<br /> Slopes of less than 3"on 12"are not recommended. For slopes of 3"on 12"or greater,end lap panels 6". Side laps should face
<br /> away from the prevailing wind. Lay the first sheet along the eave at the down-wind side of the roof,farthest away from the
<br /> direction of the prevailing winds(See Figure#4). Install sheets in the sequence shown in Figure#4.

<br /> Allow an overhang a minimum of 1"at the eave to provide for a drip edge. Use inside closure at eave�to prevent water infiltra-
<br /> tion,insect or bird infestation at openings.To protect against uplifting winds and to provide a finishe�d appearance,apply rake
<br /> trim or other standard gable trim. For slopes less than 3:12,apply 3/8"tape sealant as shown in Figiare#6 along the top of all
<br /> lap ribs. Do not block the siphon channel with the tape. For best results,apply a 7/8"lap tek screw irito the crown of the rib to
<br /> secure the side lap.

<br /> NOTES:
<br /> 1.Theoretical allowable loads are based on section properties and allowables calculated in accordance with 2001 AISI Specifications.
<br /> 2.Theoretical allowable loads are based on three or more uniform spans.
<br /> 3.For roof panels,deduct self weight for actual'live load'capacity of the panel.
<br /> 4.These loads are for panel strength. Frames,purlins,decks and fasteners m�st be designed to resist all loads imposed on the panel.
<br /> 5.Check local building codes if panel testing is required.
