Using additional components

You can use additional system or custom components to modify the column end or the base plate. For example, you can create special backing plates, weld preparations, and weld access holes for the column end.

If you use additional system or custom components, you need to manage the column end or the base plate properties in the additional component in question. When using several components, there may be multiple welds and cuts.
