Install LYSAGHT TRIMWALL® cladding

General tips on the installation of LYSAGHT TRIMWALL® cladding. 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 TRIMWALL® is fixed in place by valley fastening next to each rib - four fasteners per sheet per support. Side lap fasteners are required adjacent to valley fasteners at each lap at each support. Should it be necessary to have end laps, allow a minimum of 100 mm.

Adverse Conditions

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.
