Abstract
A railing component has a tubular metal body with a non-uniform cross section. The body is formed by hydroforming and has a coating applied to the exterior. A pattern is applied to the coating to simulate a wood grain. The interior of the tubular body is filled with foam and plugs are provided at opposite ends for connection to other railing components.
