Fence Drawings to AS1725-2010

The attached drawings and specification is to provide you with a simplified summary of
AS1725 AFIA STANDARD DRAWINGS FOR RAIL-LESS, CHAIN-LINK SECURITY FENCING

Previously chain-link fencing has been specified as chainwire fencing, chainmesh fencing, wire mesh fencing or by a generic brand name called Cyclone fencing.

The Australasian Fence Industry Association is committed to maintaining high standards for the supply and installation of chain-link (chain mesh) security fencing.

Following frequent requests from architects, engineers, specifiers, local government authorities and fencing contactors for information on chainmesh and chainwire security fencing details, the AFIA has produced two standard chain-link security fencing drawings.

The fencing details on these drawings are compliant with the Australian standard AS1725.1- 2010, Chain-link fabric Fencing – Security fences and gates.

First drawing features a heavy duty chain-link security fence with 3.15mm wire for longer, durable service life in higher security applications.

Second drawing, light duty chain-link security fence, has 2.50mm wire and may be selected for light industrial applications where security and durability are a lower priority.

The Australian Standard for Chain-link Fabric Fencing and Gates (aka Chain Wire Mesh) AS1725-2003 – “Chain-link fabric security fences and gates” was updated in September 2010, with the new standard known as AS1725-2010 – Parts 1 to 5.

The new version 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.

AS1725-2010 – Chain-link Fabric Fencing

Part 1 – Security Fences and Gates

  • Replaces AS1725-2003
  • Part 1 – Essentially has only minor changes to AS1725-2003, e.g.
  • In addition to AS/NZS 1163, Galvanized Pipe that meets either AS1074 & EN10255 is also now accepted.
  • Chain-link Fabric (CLF) and associated wire made from Fuse Bonded Polymer (FBP) wire, with a base metallic coating not less than W02Z has been added to AS1725-2010.

Summary of major specifications which remain unchanged from AS1725-2003 to AS1725-2010 - Part 1

 

  • DN50 Medium Grade (3.6mm wall thickness) galvanized pipe posts are the minimum size & type posts that can be used for all Terminal posts, i.e.; End, Corner & Gate posts.
  • DN40 Medium, Light or Extra-Light galvanized pipe posts are the three (3) DN40 pipe grades that are listed in AS1725-2010 which can be specified as the minimum size for Intermediate posts.
  • Chain-link fabric and associated wire made from; Heavy Galvanized (HG) W10Z wire, Zinc/Aluminium-Alloy (ZA) W05Z5A wire& PVC (Polyvinyl Chloride) wire with a base metallic coating not less than W02Z,remains unchanged and are all accepted.
  • 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
  • The core wire diameter for the manufacture of chain-link fabric is either; 2.50mm dia. Light Duty or 3.15mm dia. Heavy Duty.
  • The maximum pitch (diamond) size for chain-link fabric is 50mm nominal pitch, measured diagonally across the diamond.
  • Post spacing’s remain unchanged at a maximum of 3330mm post centres.
  • Wire used for lacing wire MUST be 2.00mm core wire for all parts of AS1725-2010, i.e. 1.57mm core Tie wire can be only used to secure chain link fabric to horizontal cable wires.

Part 2 – Tennis Court Fencing – Commercial

 

  • Includes guidelines for purchasers to assist with the selection and nomination of components to establish the final fence specifications and design requirements for Commercial Tennis Court Fencing.
  • Chain-link fabric: 45mm pitch x 3.15mm Heavy Duty is the minimum duty CLF that is specified, i.e. CLF made from Light Duty 2.50mm core wire is not recommended in Commercial Tennis Court Fencing applications.
  • Commercial Tennis Courts provide for a heavier design specification.
  • Intermediate posts have been increased to a minimum DN50 (60.3mm OD) Medium or Light Grade pipe posts.
  • Corner posts shall be a minimum DN80 (88.9mm OD) galvanized Medium Grade pipe.
  • Extra Light galvanized pipe does not comply with this section of Tennis Court Fencing.
  • Post spacing’s at a maximum of 3330mm post centres.
  • The intermediate fence members within this Standard make no allowance for signage, wind break materials or creepers attached to tennis court fencing.
  • An engineer’s recommendation and design for fence members and/or attachment of backstays should be sought depending on wind break materials proposed and wind category area the fence is exposed to.

Part 3: Tennis Court Fencing – Private/Residential

 

  • Includes, guidelines for purchasers to assist with the selection and nomination of their choice of components, to establish the final fence specifications and design requirements for tennis court Private/Residential fencing, to suit their site application.
  • Chain-link fabric: both 45mm pitch x 3.15mm Heavy Duty CLF or 45mm pitch x 2.50mm Light Duty CLF can be specified.
  • This section provides for a lighter design specification for Private/Residential Tennis Courts, compared to Commercial Tennis Courts.
  • The minimum size for Corner posts has been increased from DN50 (60.3mm OD) galvanized Medium Grade pipe to DN65 (76.1mm OD) galvanized Medium Grade pipe.
