- Surface Roughness (Ra) 0.8 to 3.2 μm
- Max peak to valley height (Rmax) 4 to 30 μm
- Flatness 0.1 mm @ 400 mm


Minimum overlapping flange width:
- Overall – 5 mm
- Around bolts – 2mm


- The maximum gap at surface imperfections must be within 0.1 to 0.25 mm. Blowout resistance decreases with increasing gaps.
