- Weather-stripping: the weather-stripping, made of EPDM rubber, is capable of resisting harsh conditions. The door panels have 8-fold male-female weather-stripping between all adjacent panels, and the door bottom has a double door-sweep.
- Hinges: elevating steel hinges with ball bearings
- Windows: Double pane selective thermal glass. Any windows mounted less than 28” above the ground are of tempered glass.
- Doors mounted to structure with mounting devices that are corrosion-proof to classification C4 [which, according to ISO 9223 keeps hinges rust free for 20-40 yrs.]
- Opening mechanisms:
- Manually opened doors: the door has a handle on its inside surface that allows its opening or closing.
- Machine opening: a motor or draw-chain device is mounted to a door panel.
- Additional specification: Fire resistance classification of EI30
- Maximum size 16.5’ x 16.5’
- Windows are not available on the doors with fire resistance classifications.
- The appearance is the same as a normal folding door.
- The fire resistant doors are heavier, therefore the mounting surface on the header face must always be at least 8” wide.
- The available opening machinery consists of a regulations consistent draw-chain using device.
Maximum size: 300” x 240”
- Structure: folding door having glass panels inside aluminum frames
- Thickness: aluminum frame thickness is 2”
- Weather-stripping: the weather-stripping is of harsh conditions bearing EPDM rubber. The panels have 2-fold weather-stripping between them, and there is a double door-sweep weather strip at the bottom of the door.
- Hinges: elevating steel hinges with ball bearings
- Windows: double pane selective thermal glass. Also available with triple pane glass. The windows less than 28” above the ground are of tempered glass.
- Kickguard of rust proof steel
- Opening mechanisms:
- Manually opened doors: the door has a handle on its inside surface that allows its opening or closing.
- Machine opening: a motor or draw-chain device is mounted to a door panel.
Suitable for the smaller and mid-sized folding doors with max. 3 or 4 leaves (smaller than 16,5′ x 16,5′), as at shops, smaller fire stations and barns.
- Motor: 24V motor operates with single phase electric current
- Safety equipment:
- An electric eye system in line with the door prevents the closing of the door if there is some physical object between the detectors.
- The door opening machinery includes a motor overload activated shut-off switch, which overload would be caused, for example, by a physical object preventing the opening or closing of the door. This prevents a breakdown of the machinery itself.
- Folding doors that include a built-in entry door have a disconnecting switch that prevents the opening of the folding door when the entry door through it is open.
- Three push-button switches, Open-Stop-Close, beside the door opening.
- The door is also operable manually during power outages.
- Control devices for the door opening machinery:
- Push-button switch box (Open – Stop – Close) mounted on wall
- Remote control switch
- The door opening machinery can be hooked up to the building’s physical access system
- Additional available features:
- Canceling electric eyes (the door automatically closes once a vehicle has crossed the beam of light to the electric eye)
- Radar utilizing door opening systems
- Control through VIRVE signals
- Magnetic loop door opener (installed in customer prepared conduit grooves)
Suitable for big doors (bigger than 16,5′ x 16,5′) that have 4 to 6 leaves and are opened very frequently, such as, for example, at fire stations, carwashes and factories.
- A separate rail for mounting the door opening machinery will be mounted above the door. The machinery will then be installed upon this rail.
- This machinery will be operated with normal grid electric current (3-phase current)
- Safety equipment:
- An electric eye system in line with the door prevents the closing of the door if there is some physical object between the detectors.
- The door edges that close against the building structure contain sensors.
- Folding doors that include an entry door have a disconnecting switch which prevents the opening of the folding door when the entry door through it is open.
- Three push-button switch box, Open-Stop-Close, beside the door opening.
- The door is also operable manually during power outages.
- Control devices for the door opening machinery:
- Push-button switches (Open – Stop – Close) in switch box.
- Remote control switch
- The door opening machinery can be hooked up to the building’s physical access system
- Additional available features:
- Canceling electric eyes (the door automatically closes once a vehicle has crossed the beam of light to the electric eye)
- Radar utilizing door opening systems
- Control through VIRVE signals
- Magnetic loop door opener (installed in customer prepared conduit grooves)
The opening for an entry door has a maximum width of 56″. The opening for the double door has a maximum width of 106”. If a wider opening is needed, then a folding door will be installed.
- Door cladding is of heat galvanized sheet steel, painted by heat cured powder coating.
- The door core is of insulating material that will not absorb water
- The door is pre-hung inside a frame of galvanized steel.
- The door assembly includes either a steel threshold or a double door-sweep on the bottom of the door.
