Protecting your property is one of our core values. When you add wind load options to your commercial or industrial door, you also get peace of mind during times of high winds from hurricanes and extreme conditions.Wind loading of doors is a common technical attribute that is looked for in doors, but in some cases, not well understood.
The valid standard commonly used for the information relating to wind loads in power-operated doors is DIN EN 12424. This standard defines the classification of the wind loads for doors when closed. To this end, the wind load is understood as the differential pressure from one side of the completely closed door to the other side; there is no information relating to the running performance for a door under wind load.
The standard distinguishes between 5 wind classes, where class 0 provides no information on the wind load, and always applies when no measurement is being carried out.
Disregarding various general conditions, such as installation situations and geographic influences, the following table can be used as a guide for the approximate conversion of wind speeds.
Wind Class | Comparison Wind Loading | Wind Speed | Wind Speed |
DIN EN 12424 | Pa=N/m2 | m/s | km/h |
0 | 0 | 0 | 0 |
1 | 300 | 22 | 80 |
2 | 450 | 27 | 100 |
3 | 700 | 34 | 120 |
4 | 1000 | 41 | 150 |
5 | 1600 | 51 | 180 |
Installing a door with the correct wind loading is very important, as there are many reasons why it is important that doors do not fail. In non‐cyclonic areas, any such failure can pressurise the building and lead to other structural failures such as failure of the roofing system. In cyclonic areas, this internal pressure may already be allowed for but door failure can either result in further damage from the flapping door or the door itself can become a danger to life and property if it fully disengages. Another key issue from a door failure is water ingress which can lead to loss of amenities or damage to contents.
Our experienced team can guide you in the process of door selection for your application, to ensure it meets all environmental requirements.
