Install LYSAGHT PANELRIB® cladding
Basic tips on installing LYSAGHT PANELRIB®. 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.
Fastening Details & General Notes
LYSAGHT PANELRIB® steel cladding can be attached to the frame with the flutes either vertical or horizontal. When fixing with flutes horizontally, ensure that the top sheet overlaps the sheet below it. If end laps are necessary because of very long runs, allow at least 75 mm lap.
For sheets fixed in external applications where sealing is required, seal end laps with a suitable sealant.
Location of Fasteners
A fastener should be located either at the side lap or adjacent to it. For a quality finish, fasteners at the ends of LYSAGHT PANELRIB® sheets, including end laps, should be located at every second valley. At intermediate supports, four fasteners should be used equidistant across the sheet.
For internal applications not subject to wind loads, the number of fasteners may be reduced by 50%, except for ceiling applications.
Fastener without insulation
| Fixing to Steel up to 3mm thick | Fixing to Timber | |
|---|---|---|
| Valley Fixed | Self drilling screws with hex. washer-head |
Self drilling screws with hex. washer-head Softwood & Hardwood: 10-12 x 20 (M4.8-12x20) |
Number of fasteners depends on wind pressure, for further information, please Download LYSAGHT PANELRIB® (794 KB). Do not fix screws less than 25mm from the end of sheet.
Joining and Edge Treatments
Suggested steel, plastic or aluminium mouldings are illustrated here. Please contact your local office for availability of mouldings.
Side Lapping
Three types of side lapping methods are used: the overlapping flute, the butt joint and the edge lap joint.
When using the overlapping or edge lap joint methods, side lap fasteners are required at 200-300 mm centres.
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, free carbon, bare steel and green or some chemically-treated timber are not compatible with this product. Don’t 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 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..
Safety, Storage and Handling
Handling Safety - LYSAGHT® product may be sharp and heavy.
It is recommended that heavy-duty cut resistant gloves and appropriate manual handling techniques or a lifting plan be used when handling material.
Keep the product dry and clear of the ground. If stacked or bundled product becomes wet, 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 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 when 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.
