Abstract
A plastic covered article for a railing which includes an elongate core encased in a seamless, plastic casing. The casing is heat shrunk to conform with the exterior surface of the core. The core is thereby covered along its length with a weather-resistant casing which requires no periodic field maintenance. The railing articles of the present invention are fabricated by heating a tube of plastic material and causing the tube to expand. The elongate core is inserted into the expanded tube to encapsulate the core. The tube encapsulating the core is again heated to shrink the tube tightly against the core such that the tube conforms to the exterior surface of the core.
