Members shall not be in contact with sides or ends of the car. Members placed longitudinal in cars shall be protected from damage due to accidental longitudinal shifting by installing between bundles and at ends of metal-end cars substantial wooden panels, firmly wired in place, or by covering ends of bundles with suitable padding of burlap or other soft material.
All shipping blocks, panels or end covers shall be adequately padded with burlap or other soft, durable material to prevent abrasion of the galvanized finish. All shipping tie downs shall be non-metallic.
Bolts complete with nuts assembled shall be shipped in kegs or boxes strong enough to withstand the necessary handling and strong enough to prevent damage in transit and with none weighing more than 300 pounds.

Connecting wires shall be strong enough to withstand the necessary handling and shall be galvanized.
Anchor bolts with ungalvanized portions shall not be stored or shipped on top of galvanized members to avoid rust staining galvanized surfaces.
In general, complete structures with bolts shall be included in each car. Where more than one structure is shipped in the same car, the material for different structures shall be segregated. Materials shall also be segregated by Bid Schedule.
Due precautions shall be taken when handling and loading tubular steel members to prevent damage to the shafts or their finishes.
