Door Leaf
Manufactured from two 1.5mm galvanised steel skins, folded and mechanically fixed to form a strong and rigid 45mm thick door leaf, filled with internal steel strengtheners and mineral wool for ultimate insulation. Anti-jemmy flanges to the leading edge of the leaf provide excellent jemmy resistance.
Frame
90mm frames are pressed from 2mm galvanised steel to form a single rebated profile. Profiled headers form a smooth butt joint with the vertical posts and are joined together utilising strong M8 bolts to provide positive rigidity. The special fast-fit frame can compensate for most irregularities in the opening with eight threaded fixing adjusters per doorset, which permit a tolerance of up to 18mm on each side of the door. Shims and packers are not necessary making an extremely secure fix. Frames can be insulated if required.
Threshold
DDA-compliant 2mm stainless steel threshold bolted into the vertical frame posts. Available in outward opening, inward opening, and ramped.
Vision Panels and Glazing Systems
The active leaf in the fire test included two vision panels with the upper panel having overall dimensions of 203mm wide x 711mm high and the lower panel being 203mm wide x 508mm high. This test demonstrated that the inclusion of vision panels will not be detrimental to the fire performance of unlatched door leaves for a period of up to 240 minutes.
For doorsets that are required to have 120-minute fire resistance, the height of the vision panel can be increased by 15% and the maximum area to be increased by 20%. The maximum permitted vision panel dimensions are 818mm high or 416mm wide, subject to a maximum area of 0.17m².
Hardware
Door leaves are hung from four stainless steel hinges for smooth operation and optimum weather resistance. Security dog bolts secure the leaf into the frame if the hinges are attacked.
Finish
Available in any RAL colour or marine-grade powder-coat finishes.
