A security railing formed from plastics material pipe which is lightweight, low cost, and non-corrosive. The top railing 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 utilizes a plastic 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.

A security railing comprising: a plurality of railing sections, each of said sections formed from an outer, plastics pipe having an outside dimension and an inner dimension and a second pipe, said second pipe having an inside dimension and an outside dimension essentially equal to the inside dimension of said first pipe, said second pipe inserted into said first pipe so that a portion of the second pipe projects beyond one end of the first pipe; a plurality of posts having upper and lower ends, each formed from one of said railing sections; a plurality of horizontal top rails, each formed from one of said railing sections; T-shaped connector bodies between and connecting adjacent ones of said top rails and posts said connector bodies each having an inner bore essentially equal to the outside dimension of the second pipe and receiving said projecting portions of the second pipes of said connecting adjacent ones of said top rails and posts and an outside dimension essentially equal to the outside dimension of the outer pipe whereby the connector body forms smooth continuations of the outer pipes of said top rails and posts.
