- The baseplate is made of a 12 inch square type 6061 T6 aluminum plate that is 3/16 inch thick.
This particular type aluminum is harder than pure aluminum and less likely to bend while being
resistant to weather. U-bolts attach the spreaders to the baseplate.
- Two square base floor flanges normally used for handrails are used to mount the center post to
the base plate. One is on the top for mounting the center post and the other is on the bottom for
insertion of the mast. These flanges are made of aluminum-magnesium alloy.
- Stainless steel hardwareshould be used to minimize corrosion especially in saltwater
environments. Lock washers should be used; otherwise movement of the hexbeam by wind and
rotation will eventually work the fixtures loose.
