Patented quality, it’s in the detail

 

 

Perfected technology

 Space saving:
Refined lifting mechanism makes it possible: Even high vehicles like minibuses or people carriers need barely a handbreadth’s distance to the closed door.

Durable:
All steel parts are galvanised, door skins are fastened with decorative aluminium rivets or screwed. Doors have no welded parts, which means that the rust-resistant zinc layer remains intact. A double layer of stove-enamelled plastic on the steel panels contributes to the durability of the door and locks out rust.
   

Simple, fast and quiet:
Normstahl One-Piece-Doors operate with a sophisticated lifting mechanism with no intrusive ceiling rail runners. This has many advantages: a fully pre-assembled door is easy to install - irrespective of the ceiling or walls. Plus, there are no irritating additional noises caused by resonance transfer to the ceiling. That means the door is always quiet.
