Surface Finish
Steel is first rolled to the wanted size and thickness and
then annealed to change the properties of the final material. Any
oxidation that forms on the surface is removed by pickling,
and a passivisaion layer is created on the surface. A final finish
can then be applied to achieve the desired aesthetic.
The surface of our round welded stainless steel heat exchanger
tube includes:
mirror polishing/stain/customized
