Compacted Strand Wire Rigging

Compacted Strand stainless steel wire is designed for high performance shrouds, backstays and forestays on sailboats and yachts committed to racing or extended/performance cruising.

The dyformed compact strand structure delivers lower stretch and higher break loads per given diameter than standard 1x19 wire.

The increase in performance comfortably offsets the minimal weight increase.

2.5mm, 3mm and 4mm diameters are available in 1x7 construction ~ 5mm up to and including 12mm diameter is manufactured in 1x19 construction ~ 14mm diameter and larger is manufactured in 1x36

Jimmy Green Marine currently source all their Compacted Strand wire from Petersen Stainless and hamma™ Pro Strand

Jimmy Green Marine operate a strict accountability process for every reel of wire that the Jimmy Green Rigging Team use and record the corresponding batch number on every rigging order.

Traceability is an important feature of the Jimmy Green assurance policy: Stainless Steel Wire - Quality Control and Care

You can therefore be reassured that your rigging will only be made up from top quality fully accredited Petersen Stainless wire.

All wire terminals are roller swaged onto the wire using Wiretechnik Roller Swaging Technology.

Swaging is available in wire diameters from 2.5mm up to 12mm diameter (up to 10mm on site)

All copper ferrule terminations are fitted onto the wire using Cabco Talurit Hydraulic Press Machines.

Wire Termination from 2mm up to 8mm diameter is carried out on site.

WireTechnik and Cabco Talurit are acknowledged throughout the marine industry as the leading manufacturers for top quality, reliable wire termination.

Jimmy Green Marine offer the full range of Sta-Lok, Petersen and Hamma Regatta swage terminals e.g. eye, forks, tees, strap toggles plus all manner of turnbuckle and backstay insulator options. Terminals from Selden, Hasselfors, Bluewave, Navtec and OS/BSI are also available

Petersen Compacted Strand Stainless Steel Rigging Wire

Manufactured in Europe from high quality European AISI 316 stainless steel grade 1.4401

Polished in the fully austentic condition to give maximum corrosion resistance Dimensions and tensile grades conform to EN 12385 and EN 10264 which stipulate tolerances on nominal diameter and minimum tensile strength for wire sizes.

Petersen Compact Strand Facts and Features:

  • 2.5mm, 3mm and 4mm diameters = 1x7 construction
  • 5mm up to and including 12mm diameter = 1x19 construction
  • 14mm diameter and larger = 1x36 construction
  • Compacting process makes it denser, heavier 
  • Sleek, uniform, burnished finish
  • Superior corrosion resistance
  • Appreciably stronger than standard 1x19 construction
  • Increased strength means a greater safe working load factor - the load applied to the rig is a smaller percentage of the break load
  • Lower stretch characteristic than standard 1x19 wire
  • Compact Strand is generally acknowledges as a high performance rigging wire
  • Pre-stressing is not required

Stretch is expressed (in mm) as the increase in length on 1mm for every 100kg tensile load applied

MBL = Manufacturer Break Load

N.B. Table figures are courtesy of Petersen stainless

The Petersen stretch chart illustrates what most sailors know, that wire doesn't stretch very much.

Standard 1x19 wire doesn't stretch enough to be of any concern for standing rigging on cruising yachts.

However the table also demonstrates that Compact Strand is slightly heavier and stretches even less than standard 1x19 wire.
