This rail is made of ornamental metal (steel) fabricated in a shop. The railing runs horizontally to enhance the view. The members are 1/2" solids which are spaced at 4-1/2" on center so that the railing will comply with the 4" sphere rule as stated in the International Building Code. Lately, We have been going with a steel pipe as a top rail and stainless steel cables horizontally at 4" on center. It proves to be as secure and less expensive. Good luck with your project. Railings are so difficult but so important.
