Who has standard photos of the Sa grade for rust removal? I hope it can be uploaded and shared; I’ve only had a textual understanding of it and have never seen the actual standard version. I hope some expert out there can help!

I have them, but I can’t upload photos and files. Those who need them can leave me their address and I’ll send them to you. Remember to give me points!

GB8923-88 specifies the rust grade and derusting grade of steel surfaces prior to painting. I’ve seen this standard before, but I don’t have it with me now. The original poster should look for it themselves.
