The application and detail drawings in this manual are strictly for illustration purposes and may not be applicable to
all building designs or product installations. All projects should conform to applicable building codes for that particular
area. It is recommended to follow all building regulations and standard industry practices.
Metal Sales Manufacturing Corporation is not responsible for the performance of the roof system if it is not installed
in accordance with the suggested instructions referenced in this manual. If there is a conict between this manual
and the actual erection drawings, the erection drawings are to take precedence.
Prior to ordering and installing materials, all dimensions should be veried by eld measurements.
Metal Sales reserves the right to modify, without notice, any details, recommendations or suggestions. Any questions
you may have regarding proper installation of these Residential roong systems should be directed to your local
Metal Sales representative, (see pages 2 and 3).
Oil canning is not a cause for rejection. Oil canning can be described as the amount of waviness found in the at
areas of metal panels. Oil canning is an inherent characteristic of light gauge cold formed metal products, particularly
those with broad at areas. There are many factors which may contribute to oil canning that Metal Sales is not able
to control. These factors include: misalignment of the support system, over driving of fasteners used on the panels,
stress (whether inherent in the panel or induced), thermal expansion and contraction of the panel, improper material
handling, width, gauge, length, color of panels, and improper installation (reference Metal Construction Association
"Oil Canning Position Paper"- Appendix A).
Consult your local Metal Sales Branch for any additional information not outlined in this manual.
Important Information
This manual is designed to be utilized as a guide when installing a Residential roong system. It is the responsibility
of the erector to ensure the safe installation of this product system.
SAFETY
STUDY APPLICABLE OSHA AND OTHER SAFETY REQUIREMENTS BEFORE
FOLLOWING THESE INSTRUCTIONS.
The installation of metal roof systems is a dangerous procedure and should be supervised by
trained knowledgeable erectors. USE EXTREME CARE WHILE INSTALLING ROOF PANELS.
It is not possible for Metal Sales to be aware of all the possible job site situations that could
cause an unsafe condition to exist. The erector of the roof system is responsible for reading
these instructions and determining the safest way to install the roof system.
These instructions are provided only as a guide to show a knowledgeable, trained erector
the correct relationship of parts to one another. If following any of the installation steps would
endanger a worker, the erector should stop work and decide upon a corrective action.
Provide required safety railing, netting, or safety lines for crew members working on
the roof.
Do not use the roof panel as a walking platform. The roof panels will not withstand the weight of
a person standing at the edge of the panel.
Do not stand on any roof panels until the panels have been attached.
The minimum recommended slope for the Vertical Seam
roof panel is 3:12 over open framing and 1:12 over solid
substrate.
Clips
Clip spacing is based upon the spacing of structural
framing members and loading requirements.
Coverage
Vertical Seam panels are available in a 13/4" seam height
with a 12", 16", or 18" width coverage.
Lengths
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.
Fasteners
The fastener selection guide should be consulted for
choosing the proper fastener for specic 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®.

1. Theoretical section properties have been calculated per AISI 2007 'North American Specication for the Design of ColdFormed Steel Structural Members'. Ixx and Sxx are effective section properties for deection and bending.
2. Allowable loads are calculated in accordance with AISI 2007 specications considering bending, shear, combined bending
and shear, deection 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. Deection consideration is limited by a maximum deection ratio of L/180 of span.
4. Allowable loads do not include a 1/3 stress increase for wind.
The minimum recommended slope for the Image II roof
panel is 3:12.
Substructure
Image II is designed to be utilized over a solid substrate.
To avoid panel distortion use a properly aligned and
uniform substructure.
NOTE: Image II roof panels are not recommended for use
over open structural framing.
Coverage
Image II panels are available in a 1" seam height with a 12"
or 16" width coverage.
Length
Minimum factory cut length is 5'-0". Maximum
recommended panel length is 30'-0". Longer panels require
additional consideration in packaging, shipping, and
erection. Please consult Metal Sales for recommendations.
