• 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.
