Length: 4000mm; 8030mm; 8050mm; 12010mm; 12030mm; 12050mm; and so on. Max developed length: 30 meters, also U bending, finning, studded process can be provided.
Option: shot blasting on the outside surface to remove mill scale, make the surface matte colour; surface polishing as preparation work done for further processing, for instance finning. |
