U Channel

starstarstarstarstar Steel U-channels, resembling the letter 'U', consist of a horizontal base known as the web and two vertical sides called flanges. Widely used in construction for their optimal shape, U-channels vary in production methods and final forms. The Iranian National Standards Organization only specifies standards for hot-rolled U-channels, but European and Russian standards also provide valuable information. U-channels are typically categorized into two production processes.
Hot-Rolled U-channels: These are formed when heated raw billets pass through rollers, shaping them into U-channels. The size of the rollers determines the size of the U-channels, often referred to as factory-standard U-channels.
