Description
Bespoke security and fire-rated steel doorset solutions built to the exact specification, within budget, any size, any colour, any ironmongery.
Manufactured from two 1.5 mm galvanized steel skins, folded and mechanically fixed to form a strong and rigid 45 mm 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.
90 mm frames are pressed from 2 mm galvanized steel to form a single rebated profile. Profiled headers form a smooth butt joint with the vertical posts and are joined together utilizing strong M8 bolts to provide positive rigidity. The special fast fit frame is able to compensate for most irregularities in the opening with 8no threaded fixing adjusters per doorset. They permit a tolerance of up to 18 mm on each side of the door. Shims and packers are not necessary making an extremely secure fix. Frames can be insulated if required.
Next Doors Ltd have a range of different threshold types to suit the end user requirements, from very low profile, to better weather sealed. Thresholds can also be swapped out with a square edge inside to ramp edge outside to suit floor level changes on site.
Door leaves are hung from 4no. stainless steel hinges for smooth operation and optimum weather resistance. Security dog bolts secure the leaf into the frame if the hinges are attacked. Additional hardware includes a range of locks, latches, lever handles, panic hardware, closers and stays. On double doors, lever-action flush bolts can be installed within the leading edge of the inactive door leaf. For extreme environments there is an option of galvanizing and marine grade powder coating for added durability.
