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

Yes, the sectional overhead doors can be fitted with fully-glazed sections of natural anodized aluminum profiles with 2-pane insulating plastic windows. ISO sectional doors can also be equipped with plexiglass windows for increased natural light. Standard windows are oblong with straight or rounded corners, with single or insulating double-glazing.

The U-value of a 5×5 m Prido sectional overhead door varies by 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 has as low as 0.49 W/m²K. The ALU 40 mm fully glazed section has a U-value of 3.87 W/m²K. ISO 80 mm [...]

A sectional overhead door (also called a sectional door) is an industrial door where the door leaf consists of several sections that follow a rail system up toward the ceiling when the door opens. The door thus occupies no space outside or inside the premises in the open position. Prido sectional overhead doors are supplied [...]

Prido sectional overhead doors are durability-tested by opening and closing prototypes 30,000 times and then evaluated by experts. The torsion springs are dimensioned for 30,000 opening cycles. The doors are CE-marked to EN13241-1 and TÜV Nord-certified.

For maximum insulation, the Prido sectional overhead door with ISO 80 mm sections is recommended, which has 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 cost is [...]

Prido's sectional overhead doors feature built-in wire breakage protection, spring break devices, slack wire protection on motorized doors, derailment-proof and finger-safe rails, finger-safe sectional joints (on doors under 2.5 m), optical anti-crushing protective strip on motorized doors, and overload protection to prevent personnel from being lifted with the door.

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

A sectional overhead door from Prido requires a minimum of 250 mm free side space on the motor side from the door opening. Other dimensions follow the standard for the sectional overhead door's rail system. Compared to folding doors, sectional overhead doors require greater overhead height because the door leaves are stored under the ceiling.

A folding door folds sideways and requires minimal overhead height and side space, while a sectional overhead door slides up under the ceiling and requires greater overhead height. The folding door is more reliable in operation and has lower maintenance costs, while the sectional overhead door opens faster and saves side space. A folding door [...]
