Prido sectional overhead doors are available in seven track systems adapted for space and application: T240 (low lift), T340 (standard low lift), T400 (high lift), T400 hF (high lift with lowered spring assembly), T450 (standard lift), T500 (vertical lift), and T500 hF (vertical lift with lowered spring assembly). Maximum width is 6,500 mm for T240 [...]

Yes, sectional overhead doors can be equipped with fully glazed sections made of natural anodized aluminum profiles with double-glazed insulating plastic windows. ISO sectional doors can also be fitted with plexiglass windows for increased natural light. Standard windows are elongated with straight or rounded corners, with single or insulating double glazing.

The U-value of a 5x5 m sectional overhead door from Prido varies with the section type: ISO 40 mm has a U-value of 1.02 W/m²K, ISO 60 mm has 0.77 W/m²K, and ISO 80 mm achieves an impressive 0.49 W/m²K. The ALU 40 mm fully glazed section has a U-value of 3.87 W/m²K. Therefore, ISO [...]

A sectional overhead door (also known as a sectional door) is an industrial door whose door panel consists of multiple sections that follow a rail system up towards the ceiling when the door opens. This means the door does not occupy any space outside or inside the premises when in the open position. Prido sectional [...]

Prido sectional overhead doors undergo durability testing, where prototypes are opened and closed 30,000 times and subsequently evaluated by experts. The torsion springs are designed for 30,000 operating cycles. The doors are CE-marked according to EN13241-1 and TÜV Nord-certified.

For maximum insulation, Prido’s overhead sectional door with ISO 80 mm sections is recommended, with a U-value of 0.49 W/m²K for a 5×5 m opening. This is approximately 85% better than a fully glazed ALU 40 mm section (3.87 W/m²K). ISO 80 mm is particularly suitable for heated premises where energy costs are important and [...]

Prido overhead sectional doors feature integrated cable break protection, spring break protection, slack cable protection on motorized doors, derailment-proof and finger-safe tracks, finger-safe section joints (on doors under 2.5 m), optical safety edges on motorized doors, and overload protection to prevent being lifted by the door.

A standard motor from GFA operates at 24 rpm, which corresponds to an opening speed of 0.15–0.25 m/s. Frequency-controlled motors can run at 65 rpm during opening and 30 rpm during closing down to a 2.5-meter opening. Frequency-controlled motors are ideal for areas with fast forklift traffic.

An overhead sectional door from Prido requires at least 250 mm of free side clearance on the motor side from the door opening. Other dimensions follow the standard for the overhead sectional door's track system. Compared to folding doors, overhead sectional doors require greater headroom because the door sections are stored under the ceiling.

A folding door folds sideways and requires minimal overhead and side clearance, while an overhead sectional door slides up under the ceiling and requires greater headroom. The folding door is more reliable and has lower maintenance costs, while the overhead sectional door opens faster and saves side clearance. Folding doors are often chosen for low-frequency [...]
