Non-Cyclonic Load Span Tables
The design pressures and allowable spans have been determined from tests carried out in accordance with the following Australian Standards: AS 1562.1:1992, “Design and installation of sheet roof and wall cladding – Metal” and AS 4040:1992, “Methods of testing sheet roof and wall cladding”. All values are applicable for fixing into a minimum steel support thickness of 1.5mm.

Insulation
Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm are installed the screws detailed in Table HK CF NC 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 HK CF NC 001 do without insulation.
For insulation thicknesses greater than 50mm Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the profile caused by the insulation.
Fasteners - 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.
For Non-Cyclonic regions, 3 screws shall be used per clip.
Recommended Fasteners: Concealed-Fixed
| Supports | Recommended Fastener |
| Steel 1.5mm | No. 10 x 25 mm Hexagon head self-drilling screws for metal |
| Timber Hardwood | No.12 x 25mm Hexagon head Type 17 self-drilling screws |
| Timber Softwood | No.12 x 45mm Hexagon head Type 17 self-drilling screws |
Notes:
- Use three (3) fasteners per clip
- Recommended fasteners shown in Table HK RF NC 001 are for construction without insulation
Laying HiKlip® 630
Step 1
Fix the first of the HiKlip® 630 clips 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 weather.
Figure HK NC Clips Located By Fixing Centre Screw First 004
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
Lap the next HiKlip® 630 clip over the top of the male rib, ensuring that the sheet being laid is parallel to the previous sheet and perpendicular to the gutter line. Fasten this first and fix the remaining two holes as previously done. Fasten all clips in this manner.
Figure HK NC Clips Over The Top Of The Male Rib 005
Step 4
Lay the next sheet of HiKlip® 630 as previously described. Checks should be carried out periodically to ensure the decking is installed squarely. This can be done by comparing the coverage at the ridge to that at the gutter line or by using a string line. At the end of the purlins, cut the deck and clip to suit.
Step 5
Turn up the HiKlip® 630 pans at the ridge line. On lower pitches the pans should be turned down at the gutter line.
Step 6
Flash the roof with compatible products using F10 brackets and sliding brackets as necessary to allow for thermal expansion and contraction.
Step 7
Clean the roof daily during construction as per Fielders® maintenance guide, ensuring the removal of all swarf, pop rivets and fasteners.

Unique double-clip action
Only HiKlip® 630 features an over-and-under double clipping action on the side lap for added strength to withstand the strongest winds. And therefore, because the clips and brackets allow the sheet to move with temperature changes, you do not need step/expansion joints.
