools also have the benefit of being stacked meaning that they can be stored away conveniently at the end of the day.
