Standard steel surface preparation level?

[StructureMan44]

For structural steel that will be painted and will be located on land near an ocean (salt in air) what is typically the surface preparation level SSPC-SP1 through SSPC-SP11 as found in AISC 325-10 table 2-8?

I think it really depends on the particular coating you are specifying. Acrylics, epoxies, etc. bond differently. Some can bridge over surface impurities, some not so much. I would say, select your coating and look in the manufacturer's specs - worst cast, give them a call.
