1. Theoretical section properties have been calculated per AISI 2001. “Specifications for the Design of Cold-formed Steel Structural Mem-
bers.” Ixx and Sxx are effective section properties for deflection and bending.
2. Allowable load is calculated in accordance with AISI 2001 specifications considering bending, shear, combined bending and sheer and
deflection. Allowable load considers the worst case of 3 and 4 equal span conditions. Allowable load does not address web crippling,
fasteners/support connection, or uplift testing. 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 in uplift.

GENERAL INFORMATION
The minimum recommended slope for Delta Rib roofing
panel is 3:12. Metal Sales recommends that in all roof appli-
cations, sealants and stitch screws be used on all sidelaps.
Delta Rib is designed to be utilized over open structural
framing, but can easily be used with a solid substrate.
To avoid panel distortion, use a properly aligned and
uniform substructure.
Delta Rib panels are available in a
13
/
16
" rib height with a
coverage width of 24".
Minimum factory cut length is 5'-0". Maximum recom-
mended panel length is 40'-0". Longer panels require addi-
tional consideration in packaging, shipping, and erection.
Please consult Metal Sales for recommendations.
The fastener selection guide should be consulted for choos-
ing 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 installed fasteners. Over-driven fasteners will
cause stress and induce oil canning across the face of the
panel at or near the point of attachment.
