Restoration of historic handrails is an important part of our work here in Capitol Hill. Stair and handrail components like the ones we restored in this project are some of the beautiful architectural characteristics that make Capitol Hill unique.
The steel railings on this project had been replaced since the original construction; however when they were replaced, the handrails were not properly welded or treated.
We reinstalled the handrails and welded them fully. In other photos (see below) you can see the up close views of the weld joints. The weld joints previously were not treated properly. The slag had note been removed after the weld bead cooled. Painting directly to slag does not work because the paint will not stick to slag. So over the years following the previous repair the joints had rusted through.
At the few locations where the joints had note rusted completely, the welds held but sheared off the cast iron post. We reattached everything and re-welded and treated the connections at the all the posts.
