Description
PS9 Metal Webs give a 225mm deep joist with a maximum Clear span of up to 5700mm (5.7m)
This joist profile also gives you a clear service void of 131mm between the timber flanges.
As there are so many design solutions and ways to meet your span, the actual span can only be calculated by our experienced designers who will take into account many factors such as your floor loads, design space of joists, depth of your floor zone and services.
The maximum spans shown here are examples of what are most likely to be achieved, assuming that:
