Cold Rolled SS Pipe Applications
Why Non-polished finish Stainless Steel Pipes are used?
You can save on Mill Finish pipes if there is no requirement of additional requirement of finishing such as 2B Finish, Mirror Finish, or BA Finish. These SS Pipes are used where visual appealing is not mandatory like in Automotive, Shipping, and construction sectors.
Many Stainless Steel Pipe Manufacturers supply the material in Non-Polished finish. In such case buyers need to spend additional for bright or mirror surface finish. At Kamal Steels, you can buy Mill Finish or Bright Drawn stainless steel pipe at very nominal cost.
