Mild steel U channels, also known as mild steel channels or mild steel C channels, are hot-rolled carbon “U” shaped steel with inside radius corners that are widely used in general fabrication, manufacturing and structural applications. The U-shape or C-shape configuration of a mild steel channel provides superior strength and structural support when the load of a project is horizontal or vertical. The shape of a mild steel U channel also makes it easy to cut, weld, form and machine.
