Show Solutions 3 meter (9.84 ft OD/7.94 ft ID), 4 sections

A 3-metre circle truss built from 290 mm x 290 mm conical straight truss, supplied as four arc sections that bolt together on site. Outer diameter is 9.84 ft and inner diameter is 7.94 ft. Conical connection means the sections join with coupler pins and conical end plugs rather than plated bolt patterns, which makes assembly faster and the joint stiffer. Circle truss like this hangs over a stage centre or a bar as a lighting ring, or defines a round position for a spinning fixture package. Splitting it into four sections keeps each piece truckable.
