Sa2.5 grade means that after abrasive blasting, the steel surface is virtually free of visible grease, dirt, mill scale, rust, and paint coatings, with any residual traces being only slight discolorations in the form of spots or streaks, and it is the minimum requirement for heavy-duty anti-corrosion engineering.
We can provide customized anti-corrosion paint formulations and coating systems based on your specific working conditions. If you have any selection questions, feel free to discuss them in the comments, or contact us directly for professional advice.
