Product Details

Power driven helical screw piles for building

Product Description

Round shaft helical piers

*Shaft material: Seamless high tensile pipe, conforms to ASTM A500 GRADE B
*Helices material: ASTM A36 Hot rolled plate
*Corrosion protection conform to ASTM A153 standard for hot dipped zinc coating
*Round Shank Anchors are Hot Dip Galvanized to meet ASTM Specification A153.
*Leading edge of Helices beveled 45 degrees
*Greater Section Modulus Strength to resist Twisting and Deflection
*Greater Load Capacities

Square Bar shaft helical pier

*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
