Details
Excellent dimensional stability
The door leaf is made of individual, replaceable segments of PVC-coated polyester fabric. Aluminium profiles reinforce segments at 225 mm spacing, providing stability for large openings and enabling individual segment replacement to reduce repair costs and downtime.

Perfect guide of door leaf
The spiral housing does not wind the curtain onto a shaft but retains it at a distance, saving space. This arrangement combines very high opening speeds with low wear, quiet operation and long service life.

Individual design options
Multiple curtain colours are available. Examples of RAL colours include:

• RAL 1021 Rapeseed yellow
• RAL 3000 Fire red
• RAL 5002 Ultramarine blue
• RAL 7035 Light grey
• Other colours available on request

High-end safety technology
Products meet stringent safety standards to protect personnel and goods. Options include EFA-SCAN® laser scanner and Active Crash System EFA-ACS® for controlled automatic reset after collisions.
