What is a lally column?

A lally column is a widely used support column that is typically made of steel or concrete. It is cylindrical in shape and is often used to provide additional support in buildings and structures. It is also known as a support column, structural column, or a basement pole. The name "lally column" comes from its inventor, John Lally, who was a construction contractor in Massachusetts in the late 19th century. Lally columns are commonly used in homes, commercial buildings, and industrial facilities to provide structural support for ceilings, roofs, and other types of constructions. They are available in various sizes and can be customized to fit specific needs. Lally columns are popular because they are easy to install, cost-effective, and are resistant to fire and moisture.
