Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Specically dimensioned strand bigger than 4 in. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to q586 its use and application.

Galvanized Structural Strand ASTM A On Lexco Cable Manufacturers

Specimens shall be tested and conform to values of the following physical requirements: Class C Coating Outer Wires In addition, WW can obtain material certification from end termination vendors. Last previous edition A — Find a state or province to view Wirerope Works, Inc. If both of these two samples pass the retest for breaking strength, the manufactured length in question shall be accepted.

Welds made in the outer wires prior to drawing are permitted. Strands shall be furnished with Class A weight zinc-coated wires throughout, but may be furnished with Class B or C weight wires as well where additional corrosion protection is required.

Structural wire rope provides greater flexibility when compared with coarse strand constructions and is generally the structural cable of choice where bending ability is an important requirement, such as forming flemish eye ends drop terminals. Link to Active This link will always route to the current Active version of the standard.


Maintain this load while a in. Historical Version s – view previous versions of standard. The stress corresponding to this load shall meet the requirements for s586 stress of 0. In doing so, we are able to test and certify the following:. Loosening or detachment during the adherence test of supercial small particles of zinc formed by mechanical polishing of the surface of zinc-coated wire shall not be considered cause for rejection.

ASTM A586 – 04a(2014)

The higher strength results in an increased design factor of the guying system. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. The modulus of elasticity shall be atm from gage length of not less than in.

Any test, however, which fails due to faulty attaching of the sockets shall be disregarded. If both of these tests pass, the coil or reel shall be accepted.

Record the load for this extension. Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. The base metal shall be carbon steel manufactured by the open-hearth, basic-oxygen, or electric-furnace process Finished strands and the hard-drawn individual zinc-coated wires shall be coated by the hot-dip or electrolytic process.

Then increase the load uniformly until the extension recorded by the extensometer is at least 0. NOTE 2—The extensometer used for the stress at 0. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The coating shall be continuous and reasonably uniform. Using SS also offers these advantages: Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur.

Using SS also offers these advantages:. For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. This specification covers zinc-coated parallel and helical steel wire structural strands for use where a high-strength, high-modulus, multiple-wire tension member is desired as a component part of a structure.

Smaller Fittings—Many fittings manufactured for standard strand may be used with the SS, thereby offering a lower cost per unit and adding further cost reductions. Refer to Table 1 for structural strand data. Work Item s – proposed revisions of this standard. Product description Prestretching Striping Proofloading Pin orientation Certification Special features Length tolerances Galvanized coating Modulus of elasticity Length and point of measurement Measuring at required load End terminations dimensions, pin sizes, jaw openings Nondestructive test method.

These are the features that permit strand to adapt so successfully to structural applications. For any given diameter, wire strand is the least flexible of steel cables. Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section. Test for Coating Weight 6. The number of layers and number and size of wires in each layer shall be determined by the manufacturer.
