Shape & Use: Square and rectangular hollow tubes. Frequently used in structural columns, welded steel frames, and modern architectural applications.
Manufacturing Process: Typically starts as a round ERW pipe. Once the round tube is welded, it is passed through a final set of shaping rollers that squeeze and flatten the sides to form the exact square or rectangular profile.
