Doors and gates in street tunnels

Flight – Rescue – Ventilation – Fire protection – Maintenance – Longevity Road tunnels are a challenging environment for doors.

The special requirements for doors in road tunnels include:

The highly corrosive climate with its mix of exhaust gases, moisture

• Heat, road salt that has been brought in
• Mechanical and dynamic loads from passing vehicles, especially lorries
• Intensity of use and expected constant availability
• Diversity of users and limited training or education opportunities- or
• Control options; accordingly, a broad spectrum of safety and rescue scenarios

The answer to these requirements is a combination of mature products, individual engineering, high-quality materials and processing, professional assembly and efficient service. Numerous references confirm our many years of successful implementation in practice.
