C-channels, also known as C-beams or C-sections, are structural components shaped like the letter "C." They are commonly made from steel or aluminum and are used in construction and manufacturing for their strength and versatility. C-channels provide support and stability in various applications, including framing, shelving, and machinery. These channels are designed to bear loads and resist bending, making them ideal for structural frameworks. Their open shape allows for easy attachment to other materials, such as wood or sheet metal. C-channels are often used in building construction, automotive manufacturing, and furniture design due to their durability and efficiency.
