Steel Channels are "C"-shaped hot-rolled carbon steel sections featuring a vertical web and rounded corners on the top and bottom flanges. Steel channels are utilized for their structural strength in constructing building frames, braces, and supports for various machines and heavy equipment. In the construction industry, they are employed to reduce sound by placing them between the two sides of plasterboard walls. The channels help attenuate sound waves by dampening vibrations caused by sound on either side of the wall.
