Heavy Duty Earth Anchors for securing guying wires, security, and or structure securement.

Anchors are installed by simply turning the anchor into the ground, utilizing a turning bar placed through the anchor's forged eye. No Wrench Utility Anchors can be installed by hand or by machine.

Screw Anchors consist of a forged triple eye rod with an angled point, and a firmly welded helix.

Ground Anchors are hot dipped galvanized to meet ASTM Specification A153, Class C for long resistance to rust


 Soil Classifications

Class 5: Medium dense coarse sand and sandy gravels; stiff to very stiff silts and clays Saprolites, residual soils

Class 6: Loose to medium dense fine to coarse sand; firm to stiff clays and silts Dense hydraulic fill; compacted fill; residual soils

Class 7: Loose fine sand; Alluvium; loess; soil-firm clays; varied clays; fill Flood plain soils; lake clays; adobe; gumbo; fill

Anchor requirements are site specific. Soil type should be determined to assure that the correct anchors are used. Seek professional guidance. Anchors must be installed at an angle of 45 degrees in the direction of the guy load. Failure to install within 5 degrees of alignment of the guy load will significantly lower strength. Capacity ratings apply to properly installed anchors only.

Holding strengths are based on the approximate industry standards. Determining soil load capacity is an inexact science limited by an inexact environment, from all of the unknowns both below and above the surface of any anchoring application – the soil medium, installation method, local climate, connections to the anchored structure – no one can guarantee a specific holding strength. Load capacity is not a simple function of “soil class” but also of real-time moisture content, compaction, root penetration, installation method, pullout load angle, and other factors unique to the installation’s time and place. Therefore the only way to truly determine ‘holding strength’ is on-site specific probing and testing.
