Sheet Metal Two Flanges with Vertical Member Clearance Width Design Equations and Calculator.
Flange Width (FM) = EM + EM2 + PT
or
Flange Width (FM) = SB + EMT + C / 2
Whichever is largest
Where:
FM = Flange Width (in, mm),
EMT = Edge Margin Tolerance: Typical (.05 in, 1.27 mm),
C = Fastener Head Diameter (in, mm),
PT = Edge to Bend Radius (in, mm),
SB = Setback Radius on Outside Wall (in, mm),
EM = Flange Edge to Fastener Center (in, mm)
EM2 = Flange Edge to Fastener Center (in, mm)
