 Helical anchors are used for new construction and to support existing structures. They are designed for applications in expansive soils, high water tables, fill areas, and other areas where unstable soils require a deep foundation. In compression they are used as footers and in tension they may be used to support retaining or foundation walls. Helical piers are round or square, tubular or bar steel shafts with round helix plates welded to them.
Â
Square Bar Shaft screw piles
1. Bar Material: 40Cr or 45# steel, round corner 5mm radius.
2. Helix Plate material conforms to ASTM A36 hot rolled plate .
3. Helices thickness are available in 3/8†and 1/2†inch.
4. All helix leading edges sharpened and rock cut and 45 degrees.
5. Corrosion protection to conform to ASTM A153 standard for hot dipped zinc coating.
6. A better conventional solid steel extra high strength helical screw pile
7. Welded coupling for greater strength. Eliminates shaft heat damage caused by upset coupling process.
