Sweden’s best-selling folding door
Folding Doors for Industry and Garages
Some facilities demand a folding door of exceptional class. Facilities where design, function, and economy are equally crucial considerations. As the name suggests, Ecolid folding doors are a truly economical and environmentally strong alternative, offering a high-quality finish and minimal maintenance. So, if you need a well-insulated, affordable, and stylish folding door or hinged door, look no further.

Folding door
Why choose a folding door?
Prido’s sales strategy is to deliver high quality at the right price. Unlike many other door manufacturers, we are completely uninterested in the aftermarket. Our goal is not to sell service but to deliver quality right from the start. The door in our range that primarily lives up to our strategy is the manual folding door. Why is that?
A sustainable purchase
The folding door is engineered for longevity. The door is long-term tested for 1 million opening cycles. Correctly installed, it is virtually indestructible. Durability extends beyond mere lifespan. Our sandwich construction also provides a U-value that is approximately 40% better than frame-built folding doors.
Reliable
Electronics and automation are all well and good, but they do not last forever and can also be sensitive to external influences. A manual folding door practically never malfunctions. Prido sells 13,500 doors a year and has 50 years of industry experience. Believe us, we know the difference between different types of industrial doors.
Easy to open and close
A manual folding door is easy to open and close, even when the door is 7 meters wide and 6 meters high, thanks to a well-thought-out design.
Extremely low maintenance costs
When investing in an industrial door, one should be attentive to the cost of maintenance, i.e., what it costs to own the door. For some door types, the purchase itself is only a small part of the total cost. Many door manufacturers prescribe 6-12 month service intervals, and each individual service occasion can be costly.
We dare to claim that our manual folding door is practically maintenance-free. In normal industrial environments, no maintenance is required. In heavily polluting environments, washing may be required to maintain the rust protection. All care and maintenance can be handled without specialist expertise.
Reduced risk of collision damage
Folding door is synonymous with a significantly reduced risk of collision damage. The human field of vision is larger horizontally than vertically. Vertically, the field of vision can also be limited by, for example, the roof of a vehicle. The folding door’s side-moving motion means that the number of collision damages with crashed bottom sections and very expensive repairs almost disappears. If an accident should nevertheless occur, it is extremely easy to replace a folding door leaf. Unlike, for example, a sectional overhead door, a door technician is not required to carry out the replacement.
Simple and fast installation
The folding door is designed for simple and fast installation. A manual door can be installed by a handy person, even without specialist knowledge. But if you want help with the installation, Prido has well-trained installers throughout Sweden. Thanks to the simplicity, the installation cost is significantly lower than for other types of industrial doors.
Fits in most door openings
The folding door fits in most door openings because it requires minimal side space and overhead height and is available for both inward and outward opening.
