Chain Wire Fences and Gates are a popular choice for commercial and residential fencing projects as chain wire is a strong, flexible and durable product that provides security at a reasonable price.

In commercial and industrial areas it is often used for Security fencing when topped with barb or razor wire

A chain-link fence allows for great visibility and is commonly used in garden areas, playgrounds, high screen golf courses, sports fields, railways and airports.

Chain wire’s flexibility makes it a great choice for cricket nets, tennis courts, and its springy texture can protect horses from injury in horse enclosures.

Internal chain wire partitions can be used to protect factory workers from machinery and to separate storage areas and storage cages.

Chain Wire Fencing Bunnings – Gladesville NSW – March 2021

Bunnings Gladesville NSW needed an additional secure storage area for their various materials like sand, cement and concrete bags. To secure the area on level P2 we needed to install 40 lineal metres of 3-metre high chain wire fencing.

The design included 3 rails black on black chain wire fencing. Plus 3 single-chain wire gates 2400 wide x 2900mm high. All posts were flanged and fixed to the concrete floor and ceiling. Completed March 2021

Railless Chain Wire Fence

As the name suggests a railless chain wire fence does not have a supporting top, bottom or mid-rail that runs between your posts. A railless chainwire fence is often used on residential and rural projects like Koala fencing.

Top Rail Chain Wire Fence

A top rail provides extra support, strength and durability to your chainwire fence. The fence has a more complete appearance with the extra top rail. Chainwire tennis courts fences usually include a top rail as part of their design.

Top, Bottom and Mid Rail Chain Wire Fence

Depending on your security needs and budget you can add a bottom rail or mid-rail to further strengthen your fence and perhaps enhance the appearance of your fence.
