Product Overview
U channel is rolled in one piece with a slight taper on the inside of the legs, and web and leg thickness are matched to GB/T 706 so fabricators can drill, weld and cold bend it into arches without trouble. Compared with tube or H sections it is the cheapest steel per ton, and the open profile makes it easy to thread bolts and cables through – which is why it is the most used secondary member in steel buildings.
