1.6 DELIVERY, STORAGE, AND HANDLING
A. Protect steel deck from corrosion, deformation, and other

B. If ground storage is needed, store deck bundles off the
ground, with one end elevated to provide drainage.
Protect bundles against condensation with a ventilated
waterproof covering. Stack bundles so there is no danger
of tipping, sliding, rolling, shifting or material
damage. Check bundles periodically for tightness, and
retighten as necessary so wind cannot loosen sheets.
C. Place deck bundles on the building frame near a main
supporting beam at a column or wall. Do not place
bundles on unbolted frames or on unattached or unbridged
joists. Ensure that the structural frame is properly
braced to receive the bundles.
