Sectional door SECTIOLITE ST40T with pass door

The door for combined vehicle and pedestrian passages

SECTIOLITE is the new name for the former door type SPACELITE HTU.

In some buildings the access for vehicles and for pedestrians cannot be separated. In these cases SECTIOLITE ST40T can be equipped with a robust pass door, perfectly integrated in design and function. Besides the benefits of a sectional door and those of translucent fibreglass panels it thus also permits a fast and safe personnel traffic, without the need to open the sectional door. SECTIOLITE ST40T fulfils this multiple use over the entire life cycle in a very economic manner, by means of its solid and durable technology without wear-sensitive components such as torsion springs.



Opening function for vehicle and pedestrian traffic:

  • Integrated pass door: ideal in situations where a pedestrian door cannot be installed besides an industrial door
  • No risk of stumbling: The low, nearly barrier-free threshold avoids accidents
  • Solid design for door and passage door, with coordinated safety features
  • Ceiling tracks made of galvanized steel with 90° deflection. Optionally guided along the roof or vertical tracks
  • Solid lateral tracks made of friction resistant aluminium, with detachable covers, for safety reasons closed on three sides

Pass door

  • Completely integrated, position in the door centre
  • Barrier free threshold, only around 20 mm high
  • Frames made of solid aluminium profiles with EPDM gaskets and high quality hinges, with top closer
  • Safety aspects of industrial door and pass door in line

Fibreglass – a unique material for industrial doors:

  • Light transmission up to 78% for bright working areas inside the building
  • Diffuse light without cast shadow for a perfect view and a comfortable working environment
  • Less need for artificial lighting during the day
  • Three colours to choose from: Brilliant, Emerald-Green or Sapphire-Blue
  • Optional vision panels made in SAN- double or triple glazing
  • Design perfectly combinable with other SECTIOLITE or SPACELITE fibreglass doors and the VARIOPLANplus fibreglass curtain wall

Reduced cost for operation and maintenance:

  • Electric drive with an extremely resistant and enduring gear motor
  • Direct drive without additional wear-and-tear-sensitive parts such as torsion springs
  • Micro processor control for trouble-free and comfortable operation


  • Passive safety: No protruding hinges or reinforcements, no suspending cables or wires, no trapping and shearing edges
  • The sectional door can only be activated if the pass door is closed properly
  • Anti-jamming protection: All stacking doors are equipped with a safety edge. After contact with an obstacle the door stops and re-opens automatically and instantly
  • Access protection: Hit-proof fibreglass panels and automatic anti-lifting device
  • Anti-fall protection: falling door panels are caught and stopped immediately (certified by the TÜV, German technology supervision agency)
