Fastening
Clip specifications may vary from state to state, refer to your local Fielders' representative for clarification.
Clip Fixing
Fasteners must be selected to match the life expectancy of the cladding material. Recommendations from fastener manufacturers should be sought. Only fasteners complying with AS 3566:2002 and those that are compatible with the roofing material should be used for its fastening.
Insulation
Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm is installed the screws detailed in Table KK RF 001 may need to be increased depending on the thickness and density of the insulation. When the screw is properly tightened into metal there should be a minimum of three (3) threads protruding past the support being fixed in to. For timber, the screw must penetrate the timber as much as the screws detailed in Table KK RF 001 do without insulation. For insulation thicknesses greater than 50mm, Fielders® recommend using a thermal spacer or alternate solutions such as Lysaght SUPABRIDGE™ to help maintain Rw values and minimise any bulging in the profile caused by the insulation.
KingKlip 700® Installation Procedure with Mk3 SuperKlip
Refer to "Maintenance and Care" for general handling instructions.
Step 1
Fix the first two clips, with the arrow on the clip pointing towards the area to be laid, perpendicular to the gutter in a straight line using the correct fasteners. Use a string line or the edge of the first sheet to ensure straightness. Care should be taken so that the overlap is facing away from the prevailing wind.
Step 2
Locate the first sheet above the clips ensuring that the overhang into the gutter is correct. Push downwards on the sheet until the decking is secured at every clip. Do not use excessive force.
Step 3
Locate the next clip. Align the holes on the two clips and fasten with screw. Insert all screws for the clip. Fasten all clips in this manner.
Step 4
Lay the next sheet of KingKlip 700® as previously. Checks should be made periodically to ensure the decking is installed squarely. This can be done by comparing the coverage at the ridge and gutter line. At the end of the purlins, cut the deck and the clip to suit.
Step 5
Turn up KingKlip 700® pans at the ridge line. On lower pitches, pans should be turned down at gutter line.
Step 6
Flash the roof with compatible products using F10 bracket and sliding brackets, to allow for thermal expansion and contraction.
Step 7
Clean the roof daily during construction as per Fielders® maintenance guide, removing all swarf, pop rivets and fasteners.
Note:
1. Foot traffic should be restricted to the pans of the decking.
Turning of Roof Sheeting Ends
Refer to section “Flashings, Cappings & Ends of Sheets”.
Designing Without Step Joints
Refer to section "Long Length Roofing Solutions".
Maximum Sheet Length

Notes:
1. * denotes size to be determined by application. All sizes are in mm and should be used as a guide only. They should be measured on-site to determine actual size.
2. S.B. denotes ‘Slight Break’.
3. Also refer to “Typical Roofing Details”.
KingKlip® 700 Sliding Bracket for Flashing Installation
The installation of this flashing must allow for movement between the roof sheeting and the wall parallel to the edge of the sheeting. The following fixing procedures are recommended.
Note: Where overlaps occur on the roof a corresponding overlap is to be made in the barge flashing. Be careful when moving between supports. Do not walk in the pan immediately adjacent to flashings or translucent sheeting. Walk at least one pan away.
Typical Barge Flashing Detail
Sliding Bracket Assembly

*Notes:
1. Locate sliding bracket away from supports
2. Spacing of sliding bracket as per AS 1562.1
Cyclonic wind regions: 500mm centres (max)
Non cyclonic wind regions: No more than support spacings
3. *Clearance to prevent fastener interferences
4. Barge dimensions and positioning to cladding to comply
with relevant standards, legislation and accepted trade
practice.
