How To Install LYSAGHT MINI ORB® cladding

This page contains basic instructions for installing LYSAGHT MINI ORB® sheeting. For more information see the page Install LYSAGHT® Steel Roofing & Walling, a guide to the correct installation and handling of the LYSAGHT® range of steel roofing and walling profiles.

The supporting structure should be as rigid and flat as possible to ensure an even finish.

It is recommended that at least two people are used for the installation of LYSAGHT MINI ORB®.

Fastening

For ceilings, fasteners may be placed along the sheet at up to 1200 mm centres.

LYSAGHT MINI ORB® should be fixed to all intermediate battens or studs to prevent noise if the sheet flexes with pressure fluctuations in the building.

LYSAGHT MINI ORB® is valley fixed to timber or steel supports. Place fasteners no less than 15mm from ends of sheets.

Refer to wind pressure capacity table to select quantity of fasteners.

Support Spacings

For best aesthetic results on all installations, limit support spacings to 900mm maximum.

For walls, follow the table Maximum Wall Support Spacings on the page: LYSAGHT MINI ORB®.

Ceiling Installation

Start fixing near the centre of a sheet, on one edge, and work outwards towards the ends of the sheet.

Wall installation

LYSAGHT MINI ORB® can be installed with the corrugations running vertically or horizontally.

Decide how the sheet width will best cover the height of the wall, giving each overlap the same number of corrugations. Overlaps of more than two or three corrugations may detract from the final look of the job.

Start fixing near the centre of a sheet, on one edge, and work outwards towards the ends of the sheet. Place successive rows of fasteners parallel with the first row, working similarly from the centre.

If the sheet is long (about 3000 mm or longer), be careful that the sheet remains straight, along its top and bottom edges.

Follow the same general procedure as that described for horizontal corrugations. Take care when you place each row of screws, that the corrugations are not flattened, thus forcing the sheet to become wider.

End Laps

For aesthetic reasons, end laps are not recommended. See the trimming details below.

Trimming

MINI ORB0® trims vary in availability and dimensions from region to region. For local availability, please contact your local BlueScope Lysaght office.

Adverse Conditions

If this product is to be used in marine, severe industrial or unusually corrosive environments, Contact Us.

Metal and Timber Compatibility

Lead, copper, bare steel and green or some chemically-treated timbers are not compatible with this product; thus don’t allow any contact of the product with those materials, nor discharge of rainwater from them onto the product. 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.
