Steel Cladding Wind Load Span Graphs

Wind Load span graphs should be read in conjunction with the constraint of access and the span at which the point load will be the limiting factor.

The performance of profiled metal cladding depends on the profile shape, thickness of the metal, the span, and the fastening type and pattern. These values can be greatly enhanced by using load spreading washers or thicker material.

All the tests from which these graphs have been derived used the 2:3 ratio of end to intermediate span and the graphs shown are for intermediate spans only. End spans must be reduced by two-thirds for these values to be assumed.
