INNER STRENGTH OF STEEL

The shake Panel is made from *Zincalume” steel which is aluminium-zinc coated steel. The barrier protection of aluminium and the sacrificial protection of zinc is combined to provide protection for the steel substrate of Shake Roofing. The acrylic basecoat, granules and acrylic overglaze to provide protection to this alloy coating further enhancing its durability.

*Zincalume® is a registered trademark held with the BHP Group of Companies

COATING SPECIFICATION

Transparent coatings

Both sides of the Zincalume* steel are coated with a pigmented transparent coating that provides protection and a uniform substrate for further coatings. This transparent coating allows identification of the aluminium-zinc substrate to be made by distributors and customers.

Basecoat with Satin finish:

A tough opaque coating based on a 100% acrylic resin. This coating contains additives toxic to biological growths such as algae and lichen.
Paint finish: 100% Acrylic finish applied to panel giving it a low gloss, low sleid coating with superior scratch and fade resistance.
Textured finish (Available upon request): Carefully selected granules provide excellent surface coverage and attractive natural lasting .colours.
Overglaze: Clear 100% acrylic resin coating for granule binding and a semi-gloss finish.

THE STORM AND WIND TEST

The hurricane test by Construction Research Laboratory, Inc., Miami, Florida, USA. Testing was carried out in Florida, in the southern United States, an area which, because it experiences regular hurricanes, has strict regulations. The AHI Roofing tile panels were laid in the normal manner, horizontally fastened to wooden battens which were fastened to the plywood under-deck.

The air stream was provided by the propeller of a 100 kW aircraft engine wind generator. Water spray was added to the air stream upwind of the eave at a rate equal to 200 mm of rain per hour. The roofing panels and the underdeck were checked for any uplift or leakage. The wind speeds were increased steadily to 160 kilometres per hour. No leakage occurred even after prolonged exposure. The roof remained firm and no uplift was observed.

Extreme Wind Resistance on Various Roofs.

Further Testing

The cyclone loading test to the Wind Loading Code, Australian Standard 1170, part 2, 1975, by Cyclone Testing Station, Australia.
The high speed dynamic rain penetration and high wind loading test by Construction Research Laboratory, Inc., Miami, Florida, USA.

The Heavy Rain Test

The low speed dynamic rain penetration test by the Commonwealth Scientific and Industrial Research Organisation’s experimental building station. The Australian CSIRO’s experimental building station has an apparatus for low speed dynamic rain penetrating tests. A 1200 mm-diameter 8-blade fan is driven by an 18.65 kW electric motor. The windstream from this fan is discharged into the test chamber via a 2130 mm square duct. Water is introduced into the wind stream and can be directed horizontally, vertically or any direction in between. Under all angles, and with a water application of 50 millimetres per second per square metre of roof area.
