We manufacture geodesic hub connectors for cold form steel geodesic design. This is a universal hub connection system that can be used ,make all sizes of domes. While it would work with wood lumber , we like cold formed steel and the system was designed to allow for geodesic construction with it.. Cold formed steel is insect proof and won't rot from moisture. It is inexpensive, easily available and exceptionally strong. It lends itself to geodesic design with our system


 I developed a uniform hub system for  3 frequency geodesic dome construction.  The hubs  are fabricated with CNC technology and made from  12 gage steel   This connector system is easy to use, but not cost effective for a pool covering, burning man, a back yard playhouse or causal greenhouse. There are several folks who weld steel connectors to create hub system for casual dome construction. I am happy to send you to a page with free designs for that kind of construction

Our geodesic connector systems has no welds that can fail. They are punched from plate steel with a $750,000.00 computer cad manufacturing process. These are not for creating childern's toys or seasonal buildings. These were designed for solid, long term construction in areas subject to sever weather. Each hub has two connectors and the cold formed steel framing members are utilized for maxium strength of the structure. The system was created so that people could work with steel lumber in their geodesic designs easily. They can be used for any size of dome.


The connectors sets are $1,800.00 plus shipping $55.00. daily). Every strut is bolted on the inside AND outside edges of the strut. There are three types of hub connectors and each vertice has two hubs,  You  bolt them into  pre  cut  and drilled steel struts.   This system is designed for cold form steel, not tubular steel. Tubular steel structures are difficult to cover, which one of the reasons we designed this system for Cold Formed Steel and optimized some the design for maxiumizing 4x8 plywood sheets.



   
We work locally and with natural resources, distilling certified organic witch hazel     We  harvest and distill certified organic wild foral essences . For this reason, I cannot manufacture the struts. We are open to working with a cold form steel manufacture in offering a full prefab kit. We also have a pine nut season, mid - September through Thanksgiving.  During these seasons, April through November, there is a two week lead time of shipping a hub system.fabrication.   Although,we do keep inventory on hand, we say two weeks to be on the safe side. Most of the time, people need to discuss their construction project prior to placing and order. There are times when, we are out in the field with our natural products business and organic farm. Durning these times, it is more difficult for me to answer questions on your project.

   The strut material for a 38ft 3v home are 12 and 16 gage 2x6 structural steel studs. We optimized strut length to work with 4x8 plywood sheets.
    Of course, the connectors could be used with wood,.
