NEW CHAINLINK STANDARD FOR SPORTING FENCING GETTING CLOSER

The CE008 Australian Standard’s committee will meet in Sydney on 28th January 2010 to consider the comments received by Standards from interested parties regarding the proposed draft Australian Standard for Chain Link security and sporting fencing.

This new standard will incorporate both the existing AS1725-2003 Chain link fabric security fences and gates and new sections on tennis court fencing, cricket net enclosures and perimeter sports ground fencing.

The Association is represented on this committee by a number of members including Chairman Ray Otter, (VIC) Craig Gibbens, (NSW) Merv Just (NSW) and Peter Kurmis (SA)

IGNORANCE IS NO EXCUSE SO THEY SAY

Recently the Association was contacted by a contractor inquiring whether AS1725 -2003 Chain - Link fabric security fences and gates was still in draft standard form.
The contractor had just completed a run of several kilometres of chain link security fencing where the specification called for the fencing to comply with the current Australian Standard.
His sub contactor had spaced the intermediate posts at 4.00 metre centres. Evidently this spacing had been the norm locally prior to introduction of the 2003 standard. The client had been made aware the current Australian standard required intermediate posts to be spaced at 3.330 centres and insisted the posts be reposted at the correct spacing and was not prepared to compromise.
AS1725-2003 is the current chain link security fencing standard. It will be replaced once the current review is completed, likely to be in early 2010. Are you sure your subcontractors are aware of the installation requirements in the
Australian standard?

 

CHAIN LINK Security fencing AND GATES standards

Chain Link Fabric Fencing products are produced to Australian Standard AS 1725 – 2003 Chain Link Fabric Security Fences & Gates which replaces AS 1725 – 1975.
The new Standard incorporates a number of changes which are summarised below.

SUMMARY of NEW SECURITY FENCING STANDARDS

AS 1725 – 2003 sets out specific requirements for Chain Link Fabric security fencing and gates available in a range of alternative designs and combinations, with options for fence height, fabric, wire coatings, wire service duty, pipe grades & tables and types of security fencing design options.

Purchasers will need to refer to advisory appendices to make a selection of components within the scope of this standard to specify the security fencing required for their application.

Fabric Height
Optional heights are 1800mm, 2100mm & 2400mm

Wire Coatings
Metallic coatings either heavily galvanised (HG) – W10Z min. or zinc/aluminium alloy – W05Z5A min.
Plastic coatings either poly vinyl chloride (PVC) or polyethylene (PE) over a zinc coating of W02Z min.

Service Duty

Light duty: is manufactured from 2.50mm dia. core wire and is used in lighter applications.

Heavy duty: is manufactured from 3.15mm dia. core wire and is used in more durable applications .eg. security, industrial and sports fencing.

*Light duty 2.50mm chain-link fabric provides only approx. 60% of the load bearing capacity of heavy 3.15mm chain-link fabric.

Class 1 – Medium Grade
Class2 – Medium/Light Grade
Class3 – Medium/Extra Light Grade

Fence Designs
Type 1 – Rail-less Security Fencing either plain top or 3 barb top
