What I'm trying to do is compare pipe to channel as far as lateral strength. I have just received a patent, 7,707,794. It's for a building system of walls, fences, and buildings using steel channels and pipe posts. The current way to build a high security fence using expanded metal panels depends upon old chain link fence brackets and framework. I believe my system provides not only a simpler and easier to build framework, it's stronger. Here's my logic. Pipe is strong three hundred and sixty degrees. That is a good thing when building a framework for chain link fence. Chain link is a woven fabric and needs to be supported not only laterally but vertically so pipe works best. Expanded metal on the other hand doesn't require vertical support. In fact it can provide vertical support for the framework, a sheet of expanded metal is stronger than it's parent shape as a sheet. My system uses C channel or purlin oriented horizontally. I get the benefits of the purlin or channel's greatest strength where its needed the most for expanded metal support. What I need is a comparison reflecting that advantage over the use of pipe in chain link fence framework. 2" X 4" fourteen gauge channel versus 1 1/4 schedule forty pipe. I'm attaching some photos to give you an idea what I'm talking about. I appreciate any help possible. I can make things but then I need help explaining it, darn.
