Part3 Execution
3.01 Inspection

3.01.01 Check alignment of supports before placing panels. Bearing surfaces for panels must be clean.

3.01.02 After placing on supports, adjust panels to final position with proper bearing and alignment at joints, laps, and supports before fastening.

3.02 HANDLING AND STORAGE OF FRP ROOFING SIDING, AND LINER PANELS

3.02.01 Protect panel surfaces from cuts, scratches, gouges, abrasions, and impacts.

3.02.02 Store panels with one end elevated; do not store flat. Keep all FRP materials covered – do not stack or store other materials on top of panels. Store materials in a dry location, off the ground, and allow for ventilation.
