Yes, a shipping-container floor can be partially or fully replaced. The right repair depends on whether damage is limited to one floorboard or involves contamination, fasteners, bottom rails, cross-members or the gooseneck tunnel. Before removing panels, identify ownership and future transport use, inspect the understructure, define required floor loading and have the repair completed to the owner’s, engineer’s or recognized container-repair criteria.
