Uses and functions of Lally columns in modern construction

Adjustable Steel Columns or Lally Columns are thin-walled round telescopic tubes used in construction work as a temporary means of structural support. These implements can be adjusted in any direction. The inventor of the lally column was John Lally, an American innovator from Waltham, Massachusetts, who patented the invention and began production in the 19th century. Since then, Lally’s invention has become an indispensable part of the construction industry.

Construction crews can take advantage of the flexibility that columns provide. The height of the column can be adjusted according to current requirements. If a section needs to be cut to fit the dimensions of the room, the steel tube can be cut to size using common hand tools such as a reciprocating saw or pipe cutter.

The functions of the adjustable steel columns.

Lallies are available in a variety of lengths, from tubes just 12 inches long to columns 12 feet long. The main function of the adjustable steel columns is to support the weight suspended from above. They are oriented in a vertical direction and offer support to beams that extend a considerable distance. In modern construction, these telescopic tubes are very useful in preventing the collapse of the roof of a structure when supporting walls are removed during a renovation. Elimination of a load-bearing wall requires the use of a substitute structure, and adjustable steel tubes are built specifically for this function. With the steel tubes in place, the home or building remains structurally sound and safe for workers to do their jobs.

Due to the material used to make Lally columns, they are not designed for permanent use. To prevent buckling and improve the load-bearing capacity of the column, the casing is filled with concrete. As such, they become sturdy pillars that are fully capable of keeping the structure intact while the work is done. As soon as a supporting structure (eg, bracing, beam, load-bearing wall) that can support the weight above is completed, the columns can be removed.

What service providers offer

However, there is a growing concern about the durability of the lallies available on the market today. Over the years, changes have been made to the original design. For example, while years ago the thickness of the case was about a quarter of an inch, the models that are newer are only about 0.06 inches (16 GA). Compared to slats manufactured in the past, adjustable steel columns offer only half the strength. There is also growing concern about the risk of rust and corrosion associated with columns, as the main raw material used is steel. The risk is especially high when the abutments are used in humid and humid environments.

Many companies now manufacture custom columns, which are tailored to the requirements of the construction that is taking place. The services that construction companies now offer include designing, manufacturing, and shipping orders to clients. The most convenient way to purchase adjustable steel columns is to order them online directly from the manufacturers.
