Ground Screws are forged from a single piece of steel tubing and galvanized
to German and international ISO standards. Com-
plying
with Australian Standards, the Building Code of Australia and certified
by structural engenieers the screws
have a life expectancy of 20 to 25 years depending on soil and climate
conditions. Con-

in that process releasing chemicals which are not conducive to the environment.
