General
All parts that are needed to build the hex beam are provided below. Stainless steel is recommended although it is considerably more expensive. For example, stainless steel U bolts cost more than twice the cost of zinc U bolts. The sources for steel parts here offer stainless steel or zinc so you must be careful in your selections. Of course, the information on parts and sources is current when this web page is published in August 2014 but might not be later.
