The balancing of the sectional door is ensured by torsion springs in galvanized harmonic steel. The springs are fixed to the shaft via die-cast aluminum mandrels; the shaft is made of galvanized steel of adequate thickness, and has a hollow tubular section for housing the safety keys. The aluminum drums on which the steel ropes that lift the door are wound are fixed to the ends. The system is calculated for use of 25,000 cycles, i.e. 4 cycles per day for 10 years, but systems for intensive use up to 100,000 cycles can be supplied on request (only if technically feasible). The spring cover casing, when foreseen or requested, is made of white pre-painted steel.

The sliding guides are made with steel profiles of suitable thickness and section such as to contain the nylon wheels that support the panels. Vertically they are fixed on the angular profiles arranged for fixing on the masonry bundles or on the steel uprights; special co-extruded gaskets with soft lips, applied on the aforesaid corner profiles, guarantee air and water tightness with the panel. Special self-supporting corner plates, fixed to the upper end of the corner profiles, support the balancing spring unit and the external rib when required. The horizontal sliding section consists of a double guide profile of which the one positioned at the bottom has a curved end that abuts perfectly with the vertical guide to allow the continuity of sliding of the door. The second guide (positioned towards the ceiling) ends with a truncated curve in which only the wheel positioned on the upper part of the last panel is channeled with the aim of guaranteeing perfect closure of the mantle. The double guide is fixed to the masonry using pre-drilled corner brackets.

The mantle is made up of panels

80 MM PANEL

Ideal for refrigerated areas, it does not require pedestrian doors or hinge reinforcements.

Depending on the size of the doors and/or the color of the panels, omega-shaped reinforcing profiles made of galvanized steel or painted white Ral 9010 are applied from the inside side to counteract heat-induced buckling and wind resistance. Minimum wind resistance of Class 2.

The panels are connected to each other by hinges screwed into the inside of the panel.

On the lower edge of the first panel, the EPDM gasket for sealing to the floor is inserted with a “U” profile in powder-coated aluminium matching the colour of the roofing.

The door is always accompanied by a CE plate with reference serial number, installation, use – maintenance – safety manual and DOP declaration of performance in compliance with the regulation on building materials 305/2011 CPR and in compliance with the harmonized standard EN 13241-1.

ANTI-BURGLARY SECURITY

Genius is a sturdy door, well anchored in the sliding guides with solid supports at the ends of all panels. In addition to the locking system guaranteed by the motor, the door can be equipped with a latch and lock with knob (on request).

A plastic grip with the Ferraro brand is always applied to the door; to ensure the closing of the door, on request, a steel bolt can be applied internally (make sure that there is another access in the garage or the sectional door has inserted a pedestrian door) or a lock with cylinder and external knob. On request, doors that open with a side motor are fitted with an electric lock that is automatically activated when the door is closed.

In order not to cause damage to people and things, the sectional door can be equipped with safety devices that block movement of the door in the event of breakage of the lifting cables and torsion springs. Where required or if required, special nylon protections are applied to the sliding wheels to prevent fingers from being crushed during door operation.
