Strong
Robust for intensive use
The Strong is the solid, entry-level indoor high-speed door, built for larger openings up to 25 m² and intensive daily traffic. Aluminium reinforcement profiles with EndLocks keep the curtain taut in the guides, even with draughts and pressure differences.
- Max. area
- 25 m²
- Opening speed
- up to 1.8 m/s
- Wind class
- up to class 2
- Max. size
- 5,000 × 5,000 mm
Built to last
The curtain consists of horizontal sections of wear-resistant PVC, each with an aluminium reinforcement profile and integrated EndLocks. These profiles hook into the side frames so the curtain cannot be pushed out of the guides. A transparent vision panel is standard.
All parts are heavier than on the Prime. You notice it in a stable door run, a long service life and lasting draught protection and energy savings.
Four versions
Choose the Strong-E as an affordable version for smaller openings, the Strong-XF for maximum speed, or the Strong FullVision with a fully transparent curtain. See the differences below.
