Abstract: A security railing formed from polyvinyl chloride pipe which is lightweight, low cost, and non-corrosive. The top railing and the posts of the security railing are formed by laminating a first pipe and a second pipe, the second pipe having an outside diameter essentially equal to the inside diameter of the first pipe. The laminated railing is utilized for posts and the top railing of the security railing. A lower railing utilizes a polyvinyl chloride pipe having the same outside diameter as the laminated top railing. T connectors and cross connectors are used at the joints between the upper and lower railings and the posts. A plurality of holes in the lower surface of the upper railing and the upper surface of the lower railing permit the insertion of small diameter polyvinyl chloride pipe sections at closely spaced intervals to provide vertical railing elements. The security railing meets requirements of national building codes and will not permanently deform from loads.
