Channel steel is a type of steel that is formed through rolling or cold bending, characterized by its channel-shaped cross-section. It is widely used in construction, manufacturing, and power industries.

Four shapes of channel steel, each with its specific applications. Cold-formed equal-leg channel steel features symmetrical cross-sections and uniform strength, suitable for light structures, power towers, and communication towers; cold-formed unequal-leg channel steel has an asymmetric cross-section, ideal for heavy structures and high-voltage power line towers; cold-formed inward-rolled edge channel steel has a smoother cross-section, suitable for steel structures and other buildings; cold-formed outward-rolled edge channel steel, with a more pointed cross-section, is used for steel structures, platforms, and bridges.
