  "textContent": "The method involves manufacturing a down pipe with a circular cross section by cold transformation and longitudinal weld from a high-fixed steel belt with an output structure. The down pipe is directly deformed in connection to the longitudinal weld during calibration process by the cold transformation to a hollow profile strand with a kidney-shaped cross section, where the hollow profile strand includes strength larger than 1.150 mega Pascal. The hollow profile strand is sectioned, where pre-section pieces of the hollow profile strand are provided at an end side with a mold section.",
