Wesupply screw piles with cold-formed helical plates (also known assectional flighting, or helices) which are formed by a specializeddie. The physical properties of the steel remain unchanged duringthe forming process, which contributes to accurate outside diamter(OD), inside diameter (ID) and pitch and perfect a right anglebetween helical plate and shaft. The perfect helical surfacecontributes to a successful installation of screw piles withminimal soil disruption and optimal load transfer.

Product quality:
1.1 Aperfect fit between helical plate and shaft
1.2 Perfect helical surface, smooth openingangle,which contributesto a successful installation. Its perfect helical configuration foran angle will develop a clean rotation through the soil, whichleads to a successful installation and minimum soildisruption;
1.3 Welding isperformed by AWS or CWB certificated welders.
