For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. Smaller Fittings—Many fittings manufactured for standard strand may be used with the SS, thereby offering a60 lower cost per unit and adding further cost reductions.
The steel shall conform to the following tensile requirements: WW is also ISO certified.
Using SS also offers these advantages: The wire rope is furnished with Class A weight zinc-coated wires throughout. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Bethlehem Structural Wire Rope consists of six strands made from zinc-coated wire with strands laid helically around a core, such as another strand or smaller wire rope.

The prestretched rope shall meet the required minimum modulus of elasticity. Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The weight of the zinc coating shall be determined by a stripping test made on the individual wires prior to fabrication of strand.

This specification covers zinc-coated steel structural wire rope, prestretched or nonprestretched for use where a asfm, relatively flexible prefabricated zinc-coated multiple-wire tension member is desired as a component part of a structure.
In doing so, we are able to test and certify the following:. Please contact your WW regional sales manager or customer service representative for further information.

Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements. 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. Using SS also offers these advantages:.
This abstract is a brief summary of the referenced standard.
When specified, the wire rope shall be prestretched. These are the features that permit strand to adapt so successfully to structural applications. It can be furnished with Class B weight or Class C weight zinc-coated outer wires or Class B weight or Class C weight zinc-coated wires throughout where additional corrosion protection is required. Reduced Structural Strand Diameter—Now that designers can utilize a smaller diameter strand for the guying system, SS offers a lower cost per foot, allowing the user to cut valuable dollars from the cost of a project.
For any given diameter, wire strand is the least flexible of steel cables. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Structural strand provides a high strength-to-weight ratio, a high modulus of elasticity and a small diameter-per-unit strength. The higher strength results in an increased design factor asfm the guying system. Find a state or province to view Wirerope Works, Inc.

Refer to Table 1 for structural strand data. In addition, WW can obtain material certification from end termination vendors.
Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section.
