What counts as a defect
UFGS 07 60 00 asks for finished sheet metal that forms a weathertight enclosure without waves, warps, buckles, fastening stresses or distortion.
At completion it asks for exposed metal surfaces free of dents, creases, waves and scratch marks.
On delivery the same specification looks for damage, dampness and wet-storage stains, so a defect can arrive with the metal.
