Which code does this activity belong in?
The boundary between pipe and tube manufacturing and steel rolling and drawing lies in the final product form. Establishments that manufacture welded, riveted, or seamless pipe and tube from purchased steel are classified in this code, regardless of whether they perform additional finishing operations. Rolling and drawing operations that produce plate, sheet, strip, rod, and bar from purchased steel are instead classified in Rolling and Drawing of Purchased Steel, even when those products might subsequently be formed into other shapes.
