A figure in this table represents the weight per meter (kg/m) of the SUS304and SUS321.

  • A size whose weight is indicated is a standard size for manufacturing.
  • Please inquire about the length.

In addition to the above, we also provide piping rolls with the following outside diameters (the units are millimeters).
