Maximum Spans and Fastening Patterns for Corrugate Wall Cladding

The maximum span for pan-fastened wall cladding is generally governed by temporary deflection under load, rather than permanent deflection around the fastener.

A printable bulletin is available at: BCVW01 Support Spacings on Corrugate Wall Cladding

Extract:

"The Metal Roofing and Wall Cladding Code of Practice (COP) can be used to support designs for
vertical corrugate cladding at spans greater than 480 mm. These spans are less than what is quoted
for roofing, because in the case of wall cladding we have limited loads to a deflection limit as
described in the attached table."

Maximum Span for Wall Cladding: 5 Fasteners per Sheet (every second trough)

*Serviceability load governs 
The deflection criteria used in this table is span/120 + P/30, where P = the space between fasteners. Higher deflection limits may be acceptable in certain circumstances.
