STAYTIGHT
STOCKYARD CABLE
Typical installation of Staytight cable using ironbark posts and steel capping rail. Sandalwood Feedlots, Dalby, Qld.
WHAT IT IS :- It is a high tensile, high quality but low cost wire strand comprised of 7 wires or 19 wires, depending on the size. It is
galvanised and oiled.
Commonly used sizes are 6.5mm and 8.5mm for holding yards, and 10mm for heavy duty areas such as feedlots.
WHAT IT DOES:- When used as stockyard wire it provides a heavy duty barricade that does not need retensioning. This is a major
benefit in intensively used areas such as feedlots. This characteristic also simplifies construction and so reduces cost. Extra fittings
such as turnbuckles are not needed.
HOW IT DOES IT:- Because Staytight cable is elastic, it stretches and rebounds, instead of moving the strainer post when impacted
by animals, vehicles, or frosty nights. This beneficial property, only available in Andromeda Staytight wire, is provided by the helical
shape of the wires.

Extensive use of Staytight wire to infill panels in a large feedlot in the Riverina of NSW. Yambinya Feedlot, Deniliquin.
Constructed by Gallagher Fencing - Deniliquin.
Originally made from used mining ropes, this material has
created a quiet revolution in the construction and upkeep
of yards, because of its high quality steel, elastic properties and economical termination methods.
So far we have manufactured about 3000 tonnes of this
material.
It should be noted that nearly all of this, some of it installed
15 years ago, is still in use today, making it a very durable
industrial material indeed.
Picture at right shows another Riverina feedlot under construction. Note this fence has no capping rail to counter the
compression loads generated by the tight wires.
With this simplified and economical design it is important to
ensure strong and durable strainer assemblies, usually 2 or
3 steel posts, braced together and set into concrete at least
1500 mm deep. This design can only be used on straight
runs, but the distance between strainers is not limited.
Typical termination method
for Staytight wire
This picture shows the simplicity with
which Staytight wire is terminated into
the posts. It is simply passed round the
post and wrapped back into itself and
made off with two or threerope clamps.
It should be noted that no turnbuckles
are needed with this material, because
it is installed under tension, it will remain this way for a long time unless the
strainers move.
This is a typical construction for a heavy
duty yard. We recommend at least 4
wire runs (preferably 5), no more than
250mm apart, preferably 300mm.

ANDROMEDA STAYTIGHT CABLE - General notes, sizes and specifications
Technically, Staytight cable is a wire strand – that is a number of wires are twisted together to
form a more flexible entity than a single wire filament of the same cross-sectional area.
This construction is known as seven
wire strand.
The 6.5 and 8.5mm Staytight are of
this construction
This construction is known as a nineteen
wire strand. The 10mm and larger are of
this construction
The reason for using stranded wire, is to provide a material that is thick enough to be visible and strong enough, yet is
flexible enough to bend and connect into the fence structure.

Note: Staytight wire can be made any size if the application can justify a special design and suitable production run.
A minimum production run for special sizes is approx. 15,000 metres.
Stranded wire is also used for structural work at feedlots
The stranded feedstock wire from which Staytight is made is also used in the construction of shade structures over
the feedlots. Enquiries for this application are welcome. The 8.5mm is available in reels of 4,700 metres, and the
10mm is available in reels of 4,000m. Note: the reels are very heavy! Need good lifting gear.
Andromeda Industries also manufactures or processes a number of other materials, mostly from used
conveyor belts, which are often used in yards and general agricultural applications.
• Splitbelt, made from conveyor belts, and used for yards, fences, horse floats, stables
• Holeybelt, which is Splitbelt with 20mm holes used for mats for utes, trucks and horse floats
• Rubber rails, precision cut strips of conveyor belt, used for arena fencing, safe for horse and rider
• Envirobelt, heavy duty Holeybelt used for landscaping, beach access and dune conservation
• Blasting mats, woven from conveyor belts, used to prevent rock fly when blasting in city areas

Some other uses for Staytight wire
Staytight wire has been used extensively in fencing
wheeled trespassers out of National Parks. The high
strength wires are very hard, and no normal type of wire
cutter will breach it.
Staytight wire pulled up tight over simple frames supports
1800 mm wide Splitbelt to form a long feed trough in
so-called “sacrifice paddocks” in NW of NSW.
Some notes on fence design and construction using Staytight wire
Various combinations of steel tube and wire are possible. Secure strainer assemblies are critical.
Well designed bracing method ensures that the Staytight
wire has a good anchorage. This is needed at both ends
of a straight run.
