Fixing information

Care must be taken when fitting panels with flat tray pans to avoid causing dents and creases to these un-stiffened and delicate areas.

The Minimum Pitch is 7.5 degrees for roofing applications. Maximum unsupported overhang is 60mm for roofs and 100mm for walls. Do not allow traffic on completed roof. If required provide cushioned walk boards.

Drip edges should be formed at gutters to prevent capillary caused leakages.

Panels should be fixed to:

15mm CD grade plywood substrate on a maximum support spacing for plywood substrate of 540mm centers or for 17mm CD grade plywood substrate a maximum support spacing of 600mm centers may be used. All Plywood joins and edges must be flush and true. Uneven substrate may cause increased unwanted aesthetic imperfections to be visible.

A Breathable vapor barrier such as CSR “Proctor Wrap RW” for walls or “ProctorWrap HT-R for roofing” or Fletchers “Sisalation Vapawrap Metal Roof” should be fitted beneath Nailstrip sheeting and laid over plywood (or steel battens) prior to fixing.

The sheet shall be fastened through the Under-lap slots with 10g-12x25 Wafer-head screws (class 3 or equivalent recommended). Fasteners shall be spaced at 300mm centers. Fix at center of slots to allow thermal movements. It is important to select a flat headed screw that will not cause dents to the sheet when fitted. Do not over tighten screws where it is desirable to allow sheets to expand and contract with thermal effects. Remove the protective film prior to fitting panels. Where cladding is fitted to a roof with pitch less than 7.5 degrees, the laps shall be sealed with neutral cure silicone sealant.

IMPORTANT: Avoid standing on panel ribs for roofing applications to avoid denting and damaging sheeting. If required provide cushioned walk boards.

Thermal expansion of the sheeting is 2.9mm on average per 5 meters of sheet length for 50 degrees Celsius temperature change. No warranties against thermal expansion noise are provided. Using a quality vapor permeable water proof barrier may reduce noise from thermal expansion and contraction is recommended. Thermal expansion must be considered when determining sheet length and can induce distortion to the panel if the panel is not allowed to freely expand and contract as required.

Sheeting start fasteners and male rib should be flashed over after securing through underlap slots.

Some oil canning effect may be expected and evident in this product and may be caused by a number of reasons. For example, oil canning can be due to un-trueness in the flatness of the buildings substrate, turning up or down the sheet ends (only generally localised to sheet end), effect of thermal change, handling onsite, inherent (and expected) shape in the feed coil; this is expected and common in all flat tray sheet metal products is not a product fault. No warranties are offered against the presence or occurrence of oil canning and shall not be reason for product rejection.

Material Fire Rating

Striproll sheeting products manufactured from COLORBOND®, ZINCALUME® or galvanised steel materials all have an Ignitability Index, Spread of Flame index and Heat Evolved Index of 0 (zero) and accordingly may be used wherever a non-combustible material is called for by the National Construction Code clauses C1.9.(e).(v) and 3.7.1.1.(e).

Tolerance
Coverage: +/- 4mm
Sheet Length: +/- 7mm
End squareness +/- 1.5 degrees, +/- 2.0mm/300mm
Maximum sheet length: 6.000m
Minimum sheet length 0.900m
Lengths over 4.0 may experience increased oil-canning.

Remove all scrap and swarf from completed installation to prevent subsequent Staining from corrosion.

Additional processing service charge for any length shorter than 900mm.

Delivery, Handling and Storage:
Normally delivered to the building site in strapped bundles. If not required for immediate use, sheets or bundles should be neatly stacked clear of the ground and if left in the open, should be protected by loose but secure tarpaulins or similar cover.
On no account should bundles be left exposed to the weather. Rain or condensation are easily drawn in between tightly nested sheets by capillary action, and because of this moisture not being able to evaporate naturally, unsightly stains can be caused which can detract seriously from the finished appearance of the installation.
It is the customer's responsibility to be present or have a representative present, to accept the product in good order and condition upon delivery. The customer is also responsible for unloading their goods.
