Square Shaft
Consists of solid square shafts, ranging from 1.5″ to 2″. The piles are typically used for ultimate loads between 100 and 650 kN (25-150 kips) but have been tested to loads in excess of 900 kN (200 kips) in unique situations.
Square shaft products are generally used in small to moderate loading applications, and they provide excellent tension resistance. Square shaft piles are able to penetrate dense and cobble-rich soil when compared to their helical pipe pile equivalents, but they have lower resistance to buckling and negligible lateral load resistance.
In applications where tension is the primary consideration, we recommend the Square Shaft Piers. They have several advantages over the typical square shaft anchors.
Square Shaft Advantages:
- Greater yield and Tensile strength
- Patented Cross-bolt Connection
- Increased safety factor
- Higher torque capacity
- Easy to install
- Installs in any season
- Minimal soil disturbance
- Not affected by a high water table
Composition:
- square solid shaft 1 1/2" thru 2″ O.D. typical.
- Solid round cornered Square (RCS), yield strength of grade 70 or 90.
- Ultimate compression/tension axial capacity: 57 to 200 kip.
- Circular tapered plates (helices) are welded to the center of the shaft.
- Helix diameters can range between 6″ - 48″
- with a thickness of 3/8″ - 1″.
- Helix pitch will range from 3″ - 6″
- Hot dipped galvanized per ASTM A123 or bare steel options available
- Coupling bolts are heavy hex bolt as per ASTM A325
- All welding to be done by welders certified of the AWS CODE D1.1
