The Waldinger Corp. recreates pieces of history

DSCN2191When a century-old home in Blair, Nebraska, needed to restore their two crumbling rooftop cupolas, the construction company on the job brought them to The Waldinger Corporation located in Omaha to rebuild them. Known for their stellar reputation in custom metal fabrication, Waldinger’s fabrication specialists did an outstanding job of precisely recreating both cupolas.

DSCN2197The company’s specialists measured the dimensions of the original cupolas—one tall, thin, and elaborate, and the other square with a rounded top—then used the basic CAD/CAM process to entirely recreate both pieces.

Then, one of their talented craftsmen formed and soldered the elaborate pieces. The cupolas were fabricated from 24 gage galvanized steel, ASTM (American Society for Testing and Materials) A 653 CS Type B, and bar solder.

DSCN2196The CAD/CAM process allowed Waldinger’s custom fabricators to create the final products even more accurately than when both cupolas were originally created, more than 100 years ago.
