T30/T60/T90 classification for gates in Morsbach.
Fire-rated gates are building-authority-approved closures for warehouses. They hold back fire and smoke for 30, 60 or 90 minutes — kept open via hold-open devices in normal use, automatically closing on fire alarm, smoke detection or power loss. In Morsbach, this is the typical setup for any compartment-dividing gate in production or logistics.
