Water Carrying Capacity and Rainwater Run-off
The Right Profile For the Right Job
In Australia, we experience vast differences in regional conditions as well as variations in the functional and performance requirements of buildings, yet most roofing manufacturers offer the same profiles for all applications.
Fielders® provide the largest range of long length concealed fix decking on the Australian market. Each profile has been developed to give maximum performance in a variety of applications, giving you the right roofing profile for any conditions.
Figure DD WCC RD 001
Note:
Figures based on exposure conditions as follows:
1. Rainfall intensity - 370 mm / hr (Cairns 100 year).
2. Roof Slope - 5.0 degrees.
3. Flow condition - Steady state & uniform.
4. Flow (L/s/m) - Per metre width of sheet.
Fielders® three concealed fix roofing profiles have all your requirements covered. KingKlip 700® is a premium wide deck with a clip design allowing faster installation. And finally, HiKlip® 630 has the greatest water carrying capacity on the market.
All concealed fix decks are backed by Fielders® unique 20 Year Watertight Installation Guarantee - and more importantly, they have no more holes!
Fielders® HiKlip® 630
HiKlip® 630 is the strongest concealed-fixed roofing product, and secondly, it has the greatest water carrying capacity of any deck on the market.
Fielders® recognised the demand for a concealed fix deck that provided total protection for buildings located in areas prone to flash deluges, high wind and rainfall. The result was that Fielders® designed HiKlip® 630. HiKlip® 630 is a revolutionary deep rib deck with two important performance features.
Both the HiKlip® 630 deck and clip mechanism exhibit great strength and are able to resist very high wind pressures whilst allowing the brackets and decking to slide independently of each other to accommodate temperature variations without unsightly step joints.

Data for other locations may be obtained from local drainage authorities. Data for any locality in Australia (to a resolution of 1/40th of a degree of latitude or longitude) may be obtained from the Bureau of Meteorology.
Data shown for large cities are the maxima within the greater city area. Data for specific locations within these areas may be obtained from the Bureau of Meteorology.
More stringent requirements should be considered for buildings where the avoidance of gutter overflow is of paramount importance.
All gutters and outlets, particularly box gutters served by internal sumps, need to be regularly inspected and maintained to avoid breakages.
