HINGE - Doors without bottom guide rails

The Bifold glazed door is made up of doors made of tubular steel perimeter profiles with "L" section dim.60x90mm. and connecting crosspieces made of tubular steel profiles with 'T' section dim.60x90mm. all with zinc bath finish and subsequent painting in a RAL colour of your choice with peel effect. Half glass curtain walling of the type and finish of your choice (double glazing, safety glass, transparent, satin glass, etc.) with a maximum total thickness of 40mm. Snap-in glass stop made with suitably sized profile in painted aluminium in the same colour as the door. The load-bearing structure is made up of side posts in galvanised tubular steel painted black and an upper guide, made to our design, in steel material with electrolytic galvanised finish and painted black.

This type of door does not require a lower guide because the two side posts and the upper guide are connected to each other and consequently walled in, thus forming a real frame for the door guaranteeing a high degree of stability and rigidity. One or more aluminium slippers are doweled to the floor so that the pin with the olive in galvanised steel can be inserted and the door can be closed. On the inside, at man height, there are wheelbarrows and handles in black painted aluminium alloy for opening and closing the door itself.

The wheelbarrows have 4 fixing points and central clutch. The sabre handle prevents the hands from being crushed and guarantees the sliding of the galvanised steel and black painted rods, with two locking points. They are fastened in slide-throughs, where Teflon supports are inserted to guarantee precision and remarkable sliding. The upper ends of the rods are made up of die-cast aluminium end caps that close the door in the upper rail. By gripping the ergonomic handles in die-cast aluminium, it is possible to move the door with extreme ease thanks also to the trolleys with nylon-Curtained bearings that slide in the upper guide (already prepared for any motorization).

The hinges, with frontal and internal fixing, are in aluminium alloy in matt black colour and obtained by die-casting process; a particular study has allowed to obtain hinges able to absorb shocks of means in order to limit possible damages to the doors. With the insertion of self-lubricating bushings and thrust bearings, maintenance is reduced to a minimum. Galvanized pin with anti-fall and milling system to ensure fixing with internal grain. This system prevents it from slipping off, with the consequent opening of the door.

The sealing gaskets between sash and door, with crossed double leaf, are in EPDM (anti-aging) natural rubber to guarantee maximum closure; moreover the space between the sashes is 50 mm (anti-crushing) on all versions: manual, motorised or motorised as per current regulations. In the upper and lower part the closure is guaranteed by a double needle gasket with pre-cut parts to guarantee the possibility of adjustment on non-planar floors. Finally, the vertical and horizontal gaskets are thermally welded together to create a single profile that guarantees tightness and thermal insulation.
