Equivalent for # 4 polishing
(OP)
Gentlemen,
Can anybody give me an ISO, EN or DIN surface roughness equivalent for #4 polishing or just the corresponding micron value?
Thanks in advance for your help!

My question was related to dairy/food purposes, not architectural.

Special finishes 1G (hot rolled) or 2G (cold rolled)
Type of process route: Ground
Notes: Grade of grit or surface finish can be specified. Unidirectional texture, not very reflective.
RE: Equivalent for # 4 polishing
Special finishes 1J (hot rolled) or 2J (cold rolled)
Type of process route: Brushed or dull polished (one surface only unless otherwise agreed upon at the time of ordering).
Surface finish: Smoother than ground.
Notes: Grade of brush or polishing belt or surface roughness can be specified. Unidirectional texture, not very reflective.

Thanks for pulling up that cross reference chart. I didn't realize #4 finish had such a wide range meanings, all the way up to 60 Ra (microinch).
Proof yet again advice here is only worth what you pay for it.
