Channel steel is widely used in construction projects. In building structures, it can be used as purlins on roofs, providing support for roof panels. It is also used in the construction of steel - framed buildings as part of the structural framework, helping to bear vertical and horizontal loads. In bridge construction, channel steel can be used for bridge decking support, railing structures, and some auxiliary components. Additionally, in industrial plants, it is often used to make equipment foundations, workbench frames, and pipeline supports.
