The underlying technology

Essential aspects

 

Leaving nothing to chance

In an emergency our automatic spring fracture protection reacts in a flash to stop a falling door. The individual door sections are shaped to prevent potential finger trapping openings developing during the opening/closibng process. The hinges are concealed behind protective covers which cannot be removed without tools.

 

Our environmental duty

Our ISO models (40 mm) feature a sandwich construction of FC-free poyurethane foam sandwiched between steel skins. This saves energy, protects the environment and contributes to soundproofing.

 

We’ve thought of everything

Euro Plus

The Plus in visual appearance and impermeability. The covers beautify the inside view (complete surface in RAL 9002) and improve running quality and impermeability of the door.

  

Longer-lasting double protection

Casing corrosion? Not with Normstahl! A special zinc-magnesium alloy provides optimum protection against corrosion and other damaging environmental influences. A pioneer in technology and design, Normstahl makes the most of this knowledge and treats the casings of its Euro Overhead Sectional Doors with this type of alloy. Unlike conventional galvanised steel casings, this method creates double the protection. So it’s ideal for ensuring a long, rust-free life for your door.

  

Safe and dry. Reliable, permanently elastic seals on the lintel, side casings and floor keep your garage dry and safe.

  
 

Sophisticated running mechanism

The weight of each section of our Overhead Sectional Doors is distributed over two tandem running gears each with four rollers. The effect: less roller-stress, less roller resistance and less wear. High-quality snug-fitting plastic curve sections for perfect transitions add to sophisticated running action.
   

Easy to operate.
 

Two torsion springs with spring fracture protection (right and left) make operating safe and simple.

Patented locking system

The brand new locking system, which securely locks the door on both sides, consists of a concealed cylinder, reinforced cable control operation and a locking mechanism integrated into the casing.
