AL CARTS are designed the same way as the carts used by flight attendants who appreciate the ergonomic sleekness and modern storage. The aluminum carts are light weight, green and recyclable. A piano hinge is an integral part to provide a solid door that is durable and esthetically pleasing. In manufacturing AL.CARTS, vacuum formed components are used for economy and savings that are passed to you, the customer. Surface treatment, too, is important to provide durability and corrosion protection.
