Commercial & Industrial Foundation Helical Screw Anchors

Commercial & industrial foundation Helical Screw Anchors   Helical piers 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.      Commercial & industrial foundation Helical Screw Anchors  --Specification   Shaft size 2 7/8" Tubular-0.203"wall 2 7/8" Tubular-0.262"wall 3 1/2" Tubular-0.300"wall 4 1/2" Tubular-0.337"wall 1 1/2" Square Bar 1 3/4" Square Bar 2 1/4" Square Bar Material 40Cr ASTM-5140 Helix Diameter 8" 10" 12" 14" etc Thickness 3/8", 1/2" etc Material Q235 (ASTM A-36) Number 1,2,3,4 or more Finish Plain, Hot Dipped Galvanized, Painted, Powder Coating etc   Notes: Other sizes are available upon request.   Commercial & industrial foundation Helical Screw Anchors--features   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.
