SWT has developed a support ring to aid in the assembly through minimization of the need for on-site welding.

The support ring is easily mountable on all of SWT's composite columns and consists of two halves, which are bolted together using two M16 bolts. The two supports are fastened in the ring, spread at a 90° angle using a M16 bolt per support.
The amount of support rings needed is usually limited, and once the casting is done on one floor they can be removed and used on the next.
