About HiKlip® 630
High and mighty, HiKlip® 630 is the largest water-carrying concealed-fixed roofing in Australia. Purposely built to survive the strongest stormy weather for major commercial, industrial and domestic projects. HiKlip® 630 ensures ultimate protection, strength and durability, with large span capabilities that deliver on value, ensuring fewer purlins and lower costs.
Stylish as well as strong, HiKlip® 630 has been described by architects as striking, imposing and bold. Available in a range of COLORBOND® steel light and heavy gauge colours, HiKlip® 630 is truly aesthetically pleasing. HiKlip® 630 can be produced with the Fielders Mobile Mill, available to be made onsite and in real time to suit the required length.

Allowable Spans
The allowable roof spans for the HiKlip® 630 roofing profile in Regions C and D are shown in Table HK RS CY 001 and Table HK RS CY 002.
The allowable spans have been determined from tests carried out in accordance with NCC (BCA) 2016 Specification B1.2 for the LHL cyclonic testing method, AS 1170.2-2011 and AS 4040.0-1992.
Figure HK CY Local Pressure Factors 002
Note:
1. The local pressure factors (KL) are shown in Figure HK CY Local Pressure Factors 002 are not applicable at the ridge where the roof pitch is less than 10°. The value of ‘a’ is the minimum of 0.2 breadth, 0.2 width or the height.
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 CY 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 CY 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.
Fixing of Cladding
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.
All fasteners used externally should be fitted with an EPDM seal. Do not use punches to form fastener holes. For a concealed-fixed cladding, the clips are fastened to the support at the base of each rib, as shown in Figure 2.7.C. Fasteners used in the clip fixing is shown in Table HK CF CY 001.
For further information on the HiKlip® 630 roofing profile, including installation procedures, refer to the “installation procedure”.

Concealed Fastening
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.
Further details are available in section “Comparative Analysis: Concealed Fix vs. Screw Fix”.

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.
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.
Figure HK CY Clips Located By Fixing Centre Screw First 004
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 CY HiKlip®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 deck-ing 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.
