GI Steel Square Tube Machine is a series of machines that builds longitudinal weld seam tubes and pipes with steel strips of certain width.

• It starts by uncoil and flatten the slitted steel coils into steel strips.
• The flattened steel strips will then be inserted into the forming machine and the roller tolling in the machine will roll the strip to round pipe shape.
• The rolled strips will then be sent into the weld box where the tube is welded by a high frequency solid state welder.
• The welded tubes will be formed to expected shape or size in a sizing machine. Finally the tubes will be cut to length and bundled.
