Lally columns are thin round-walled structural steel units which are used to offer support to timbers or beams stretching over long spans. In some cases, their steel shell is generally filled with concrete carrying compression load thus assisting to prevent the shell local from buckling.
Lally columns are very beneficial and come with the advantage of the ability to cut easily to the desired lengths all according to the requirements of the construction site with the use of simple tools for example pipe cutters or even a reciprocating saw. This is an extra advantage over conventional basement column. They are not that tough or sturdy when compared to their conventional counterparts.
Lally column were named after a U.S inventor, John Lally, who had a construction company. It is from this company the production of the columns began.
These columns are extremely popular today and are used extensively. This is probably because of the numerous advantages they have despite the little shortcomings and downfalls. The strengths they have to include the following-
Structural stability to make construction projects easier-
These columns offer the Structural stability that makes construction projects easier. They can be utilized in a number of places during construction to grant the needed stability of the structure; So that only high- quality construction is achieved at the end of the day.
These columns are cost effective –
The materials from which these columns are made are readily available and therefore easy to access. The use of concrete and steel which are easily accessible in the market makes the columns quite cost effective by nature
Lally columns are easily cut by simple cutting tools –
These columns offer an easy time cutting even with the use of small cutting tools. It consequently gives the builders an easy time getting the right sizes for diverse areas during construction. It is hence understood that they are a prevalent choice in the construction industry.
Due to the material used in making Lally column, they are not designed for everlasting usage. So as to prevent buckling and to develop the weight-bearing capability of the column, the concrete is used to fill the shell.
They convert into sturdy pillars that are completely capable of keeping the structure intact while work is being done. A lot of companies nowadays fabricate customized columns, which are designed to fit the requirements of the construction that is underway. As soon as supporting structures for instance bracing, beam, the weight-bearing wall is completed which can support the weight above, the Lilly columns may be removed.
