PolyPost FAQ

PolyPost Frequently Asked Questions

Why install PolyPost?

1.PolyPosts are NON-CORROSIVE making them ideal in acidic soils or where there’s high salinity which causes steel pickets to rust. Also coastal regions and for water-logged areas such as fencing running through creeks or bounding a lake.
2. PolyPosts are also great for electric fencing as you don’t need insulators for hot wires.

Where can I buy PolyPost?

To keep costs down we ship PolyPosts in crates with 500 posts each and we use the rural retail stores to keep stocks and supply farmers in the quantities they need.

Contact TechPlas if the rural produce store you support does not stock PolyPost and we can provide them with details for getting them in.

Available at:

Leading independent outlets

What does MkII mean?

We launched the original PolyPost in mid-2019 at the height of the drought in many parts of NSW. We found that some farmers and contractors struggled to drive the original product to the required depth in hard ground. So we modified the original version, making the core thicker and stiffer and adding a steel tip. This new version we call PolyPost Mk II.

How do you drive PolyPosts in?

The same way you drive a steel star picket. You can use a hand-held post driver (dolly), a petrol driven or pneumatic post driver. View an installation example here.

What sizes do PolyPosts come in?

Standard PolyPosts are available in the following sizes:
1.50m
1.65m
1.80m

However, we can make PolyPost any length and if you have a requirement for a specific length contact TechPlas about your needs.

How many holes in PolyPost?

All three lengths of PolyPost have 14 holes configured in the same layout as standard steel star pickets.

Is PolyPost available in different colours?

Yes – we have made PolyPost in WHITE, YELLOW, RED and pure BLACK. (NOTE – we refer to the recycled product as “charcoal” and there can be slight colour variation in the standard PolyPost due to it using recycled inputs).
We can also make PolyPost any other colour but minimum order quantities will apply.
Colours other than charcoal are a premium price as only virgin raw material inputs are used.

Are PolyPosts competitively priced?

YES – PolyPosts are competitive with good quality steel star pickets and typically cheaper than galvanised star pickets. Pricing will be affected by your location and quantity bought. When used in electric fencing PolyPosts negate the need to install insulators making them even more cost effective.

Are PolyPosts really made from recycled plastic?

YES – but not just any plastic, it has to be PVC. Most of the recycled material comes from us grinding off-cuts and wastage from our own production or taking our customer’s waste PVC. So we know the quality of the recycled material.

Will PolyPost go into hard or rocky ground?

PolyPost is NOT suitable for excessively hard, compacted or rocky ground. PolyPosts will not break through rocks and excessive pounding when it hits a rock will damage the top of the post. If you are concerned that your ground may be too hard TechPlas recommends getting some sample PolyPosts and driving them into the intended area before ordering a job quantity.

How strong is PolyPost?

PolyPost is not as strong as steel pickets but when used for an electric fence this should not be a major issue as the hot wires will deter animals from pushing the fence. If PolyPosts are pushed over they will bend to around 50-60 degrees and then spring. If PolyPosts are bent beyond 60 degrees there’s a chance it will permanently deform and in rare cases they can even snap.

Can I buy PolyPost direct from the manufacturer?

No – PolyPost is only available through the rural retail channel. We currently deal with CRT/Landmark/Nutrien Ag Solutions, Elders, Norco and many independent rural stores. If you are interested in buying PolyPosts and your preferred rural produce store does not know about them please call TechPlas on (02) 9636 6755 and we will make contact with them.

Are there clips for PolyPost to take electrified tapes?

We are currently working on a clip for PolyPost that can take 12mm and 40mm electric tapes. Unfortunately, the design of the PolyPost profile does not allow standard clips used with steel star pickets to be used.

How far apart should PolyPosts be spaced?

There is no definitive answer to this question. It will depend on whether the fence is electrified or not, what animals are being kept in or out, how many wires are run etc. It is really up to the installer to assess what they feel will work best for their particular application.

Can I pull out PolyPosts with a standard post puller?

Probably not. Many post pullers made for steel pickets have a clamp which wraps around the post. This will crush the PolyPost. However, the Universal Puller with nip roller jaws made by Marchant Engineering works well will with PolyPost. It uses two wheels with cogs to grab the flange of the post and lift it with minimal damage.

Is PolyPosts UV resistant?

Yes – the formulation for PolyPost includes additives to limit UV damage. PVC products perform well in outdoor applications and TechPlas makes other products that are installed outdoors like road guide posts and rainwater downpipes. TechPlas has undertaken accelerated aging tests and believes PolyPost will withstand Australian conditions for around 20 – 30 years.

What temperatures can PolyPost withstand?

Testing done by TechPlas suggests PolyPost will work effectively in temperatures from 0°C to 50°C.

How does PolyPost perform in a bushfire?

Being a plastic based product PolyPost will not respond well to fire. It will not tend to add fuel to a fire but it will soften and eventually melt under sustained extreme heat.
