A C-Channel is a type of structural steel beam that has a cross-section shaped like the letter "C." It is commonly used in construction and manufacturing due to its strength and versatility. C-Channels are often employed in building frames, supports, and various applications where a lightweight yet sturdy material is needed. These channels are available in various sizes and thicknesses, making them suitable for different projects. They can be easily welded or bolted to other materials, such as steel plates or angles, allowing for flexible design options in structures like bridges and industrial buildings.
