Corbels in steel structures are very common. For example, in heavy-duty industrial plants with steel structures, if crane beams are needed, corbels will be installed on the columns to support the crane beams, just like in concrete factory buildings. Corbel columns have the same function.

In addition to their application in steel structure factories, corbels are found in many building structures. In ancient buildings, the scientific name of corbels is "support arch". The leg is another name for a beam support. It is a support under the beam in a hybrid structure. Its function is to spread the force of the beam support to the load-bearing object below.

The corbels in steel structure factories are usually used to support rail crane beams. They are often found on the rows of single-story factory buildings. Their shape is a protruding inverted trapezoid, with a plane above and a flat below. Bevel edge, the height of the corbels in steel structure factory buildings is usually less than half the beam height. Corbels are not only used in steel structure projects, but also in concrete projects such as highways, water conservancy, and housing construction.
