What Wind Load Ratings do Industrial Doors Require in the UK?
In the UK there is no single universal wind load rating that all industrial doors must meet. Instead, each door should be designed and classified for resistance to wind load in accordance with BS EN 12424, with the required class determined by the building’s design wind pressure, door size and site exposure.
BS EN 12424 defines a series of wind load classes based on the pressure that the closed door can safely resist. For most external industrial doors on typical warehouse or factory units, a minimum mid-range class is normally recommended, with higher classes specified for very large openings or highly exposed sites. The project’s structural engineer or designer should confirm the design wind loads for the building, and the door specification must meet or exceed those values to ensure stability, safe operation and long-term reliability.
When we specify industrial doors, we match the wind load class of the chosen product to the calculated site conditions and door size. Many modern sectional and roller shutter doors are available in several tested wind classes, so an appropriate solution can be selected for everything from standard industrial units through to very exposed coastal or high-wind locations.
