Square Bar Shaft Helical Piles
Bar Material: 40Cr 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 inch
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 pile
Welded coupling for greater strength. Eliminates shaft heat damage caused by upset coupling process
