Minimum Roof Slope 

A minimum roof slope of only 1° is required to ensure effective drainage.  However, because the self-weight of the panels causes natural curvature, a minimum slope of 2° applies to spans greater than 4 metres

Testing 

Stramit Building Products employ in-house, purpose-built testing equipment to design, develop and improve products for the Australian market.  In addition, many Stramit® products are tested or witnessed by independent organisations, including The University of Sydney and the Cyclone Structural Testing Station at James Cook University. This ongoing research and development ensures that Stramit Building Products remains at the forefront of innovation, design and customer information.  Testing is conducted in accordance with AS1562 and AS4040.

Installation

Installation and Fixing

Stramit Sunset® Patio Panels may be fixed to support beams, suitably designed receiver channels or to other members with sufficient strength. 

To install Stramit Sunset® Patio Panel effectively, in a typical receiver channel installation: 

  1. Insert foam strip tightly into receiver channel 
  2. To ensure successful interlocking connections, remove the protective plastic coating from the overlapping rib section. 
  3. Lay the first Sunset® panel resting between beam and lower lip of receiver channel, ensuring the panel is pushed firmly up against the foam insert.  Leave a minimum overhang of 50mm at the beam end.                     



    Note: Wall structure must be solid and strong enough to support a fully installed system. 
  4. Secure first panel at beam end using the recommended downward facing fasteners in the correct pan locations.  Tighten fasteners just enough so that the sealing washer provides a watertight seal. 
  5. Secure receiver channel end using recommended fasteners fixed from above.  Do not over-tighten. 
  6. Attach second panel slightly away from the top lip of the receiver channel.  To position the second panel, place the overlap rib on top of the underlap rib of the previously installed sheet, and allow the panel to fall into place (Fig. 1).  To secure the interlocking rib connection, begin at one end of the overlap and simultaneously push down an pull back on the overlap edge until the ribs "click" together (Fig. 2).  Continue along the rib in one direction only.  The panel ribs will automatically lock into position.

    Note: Rib interlocking can be assisted by pulling on the overlap while tapping the rib sides with a rubber mallet, working along the rib in one direction.
     
  7. Slide the second panel up into the receiver channel (Fig. 3). 

    "Position-Click-Slide-Secure" 


    Securing Interlocking Ribs



    Connecting the overlapping ribs may require a little practice at first. Work along the length of the rib and "tuck-in" the underlap by pushing down on the overlap at an oblique angle, while simultaneously pulling back on it.
  8. Secure the panel as before using recommended fasteners and pan locations. 
  9. Repeat procedure until all panels are laid. 
  10. Insert Stramit Sunset® Patio Panel shaped foam inserts using neutral cure silicone to secure and ensure a good weatherproof seal.

  11. Attach weather flashing if required.

  12. Fix gutters, flashing (including edge flashing) or downpipes. 

    Note: When fixing the upper end of Stramit Sunset® Patio Panels to a support beam, note that the panel ends must be turned up and suitable flashing installed to avoid water running along the underside of the panels.
     

Fasteners 

All fastening screws must conform to AS3566 - Class 3.  They are to be hexagon headed and must be used with sealing washers. 

For Steel

  • No. 10 x 16mm hex-head self-drilling, self-tapping screws. Used for downward fixing of panel to support or receiver channel from above
  • 4.8mm diameter alumimium pop rivets. Used for downward fixing of panel to receiver channel from above.
  • No. 12 x 35mm hex-head self-drilling, with dome washer. Used for downward fixing of translucent ribs to steel panel ribs (requires 10mm pilot hole).

For Timber

  • No. 10 x 25mm hex-head self-drilling Type 17 screws. Used for downward fixing of panel pans to support or receiver channel. Add 10mm to screw length for softwood applications.

Screw Fastening Locations 

2 screws per panel fixed downwards at each support 

* Extra screw for edge panel fixed downwards. 

Rivet Fastening Locations

4 rivets per sheet fixed downwards.
 
* Extra rivet for edge sheets 

Installing Translucent Panels 

The following guidelines should be used when installing a translucent panel. 

  • The translucent panel should be attached to at least one steel Stramit Sunset® Panel on the ground first.
  • Before a translucent panel can be placed, there must be at least two steel Stramit Sunset® Panel laid.  This can include the pre-attached steel panel.
  • Two translucent panels cannot be laid next to each other.

Instructions

  1. Pre-cut a notch in the translucent rib, at the receiver channel end only, to allow installation of foam insert.
  2. To fix the translucent panel to a steel panel, it is recommended that the translucent panel first be turned upside down.

  3. With the translucent and steel sheets held at right angles, insert the steel panel overlap rib into the translucent overlap rib.

  4. Rotate the steel panel into position, then firmly press down on the rib union until it securely locks into place.
  5. Flip the attached panels over to the correct orientation and drop them into position on the last fixed steel panel.  Press firmly on all rib unions to secure the join, then slide the panels into the receiver channel.



    Note: A Stramit Sunset® steel panel fixed to a translucent panel is classed as an edge sheet, therefore an additional fastener is required at each support.
  6. Secure using recommended fasteners at the correct rib location and orientation.

  7. The next Stramit Sunset® Panel should then be attached using the "position, click, slide, secure" procedure.

Support Fixings 

Adequate fixing to supports is essential.  Long spanning roofs are usually limited by their support fixings.  Pan-fixing to beams using screws fixed from above is generally satisfactory.  However, attaching panels to a receiving channel or back channel can be difficult.  Span data provided here is based on four carefully positioned rivets, which will generally suffice, provided the rivets are fixed from above.  For further information, contact Stramit Building Products. 

Attaching the receiving channel to a wall or supporting structure may be critical and therefore must be designed to suit each application.  In no case should there be fewer than one wall fixing per panel.  In some cases, many more may be required.

Material Compatibility

All building products need to be checked for compatibility with adjacent materials.  These checks need to be for both direct contact between materials, and where water runs from one material to another.  For this product non-compatibility includes green or treated timber, lead, copper, stainless steel and mortar or concrete.  Contact Stramit Building Products for more detailed information.

Extra

Personal Protection Equipment 

Wear safety glasses with side shields when cutting or trimming product.  Cut-resistant or leather gloves should be worn when handling product.  Foot protection should be worn when handling and transporting product.

Handling/Storage 

Stramit Sunset® Patio Panels should be handled with care at all times to preserve the product properties and quality of the finish.  Packs should always be kept dry and stored above ground level while on site.  If the sheets become wet, they should be seperated, wiped and placed in the open to promote drying.

Cutting 

Stramit Sunset® Patio Panels can be easily cut, where required, using a power saw with a steel cutting blade or a power nibbler and, for localised cutting, tin snips.  Avoid the use of abrasive discs because these can cause burred edges and coating damage.  Dispose of any off-cuts carefully.
