They are: • Sa 1 Brush Off - Loose mill scale, loose rust and foreign particles are removed. • Sa 2 Commercial - Mill scale, rust and foreign particles are substantially removed and grey metal is visible. • Sa 2.5 Near White Metal - Mill scale, rust and foreign particles are removed to the extent that only traces remain in the form of spots or stripes. The cleaned surface will show varying shades of grey. • Sa 3.0 White Metal - Visible mill scale, rust and foreign particles are entirely removed. The cleaned surface should have a uniform metallic colour but may show varying shades of grey when viewed at different angles. • Sa 2.5 is common as a reasonably achievable standard for shipyards.
