Dear teachers: Does the exterior wall of a steel structure warehouse with a fire resistance rating of grade 2 need to be a fire wall? If it’s not a firewall, then it could be considered a non-load-bearing wall.
The exterior walls of a steel structure warehouse with a secondary fire resistance rating do not have to be firewalls; they can be non-load-bearing walls. .
