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.
Make sure that the supporting structure is as rigid and flat as possible. The tables in this brochure are based on sheets being overlapped by 1.5 corrugations.
Always use at least two people to install LYSAGHT MINI ORB®.
Support Spacings
For best aesthetic results an all installations, limit support spacings to 900mm maximum. For walls follow the table Maximum Support Spacings in Download LYSAGHT® Walling Solutions (886 KB)
Ceiling Installation
Start fixing near the centre of a sheet, on one edge, and work outwards towards the ends of sheet.
Wall Installation
LYSAGHT MINI ORB® can be installed with the corrugatons running vertically or horizontally.
Trimming
MINI ORB0® trims vary in availability and dimensions from region to region. For local availability, please contact your local BlueScope Lysaght office.
Trims
Fasteners
For ceilings, fasteners may be placed along the sheet at up to 1200mm centres.
MINI ORB® should be fixed to all intermediate battens or studs to prevent noise if the sheet flexes with pressure fluctuations in the building.
| Fixing to steel Total thickness up to 3.0 mm BMT |
Fixing to timber | |
|---|---|---|
| Valley Fixed | Ripple Teks® screws 10-16x20 |
Ripple Teks® screws Softwood & Hardwood 10-16x30 |
| Side laps: Sealed blind rivet Ø3.2mm (if required) | ||
Notes:
- For other steel thicknesses not specified, seek advice from screw manufacturer.
- Values given are: gauge/threads per inch/ lengths (mm).
- Care is required during installation to prevent stripping of thin material.
- Screw specification as above or equivalent fastener.
- Ripple Teks screws are not available in Class 4 coating.
Number of fasteners per sheet depends on wind pressure. Fix fasteners no less than 15mm from ends of sheets.
Horizontal Corrugations
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.
Vertical Corrugations
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.
