PANEL CLIP
The minimum recommended slope for the Magna-Loc
roof panel is 1/2:12.
Magna-Loc is designed to be utilized over open structural
framing or a solid substrate.
Clip spacing is based upon the spacing of structural
framing members and loading requirements.
Magna-Loc panels are available in a 2" seam height with
a 16" or 18" width coverage.
Minimum factory cut length is 5'-0" (with striations), 7'-0"
(without striations). 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: Acrylic Coated Galvalume ® and
PVDF (Kynar 500).
Gauges: 24 ga standard, 22 ga and 20 ga optional

1. Theoretical section properties have been calculated per AISI 2001 “Specification for the Design of Cold-formed Steel Structural Members.” 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 shear, deflection, and ASTM 1592
testing for 24 ga and 22 ga. Allowable load considers the worst case of 3 and 4 equal span conditions. Allowable load does not address web crippling or
fasteners/support connection or testing for 20 ga and 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.
