Pre Galvanized Square Rectangular Steel Pipe
Square tube is a hollow, elongated pipe with a square or rectangular cross-section, hence its name. It is usually made of materials such as metal (such as steel, aluminum) or plastic. Generally, steel strips or plates are unpacked, flattened, coiled, and welded into circular tubes, which are then rolled into square tubes and cut into the required length.
