High-speed spiral door EFA-SST®.

The original.

The EFA-SST® high-speed spiral door represents a new generation of industrial doors: perfect insulation, energy-efficient functionality, state-of-the-art technology. During the technical redesign, particular attention was paid to improving the physical properties of the door leaf as well as optimising the functionality, thus once again raising the standard of EFAFLEX industrial doors.

EFA-SST® at a glance:

  • Max. heat insulation with EFA-THERM® laths
  • Opening up to 2.5 m/s
  • Closing up to 1.0 m/s
  • Highest wind load capacity
  • Top safety devices
  • Up to 250,000 operating cycles p.a.
  • Standard sizes of up to w=10,000 mm, h=12,000 mm


Cutting-edge insulation Open

As the first manufacturer of industrial doors worldwide, EFAFLEX offers thermally separated EFA-THERM® insulation laths for the EFA-SST® as a standard. Depending on the door size, this allows for outstanding thermal insulation values of between 0.66 and 1.52 W/m² K to be achieved. Thanks to the fast opening and closing speeds of our industrial high-speed doors, little energy is lost to the outside or between two rooms.

Versatile door leaf Open

The door leaf for the EFAFLEX industrial door is extraordinarily robust, tight and sound-insulating. You can determine the required number of EFA-CLEAR® transparent laths for your EFA-SST® according to the desired incidence of light. The EFAFLEX spiral does not wind the door blade onto a shaft, but keeps it at a distance to save space. This design optimally combines highest opening speeds, durability and effectiveness.

Individual design Open

In addition to the standard aluminium-coloured coating, we are also able to paint the door’s laths and steel parts in almost any colour from the RAL system on request. In this way, the doors can be perfectly adapted to the architecture and any façade and blend in perfectly with the appearance of your company premises.

Variable solutions Open

Our high-speed spiral doors have the circular round spiral, the best solution for the fastest opening and closing times, as a standard. If the space above the door is limited, you can also choose between two space-saving variants for many door types of the S series: oval spiral and low lintel.

High-end safety technology Open

As the world’s leading manufacturer of high-speed doors, it is our aspiration to also be pioneers in the field of safety: All EFAFLEX products meet the highest standards and protect both people and the goods as well as the door itself. It is not only our industrial doors that impress with their state-of-the-art safety technology, but also the associated systems: EFA-SCAN®, for example, is the world’s first laser scanner for use on doors, which is a reliable pulse generator and safety system in one.
