Install LYSAGHT MULTILINE® cladding

This page details the installation of LYSAGHT MULTILINE® cladding to a steel building frame. For more information see Install LYSAGHT® Steel Roofing & Walling

Please be aware that installation of cladding must be carried out by a licensed tradeperson in some Australian states.

Installation

Install LYSAGHT MULTILINE® panels from the ground up with each subsequent sheet lapping over the previous sheet. The two methods of lapping recommended are the Edge Lap joint and Pan Lap joint as depicted below.

Screw each sheet to supports behind at every flat contact area 150 mm apart. Ensure each fastener is straight and not over tightened.

Location of Fasteners

One fastener should be placed each side of a lap and vertically at every pan, unless otherwise noted.

Fasten horizontally at 300mm centres where supported with No.10 - 16 x 16 wafer head self drilling screws to either:

  • 1.2mm BlueScope Lysaght standard stud
  • 0.60mm or 0.75mm LYSAGHT SUPRAFRAME® stud.

Accessories and Tie-Down

Notes:

  1. PVC foam shall be grade "SOFT"
  2. Applying large beads of silicone to each surface may assist the placement of PVC
  3. Fasten flashing with No.10-16 x 16 wafer head screws at each crest of the cladding.

Sealed Joints

It is not practical to solder ZINCALUME® steel, so where joints are required use 10 - 16 x 16 wafer head screws and silicone sealant.

Only sealant branded as suitable for use with galvanised or ZINCALUME® steel should be used.

General Notes

Adverse Conditions

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

Metal & Timber Compatibility

Lead, copper, free carbon, bare steel and green or some chemicallytreated 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.

Handling and Storage

Keep the product dry and clear of the ground. If stacked or bundled and the 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 each other; don't drag tools over material; protect from swarf.

Care and 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.

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.
