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 or
fasteners/support connection 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.

The minimum recommended slope for any Classic Rib roofing panel is 3:12.
Classic Rib is designed to be utilized over open structural framing, but can easily be used with a solid substrate.
The recommended substrate is 5/8" plywood with a 30 pound felt moisture barrier. To avoid panel distortion, use
a properly aligned and uniform substructure.
IClassic Rib panels are available in a 36" width with a 3/4" rib height.
i
Lengths under 5'-0" are available with some cutting restrictions. Maximum recommended panel length is 45'-011
Longer panels require additional consideration in packaging, shipping, and erection. Please consult your Metal
Sales branch for recommendations (see PGI-2 and PGI-3 for locations).
IClassic Rib panels are available in 29, 26, and 24 gauge optional. Minimum quantity may apply.

Sxx are effective section properties for deflection and bending.
2. Tabulated loads are allowable loads calculated in accordance with good engineering practices and with AISI 1996 specifications for bending
stresses. Panel weight has not been subtracted from allowable gravity loads. Allowable load does not address web crippling requirement, or
fasteners/support connection.
3. Allowable loads are calculated in accordance with AISI 1996 specifications, and have been increased by 33'/3% for wind uplift. Contact

DESIGN I INSTALLATION CONSIDERATIONS
Recommended Tool Type - Use depth locating nose or adjustable clutch on screw gun to prevent overdrilling and strip out.
Do not use impact tools or runners.
Seating the washer - Apply sufficient torque to seat the washer - do not overdrive the fastener.
CORRECT
Sealing material slightly visible
at edge of metal washer.
Assembly is watertight.
TOO LOOSE
Sealing material is not visible;
not enough compressionto seal
property. TOOTIGHT
Metal

To
prevent wobbling - Make sure fastener head is completely engaged in the socket. If the head does not go all the way in the
socket - tap the magnet deeper into the socket to allow full head engagement. Metal chips will build up from drilling and should
be removed from time to time. Protect
drill point - Push only hard enough on the screw gun to engage clutch. This prevents excess friction and burn out of the drill
point. Correct pressure will allow screw to drill and tap without binding. Drilling
through sheet and insulation - Ease up on pressure when drilling through insulation to avoid striking the purlin or girt with
the point - apply more pressure after drill point contacts purlin or girt. Drilling
through purlin overlaps - Drilling through lapped purlins requires extra care. Excessive voids between purlins sometimes
damages drill points and two self -drillers might be necessary to complete the operation. It is sometimes advantageous to
predrill. Whether
over solid substrate or open structural framing, panel distortion may occur if not applied over properly aligned and uniform
substructure. The
installer should check the roof deck for squareness before installing Classic Rib panels. Several methods can be used to verify squareness
of the structure for proper installation of the panels. METHOD "
A" - One method for checking the roof for squareness is to measure diagonally across one slope of the roof from similar
points at the ridge and eave and obtain the same dimension. METHOD "
B" - The 3-4-5 triangle system may also be used. To use this system measure a point from the corner along the edge of
the roof at a module of three (3). Measure a point from the same corner along another edge at a module of four (4). Then by measuring
diagonally between the two points established, the dimension should be exactly a module of five (5) to have a square corner.
Multiple uses of this system may be required to determine building squareness. If the endwall cannot be made square, the roof
system cannot be installed as shown in these instructions. METHOD
