STT High Speed All Clear Roll Door

Advantages which are clear

At all passageways in company which are passed through from two directions, the clear view through the door offers decisive advantages: Accidents are prevented and smooth transport operations are guaranteed.

The door leaf of the EFA-STT® is kept in a certain distance in the spiral. Thanks to contact-less winding-up, the transparent laths offer a good view through the door for many years – and with hardly any wear. Therefore, the whole door convinces with a perfect look, even under hard everyday working conditions.

Door leaf guidance in perfection

The door leaf is not wound up on a shaft with “panel on panel” like a standard roller door, but kept space saving in a certain distance in the patented EFAFLEX spiral. This functional principle guarantees you quite a number of unique advantages: only this unique design combines highest opening speed, long service life, quiet action and efficiency in such a perfect manner. Thanks to the spiral, the doors move quietly and wear-free – and look as good as new for many years.

A bright view in air locks

In air locks, as they are used e.g. in the automobile industry, the transparent laths of the EFA-STT® bring much light into your workshop. They do not only provide a clear view but also have a perfect look and create a free atmosphere with open visual axes between the individual rooms. This makes work much more comfortable.

For universal use

The EFA-STT® can be used universally all all types of applications. Due to its product characteristics such as the modern and transparent design, the high opening speed and its sizes of up to 8,000mm x 7,800mm, it can be used for many different scenarios including warehouses, production facilities, carparks, carwashes, loading docks to name a few.


The EFA-STT® transparent laths provide a clear view to the other side for years. The door blade is held apart in the spiral, giving frictionless retraction, and so the high-speed door is extremely fast and the laths remain unscratched. Your premises become brighter, you save electricity and you have a clear view for safety. Furthermore, the EFA-STT® ensures constantly gleaming appearances even under hard working conditions.
