3. Manufacturing Process:

1).Directly into Square: make continuous angle deformation of cold-rolled or hot-rolled steel plate directly, and then by high frequency welding form a rectangular steel tube forming method. Also known as square-square method.

2). Round to square: make continuous angle deformation of cold-rolled or hot-rolled steel plate directly, and then by high frequency welding form a round steel tube forming method, though the reshaping finally form a rectangular steel tube forming method. Also known as round to square method.
