The Framing is fabricated by welding and smoothing treatment of pre-galvanized tube-shaped steel profiles, filled with a gypsum based insulated material that restrict the transfer of heat energy, of series MCM-FIRE. The fabrication takes place in an MCM authorized workshop according to ISO: 9001 standard. The profiles are produced by steel strips (type: S250GDZ150NA), hot-dip galvanized with 150gr/m2 zinc overlay on both sides according to EN 10147 and cold roll formed according to DIN 2395 part 1&2. The wall thickness of the profiles is 2mm and the sectional dimensions are 60x50mm with an astragal of 20mm. Special grooves in the profiles are used to accommodate the fire resistant rubber gaskets or the ceramic tapes between the door frame and leaves. The frames are powder coated electro-statically to any standard colour of the RAL chart.
The Glazing is of special compound type with interlayer (24-32mm). Glazing rubber gaskets or ceramic tapes and clip-in beads (15-25mm deep) are used according to the glass thickness.
Optionally part of the glazing area may be replaced with steel panels of sandwich composition (steel plate 1,5mm + gypsum plate 12,5mm + steel plate 1,5mm).
The standard equipment of doorsets per door leaf includes two steel adjustable hinges of heavy duty type and a safety bolt in between. The doorsets are fitted with mortise locks combined with or without anti-panic function operable by push bars or lever handles. Door closers may be either overhead mounted or floor springs. Double leaf doorsets include sequence control selectors. Optional hold-open devices are available as separate magnet units or integrated in the closing mechanisms.
Installation is achieved by trained working teams ensuring the correct implementation of the specification standards and the validity of the certification. It is advisable that the neighbouring construction includes steel tubes at least 60mm deep where the framing of the MCM-FORM construction is fixed with screws. A thermal expansion gap of 10mm is allowed between the external framing and the neighboring constructions, that is filled with fire resistant mastic in white or grey colour.
CERTIFICATION OF MCM-FIRE CONSTRUCTIONS
The fire rating of MCM-FIRE constructions has been tested and certified according to the following Austrian Standards of fire safety and smoke protection ONORM 3800/3855 for the classification EI30 and EI60 (screens/doorsets).
