How Do Lally Columns Work?

Lally columns work by providing crucial support to the structure of buildings during the Lally column installation process. These columns, made of materials such as steel or concrete, are strategically placed beneath load-bearing beams or other structural elements. The adjustable nature of some lally columns, coupled with precise installation techniques, allows professionals in Queens, Long Island, and Brooklyn to fine-tune the height and provide essential structural support.

During the installation of lally columns, professionals use techniques like welding or securing them to concrete footings to create a robust support system.
