Non-Corrosive Security Railing A security railing formed from plastics material pipe which is lightweight, low cost, and non-corrosive. The top railng and preferably the posts of the security railing are formed of double pipe construction comprising a first pipe and a second pipe inside the first pipe, the second pipe having an outside diameter related to the inside diameter of the first pipe. The first pipe is of plastics material and the second pipe preferably also is of plastics material. A lower railing utilises a plastics 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, and these T connectors and cross connectors are of the same outer dimension as the first pipe to give the railing a smooth contour. A plurality of holes in the lower surface of the upper railing and the upper surface of the lower railing permit the insertion of smaller diameter plastics 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 under test loads. The plastics material used is preferably polyvinyl chloride. |
