Fireproof doors EI30-EI90

Glazed (glazing up to 90%) and unglazed fireproof doors are made of steel profiles produced by Voestalpine Austrian corporate group. The fire resistance of the doors is up to 90 EI.

• It is the narrowest system of fireproof profiles among their analogs (60 × 50 mm).
• It is the strongest system of profiles among their analogs (wall t is equal to 2 mm).
• This system of fireproof profiles is the most resistant to corrosion among their analogs (both outside and inside of the profile zinc layer thickness is 120 µm).
• The system has the lowest weight in comparison with analogs (a unique patented profile design).
• 2 mm profile wall thickness provides an increased structural-load capacity:
  • There is a possibility to make single leaf doors with a width of up to 1.5 m and with a height of up to 3 m, as well as two-leaf doors with a width of up to 3 m and with a height of up to 3 m;;
  • Glasses of maximum sizes can be used;
  • Strong threaded joints (for fittings fixation).
• They comply with the best modern practice with regard to smoke-proof doors and uninterrupted duty (Class C5 conforming to EN – 200 000 opening cycles).
• Applying any paint for metal, as well as powder paint, by RAL color palette.
• Both design and production of the profile are certified (which includes EN, ISO).
