How To Install LYSAGHT WALLCLAD® Cladding
This page contains tips on the installation of LYSAGHT WALLCLAD® sheeting. For more information see Install LYSAGHT® Steel Roofing & Walling.
Please be aware that installation of steel cladding must be carried out by licensed tradespeople in some Australian states.
Installation
LYSAGHT WALLCLAD® is fixed in place by valley fastening. Three or five fasteners per sheet per support may be used, dependent upon the wind loading conditions.
Side lap fasteners are required adjacent to valley fasteners at each lap at each support.
End laps should lap a minimum of 100 mm.

Metal and Timber Compatibility
Lead, copper, free carbon, bare steel and green or some chemically-treated timber are not compatible with this product. Do not allow any contact of the product with those materials, nor discharge of rainwater from them onto the product. Supporting members should be coated to avoid problems with underside condensation. If there are any doubts about the compatibility of other products being used, Contact Us.
Maintenance
Optimum product life will be achieved if all external walls are washed regularly. Areas not cleaned by natural rainfall (such as the tops of walls sheltered by eaves) should be washed down every six months.
Storage and Handling
Keep the product dry and clear of the ground. If stacked or bundled product becomes wet for extended periods, separate it, wipe it with a clean cloth to dry thoroughly.
Handle materials carefully to avoid damage: don't drag materials over rough surfaces or over each other; don't drag tools over material; protect from swarf.
Cutting
For cutting thin metal on site, we recommend a circular saw with a metal-cutting blade because it produces fewer damaging hot metal particles and leaves less resultant burr than does a carborundum disc.
Cut materials over the ground and not over other materials.
Sweep all metallic swarf and other debris from roof areas and gutters at the end of each day and at the completion of the installation. Failure to do so can lead to surface staining where the metal particles rust.
Sealed Joints
For sealed joints, use screws or rivets and neutral-cure silicone sealant, branded as suitable for use with galvanised or ZINCALUME® steel.
