Sheet Metal Two Flanges with Vertical Member Clearance Width Design

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)
