Continuity

Optimum performance of roof cladding under load depends on the continuity over several spans.

An adjacent continuous span assists the performance of profiled metal cladding, as continuity can reduce deflection up to 50%. In single spans the cladding is free to rotate at each support, but with continuity at a support the cladding is held down by an adjacent span; reducing the rotation and deflection.

Continuity

 

The end span of profiled metal cladding should be no more than two-thirds of the intermediate span for optimum performance under both point load.
