Is the 12 ft. Corrugated Galvanized Steel 29-Gauge Roof Panel strong enough to support the weight of a person?

The panel is not strong enough to support the weight of a person.

No, the 12 ft. Corrugated Galvanized Steel 29-Gauge Roof Panels are non-structural and would need substrate installed underneath to support the panels. Our recommended minimum substrates are 15/32 plywood or 7/16 OSB decking.
