Our folding doors are lightweight and easy to use, even in large sizes, whether equipped with automated systems or manual operation.
We are here to assist you with any inquiries related to our products and services, as well as in the planning of projects and contracts. Our team of door experts and extensive network of collaborators are always ready to roll up their sleeves!
The table below determines the number of door leaves generally based on the width of the opening. We are also able to produce solutions that deviate from the table.

Features of our products
The durable and low-maintenance Findoor folding door is a great choice for various applications including barns, fire stations, airports, industrial buildings and service stations. Its surface is coated with steel sheeting and it features a water-resistant insulation. The lifting stainless steel hinges keep the bottom seal in good condition and make opening the door effortless. The EPDM-rubber seals withstand even extreme northern conditions. If needed, the folding door can also be equipped with an access door.
Steel clad folding door specifications
Maximum size: 600″ x 320″ (15000 × 8000 mm)
Structure: Thermally insulated, sandwich-structured folding doors
Cladding: Heat galvanized sheet steel, with a minimum thickness of gauge 26 (0,5 mm).
Insulation thickness: 2 3/8″ (60 mm)
Colour: From colour chart
Water resistance classification: 3 EN 12489 and EN 12425
Wind pressure classification: 4 (up to a height of 4 meters) EN 12444 and EN 12424
Air permeability classification: 4 (determined by door size) EN 12427 and EN 12426
Sealing: The door panels have 8-fold male-female sealing between all adjacent panels, and the door bottom has a double doors-sweep. The seals are made of EPDM-rubber, which can withstand harsh conditions.

Windows: Triple-pane thermal glass
Opening mechanisms:
- Manually operated: The door is equipped with an interior handle for opening and closing
- Opening machinery: Door mounted operator
Door mounted operator
Suitable for 2-, 3-, 4-, 6- and 8-panel doors. Operator is attached to the door panel, so it doesn’t take up space above the door. Excellent solution for smaller and medium-sized doors, for example in industrial buildings, 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)
- 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)
Entry and double door specifications
The opening for an entry door has a maximum width of 1395 mm.
The maximum width for a double door opening is 2655 mm. For wider openings, a folding door is recommended.
