SA HB 39 – 3rd Edition – Installation code for metal roof and wall cladding

This Handbook provides information and basic guidelines on the selection, performance and installation of metal roofing and wall cladding. Although the fixing details for roof drainage systems relate mainly to steel, acknowledgment is made of the other materials in common use such as profiled fibreglass reinforced polyester (FRP) and polycarbonate.

When utilised, the design and installation measures contained in this Handbook will provide a weatherproof exterior and ensure that all rainwater is directed to the stormwater drainage system.

As the bulk of this Handbook refers to roofing, it is recommended that the user also source any appropriate additional information required for metal wall cladding installations from specific product manufacturers.

NOTE: The general design and sizing principles of roof drainage systems may also be utilised when installing drainage outlets, downpipes and overflow provision in above-ground external areas of buildings such as drains from balconies, patios and the like.
