Galvanized strip steel is a strip-shaped corrosion-resistant steel material that uses narrow steel strip as the base material and forms a uniform and dense zinc layer on its surface through continuous hot-dip galvanizing process. Its specifications are usually narrow (width generally less than 600mm), and it can be used directly as a finished product or often as a raw material for further processing. It combines the toughness of steel strip with the corrosion resistance of zinc layer, and has excellent cold bending and welding performance. Therefore, it is widely used as the basic raw material for spiral welded pipes, cold-formed steel, cable trays, and light steel joists in construction. Compared with traditional plates, it has a cost advantage in continuous production.
