Screwpile Australia imports steel tubular product exclusively for the manufacture of its products. All steel is manufactured and mill certified in accordance with Australian Standard AS1163 C350 for Structural Steel Hollow Section compliance.
We have uncovered numerous cases where others have used unidentified or second-hand steels in the manufacture of screw piles. Screwpile Australia is of the opinion that the use of such materials is a questionable engineering practise. In 2004 we became so concerned about the practise we issued press and industry statements highlighting the potential dangers of the unidentified CHS use in screwpile manufacturing.
An independent NATA approved testing consultancy firm was engaged to analyse the use of this steel. It analysed the welding and forming processes of a screwpile components and long term structural integrity of these piles once installed. The report highlighted numerous concerns and summerised that it was impossible to qualify the integrity of such product in accordance with Australian Standards as AS4100 Steel Structures Standard is quite clear on how unidentified steel is to be treated in structural applications.
Screwpile Australia guarantees that all of its product conforms to the relevent Australian Standards and no unidentified or second hand steel is used in its products.
