Chainwire Rolls

Cyclone Security can manufacture a chainwire roll to meet almost everyones needs

 

Wire Types

 

Chainwire fencing rolls are manufactured using a variety of different wire types:
 
  • 2.50mm standard galvanised wire
  • 2.50mm and 3.15mm diameter heavy galvanised or Lifemax (TM) wire
  • 2.50mm and 3.15mm galvanised core P.V.C. coated wire (green or black)
LifeMaxTM wire is manufactured by OneSteel Wire and has a zinc aluminium coating which lasts up to 3 times the life of Zinc Galvanised coating. It has good welding performance and is manufactured in Australia.
 
Please note: Chainwire rolls and assocatiated products made from 2.50mm Standard Galvanized (SG) W02Z wire do not meet the minimum standard for any parts of AS1725-2010
 

Standard Roll Lengths

 
State 1800mm High And Under Above 1800mm High
QLD 20m 10m
NSW 15m 10m
VIC 10m 10m
SA 15m 10m
TAS 10m 10m
WA 15m 10m
NT 20m 10m

 

Selvege Styles

Chainwire is supplied with a barbed or knuckled selvedge as in the diagram below. 

The mesh selvedge is nominated by the purchaser at time of order placement.

In general when a fence roll is under 1800mm high it is provided in a Knuckle/Knuckle Selvedge

Where a top &/or bottom rail is installed, the mesh is laced to the rail/s therefore, normally a knuckle selvedge is required, however barb selvedge can be used. In that situation, the mesh extends above (top rail) or below (bottom rail) and tied or laced to secure

 

 

 

Diamond Size

 

Cyclone Security manufacture chainwire in a number of different diamond sizes ranging from a pitch of 25 to a pitch of 100.  The diamond size varies according to the application.

 

 

Standard Roll Heights

Cyclone Security can manufacture rolls of chainwire in a variety of heights ranging from 600mm to 4200mm. In general, the standard widths are sold in 300mm increments. The actual height of a fence is normally dependent on the application

In a security application a chainwire fence in normally specified at 1800mm, 2100mm or 2400mm high

In a tennis court application a chainwire fence is normally specified at 3600mm high 

Our standard range is as follows:

Fences are specified in the Australian Standards as:
• Class 1 – Medium quality designed for improved durability and life for fencing for long term security purposes such as for government departments and councils.
• Class 2 – Medium/Light designed for industry for medium to long term security purposes such as industrial and commercial installations.
• Class 3 – Medium/Extra Light designed for short term security purposes such as domestic and light duty industrial and commercial.

 

Corner, strainer and end posts shall be 50nn DN/NB and excavated to a minimum depth of 750mm. Intermediated posts shall be 40mm DN/NB and excavated to give a minimum depth of 600mm

Intermediate Posts

Intermediate posts are fence posts positioned at regular, equally spaced intervals between corner, terminal and gate posts to provide support for the chainwire mesh. Where specified by the purchaser, posts may have extensions provided above the top level of the mesh for the attachment of barb wire. 

Intermediate posts are usually equally spaced at 3.3m centres (AS 1725.1-2010) or as specified by the purchaser. It is not unusual for security fencing to have posts specified at 4m centres.

The intermediate barb extensions may be straight or if required, bent at 45° and protruding at 90° to the fence line – see opposite. The barb wire is usually secured on the external side of the posts, however with cranked extensions, the local council may insist that the posts are set back so the extension does not protrude into public space if facing away from the property.

Corner Posts

Corner posts are fence posts at a corner or change of direction and provide support for the chainwire mesh to be strained off. Because corner posts are used to strain chainwire, cable wires and barb wire (when used), they need to be supported sufficiently with a horizontal bracing strut, diagonal bracing stay or top rail. Where specified by the purchaser, posts may have extensions provided above the top level of the mesh for the attachment of barb wire. 

The Corner post barb extensions may be straight or if required, bent at 55° if the extension is facing outwards and set at 45° to a 90° corner – see opposite. If the cranked extension is at 45° to the fence line, then the barb spacings will vary, by being spaced out further. For a typical 150mm barb spacing, the cranked corner post spacing will be 212mm.

The barb wire is usually secured on the external side of the posts, however with cranked extensions, the local council may insist that the posts are set back so the extension does not protrude into public space if facing away from the property.

End Posts

End posts are fence posts used as a terminal post on a fence line and provide support for the chainwire mesh to be strained off. Because End posts are used to strain chainwire, cable wires and barb wire (when used), they need to be supported sufficiently with a horizontal bracing strut, diagonal bracing stay or top rail. Where specified by the purchaser, posts may have extensions provided above the top level of the mesh for the attachment of barb wire. 

Strainer Posts

Strainer posts are fence posts used as an intermediate strainer post on a fence line and provide support for the chainwire mesh to be strained off. They typically are specified over and above a normal specification and are often spaced at intervals of 150m on straight lengths. Because Strainer posts are used to strain chainwire, cable wires and barb wire (when used), they need to be supported sufficiently with a horizontal bracing strut, diagonal bracing stay or top rail. They are braced in both directions in line with the fence – see below right. An alternative is the bracing panel, consists of 2 strainer posts, rail & cable wire and turnbuckles – see below left. 

