Yes, a shipping container can have full cargo doors at both ends. The lowest-risk route is usually to buy a purpose-built double-door or “tunnel” container, a configuration currently listed by Canadian suppliers, rather than assume a fabricator can duplicate a factory end on any used box. A retrofit may be possible, but it needs unit-specific structural design, fabrication details, weather sealing and a clear decision about whether the container will ever return to regulated transport service.
First decide whether this is a purchase or a retrofit
Map two operating aprons, not just one footprint
Factory labels and actual measurements beat assumptions
A field-added end requires engineering accountability
Transport status must be explicit
Two entrances double several maintenance points
Accept the exact configuration you ordered
Price two-end access with its documentation
Ask for exact unit photos and identification, both finished door openings, delivery orientation and transport status. If retrofit work is proposed, require the design, fabrication, sealing, coating and inspection scope.
