Shapes aluminum fence sets the standard in aluminum fence specifications. Be sure to check the thickness of our post and our rail and pickets, we have not only the thickest pickets and rails in the industry we have the strongest. Alumium is a softer metal and it needs to resort to some sort of a standard. If you need a more detailed drawing or specification of a specific aluminum fence rail or post please email us and we will get you any specifications that you need. We are not afraid to show you what our aluminum fence is made out of, in fact we are proud of our specifications so we list them online.
