Custom Colors are available on orders of 3,000 lft. or larger. Consult an AEP Span representative for additional information.
Configuration: [choose one]
Wide Batten: Roof panels shall consist of snap-on batten caps 1-7/8” wide and 1-7/8” high spaced (choose one) [17-1/4” or 22-1/2”] on center and a nominal panel width of the same. Panels shall be factory correctively leveled.
Narrow Batten: Roof panels shall consist of snap-on batten caps 3/8” wide and 1” high spaced (choose one) [16” or 21-1/4”] on center and a nominal panel width of the same. Panels shall be factory correctively leveled.

NOTE: Flat metal surfaces will display waviness commonly referred to as “oil canning”. This is caused by steel mill tolerances and is a characteristic, not a defect, of panels manufactured from light gauge metal. Panels are factory correctively-leveled to minimize the occurrence of “oil canning”. As such, “oil canning” will not be accepted as cause for rejection.

ACCESSORIES
Fastener Clip

Prior to starting work, notify General Contractor about defects requiring correction.
Do not start work until conditions are satisfactory.
PREPARATION
FIELD MEASUREMENTS
Verify prior to fabrication.
If field measurements differ from drawing dimensions, notify Architect/Engineer prior to fabrication.
PROTECTION
Treat, or isolate with protective material, and contacting surfaces of dissimilar materials to prevent electrolytic corrosion.
Require workmen who will be walking on Roofing panels to wear clean, soft-soled work shoes that will not pick up stones or other abrasive material which could cause damage or discoloration.
Protect Work of other Trades against damage and discoloration.
SURFACE PREPARATION
Clean and dry surfaces prior to applying sealant
INSTALLATION
PANELS
Follow roof panel manufacturer’s directions.
Install panel seams vertically.
Secure panels without warp or deflection.
Fully engage battens.
Remove strippable protective film, if used, immediately preceding panel installation.
ALLOWABLE ERECTION TOLERANCE
Maximum Alignment Variation: 1/4 inch in 40 feet.
FLASHING
Follow manufacturer’s directions and architect approved Shop Drawings.
Install flashings to allow for thermal movement.

CUTTING AND FITTING
Neat, square and true. Torch cutting is prohibited.
CLEAN UP AND CLOSE OUT
PANEL DAMAGE AND FINISH SCRATCHES
Do not apply touch-up paint to damaged paint areas that involve minor scratches.
Panels or flashings that have severe paint and/or substrate damage shall be replaced as directed by the Architect’s or Owner’s representative.
Note: AEP Span does not recommend touch-up painting of damaged surfaces (minor scratches, etc.) due to fading and weathering differences of the touch-up paints in comparison to factory applied paint systems.
CLEANING AND REPAIRING
At completion of each day’s work and at work completion, sweep Panels, Flashings and Gutters clean. Do not allow fasteners, cuttings, filings or scraps to accumulate.
Remove debris from Project Site upon work completion or sooner, if directed.
