Square bar shaft helical piles
Bar Material: 45Cr or 45# steel, round corner 5mm radius.
Helix plate material conforms to ASTM A36 hot rolled plate.
Helices thickness are available in 3/8" and 1/2".
All helix leading edges sharpened and rock cut and 45 degrees.
Corrosion protection to conform to ASTM A153 standard for hot dipped zinc coating.
A better conventional solid steel extra high strength helical screw piles.
Welded coupling for greater strength. Eliminates shaft heat damage caused by upset coupling process.