Gate Posts

Gate posts usually are used in pairs to frame a gateway. Gate posts at the end of a fence run provide support for the chainwire mesh to be strained off. Because Gate posts are used to strain chainwire, cable wires and barb wire (when used), they need to be supported sufficiently with a horizontal bracing strut, diagonal bracing stay or top rail. Where specified by the purchaser, posts may have extensions provided above the top level of the mesh for the attachment of barb wire. 

The gate post barb extensions may be straight or if required, cranked (50mm bent, 80mm cut & welded) at 45° and protruding at 90° to the fence line. If the gate post has cranked barb extensions, the gate frame barb supports always remain straight otherwise the cranked extension would hit the post’s cranked extension when opening the gate – see opposite. 

The barb wire is usually secured on the external side of the posts, however with cranked extensions; the local council may insist that the posts are set back so the extension does not protrude into public space if facing away from the property.

Bracing Stays & Rails

Bracing stays and bracing rails are fitted to all corner, end, intermediate strainer and gate posts unless specified otherwise or there is a top rail fitted. Because these terminal posts are used to strain chainwire, cable wires and barb wire (when used), they need to be supported sufficiently with a diagonal bracing stay or horizontal bracing rail.

Back Stays

Back stays are fitted when specified to intermediate posts at 90° to the fence line. They are generally spaced at a specified number of intermediate posts e.g. every 5th intermediate post. There is also the option to use them on gate posts where the gates are large and the posts require additional support to carry the weight or when otherwise specified. When used on gate posts, they are fitted at 60° to the fence line angling away from the gate opening back along the fence line. This allows the gate to open more than 90°.

 

Fencing Wire

 

Lacing Wire/Tie Wire

  • Lacing & tie wire are commonly used in the following applications. For every 100m of fence, allow 3kgs (Galv) & 4kgs (PVC) plus above.
  • Lacing chainwire to top & bottom pipe rails
  • Lacing chainwire vertically to terminal posts
  • Tying chainwire mesh to intermediate posts
  • Tying helicoil cable to intermediate post
  • Tying barb wire to posts - barb extension
  • Tying chainwire mesh to horizontal cable wires as a substitute to netting clips (‘ring fasteners’)

Netting Clips

Netting clips are an alternative to using tie wire to fix the chainwire mesh to the supporting cable wires. 

The clips are secured at 320mm maximum spacing or every 4 diamond using a hand operated tool similar to a pair of pliers. The clips are closed tightly around the cable wire and the wire of the mesh. 

Cable Wire

  • Twin double twisted support cables (3.15mm diameter) are used as a double strand plain horizontal cable, which is twisted together at intervals between intermediate posts to form a tensioned spiral effect, allowing the chainwire mesh to be adequately supported between all posts. To gain this effect, each strand is looped around alternative intermediate posts but never both around the same post.  

Helicoil

  • Helicoil cable (4.00mm diameter) is a single strand horizontal cable which is strained taut between and secured to all terminal posts. The helicoil cable is secured to the mesh side of all intermediate posts with double cross ties of 2.00mm lacing wire. As with double twisted cable option, the purpose is to support the chainwire mesh between all posts.

Barbwire

  • Barbwire is used in applications where additional security is required. The most common used barbwire is 1.57 high tensile with a reverse twisted pattern construction for maximum strength and barbs at 100mm spacings. Typically, the barbwire is strained taut between terminal posts above the chainwire at predetermined spaces

 

Chainwire Gates

 

Gates can be fitted to gate posts or other solid structure e.g. brick wall so as to allow the gate to swing freely without hindrance. Unless specified otherwise, gates are supplied fitted with equipment to enable locking, keeping open etc – see below options. The gates are to have sufficient clearance to maintain security when closed and set at a height that allows the gate to swing without scraping kerbs and other obstacles.

 

Fence Fittings

 

All rails & stays are connected to posts using galvanised bolted split clamp-on type fittings as shown on this page. Unless otherwise specified, all fitting sizes relate to nominal bore pipe dimensions (NB).

Gate Fittings - Hinges

Gates are connected to posts or other suitable solid structure using galvanised bolted split clamp-on or gudgeon type hinge fittings as shown on this page. Unless otherwise specified, all fitting sizes relate to nominal bore pipe dimensions (NB).

Gate Fittings - Locks

Gates are retained in the closed position by either chain or shootbolt depending on type and retained in the open position by dropbolts as shown on this page. Unless otherwise specified, all fitting sizes relate to nominal bore pipe dimensions (NB).

 

Australian Standards

 

The Australian Standard for chainlink security fencing is covered by AS1725-2010 - Parts 1-5

 

The Australian Standard for Chain-link Fabric Fencing and Gates (aka Chainwire) replaces AS1725-2003 – “Chain-link
fabric security fences and gates"
 
AS1725-2010 expands on the main application areas of chain-link fabric fencing and gates, but ensures that
the five (5) different sections, four (4) which are new, are consistent in both types and applications of materials
and installation standards.

The revised standard and comprises of 5 parts: 

AS1725.1 – 2010 Chain link fabric fencing – Security fencing & gates – General requirements
AS1725.2 – 2010 Chain link fabric fencing – Tennis court fencing – Commercial
AS1725.3 – 2010 Chain link fabric fencing – Tennis court fencing – Private/Residential
AS1725.4 – 2010 Chain link fabric fencing – Cricket net fencing enclosures
AS1725.5 – 2010 Chain link fabric fencing – Sports ground fencing – General requirements
 
Chain-link fabric and associated wire made from Standard Galvanized (SG) W02Z wire does not meet the minimum standard for any parts of AS1725-2010
