RESIDENTIAL DESIGN GUIDE
1. Theoretical section properties have been calculated per AISI 2007 'North American Specification for the Design of Cold-
Formed Steel Structural Members'. Ixx and Sxx are effective section properties for deflection and bending.
2. Allowable loads are calculated in accordance with AISI 2007 specifications considering bending, shear, combined bending
and shear, deflection and ASTM E 1592 uplift testing for 24 ga and 22 ga and UL 580 uplift testing for 26 ga. Allowable
loads consider the 3 or more equal spans condition. Allowable loads do not address web crippling, fasteners or support
material. Panel weight is not considered.
3. Deflection consideration is limited by a maximum deflection ratio of L/180 of span.
4. Allowable loads do not include a 1/3 stress increase for wind.

GENERAL INFORMATION
The minimum recommended slope for the Vertical Seam
roof panel is 3:12 over open framing and 1:12 over solid
substrate.
Clip spacing is based upon the spacing of structural
framing members and loading requirements.
Vertical Seam panels are available in a 1 3 /
4
" seam height
with a 12", 16", or 18" width coverage.
Minimum factory cut length is 5'-0". Maximum
recommended panel length is 45'-0". Longer panels
require additional consideration in packaging,
shipping, and erection. Please consult Metal Sales for
recommendations.
The fastener selection guide should be consulted for
choosing the proper fastener for specific applications.
Quantity and type of fastener must meet necessary
loading and code requirements.
NOTE: All panels are subject to surface distortion due to
improperly applied fasteners. Overdriven fasteners will
cause stress and induce oil canning across the face of
the panel at or near the point of attachment.
Finishes: in PVDF (Kynar 500 ® ), MS Colorfast45 ® , and
Acrylic Coated Galvalume ® .
