Industrial sectional overhead doors are basically divided into those operated manually or with help of a chain hoist. Doors can be equipped with an electric drive mechanism of various power and intensity parameters.
Industrial-grade overhead doors differ from residential garage doors by the following:
- Door surface dimensions, width up to 9 m, height up to 10 m.
- Wider range of door lift mechanisms allows installing the doors in rooms of almost any layout.
- Wider operational intensity range that is ensured by high-resistance parts and longer torsion spring life cycles. The minimum number of cycles is 25,000.
- Upon arrangement with the manufacturer, also heavier-duty superior life-cycle torsion springs are available.
Door standard package includes:
- Door panels in standard colours (white; brown; silver)
- Panels with protection against finger trapping between sections
- A convenient handle for opening and closing the door
- A bolt for locking the door from the inside
- 2 year warranty period
