|---|---|
| ≤ 3 | ±0.3 |
| 3 < t ≤ 5 | ±0.4 |
| 5 < t ≤ 8 | ±0.5 |
| 8 < t ≤ 15 | ±0.6 |
| 15 < t ≤ 25 | ±0.8 |
| 25 < t ≤ 40 | ±1.0 |
| 40 < t ≤ 80 | ±1.2 |
| 80 < t ≤ 100 | ±1.4 |
| 100 < t ≤ 150 | ±1.8 |
| 150 < t ≤ 200 | ±2.2 |
| 200 < t ≤ 250 | ±2.6 |
Gnee ensures the precision of S235J2 plates by complying with these tolerances, with options for special customizations based on project requirements.
