We are getting our dome from geodesicbuildings.com
the dome weighs 240 kilos and is made of 30mm galvanized (weather & rust proof) steel
hub design
The hubs they use on all of the domes are designed primarily for strength and longevity.
Here you can see a close up of the design. The rounded shape of the flattened part of the pole is designed to spread the load evenly over the pole and hub, this gives their domes a tremendous increase in strength over a straight edged press design.
