T-30 Fire-resistant door

double-leaf, with steel door frame

This type of doors with fire resistance parameters from 30 to 90 min (Т30, Т60 and Т90) is used to prevent propagation of fire in buildings in order to save properties and protect human lives. For these purposes buildings are shared into fire-proof zones with defined escape routes. Doors of adjoining rooms must be designed so as to prevent the spread of flame.
